CDC Publishes Draft Norovirus Prevention Guideline

The Centers for Disease Control and Prevention (CDC) is inviting public comments on the draft Guideline for the Prevention and Control of Norovirus: Gastroenteritis Outbreaks in Healthcare Settings.” The Association for Professionals in Infection Control and Epidemiology (APIC) says it will be submitting its official response to the document, and APIC members are encouraged to respond individually. Comments are due to CDC by July 16, 2010.

To evaluate the evidence on preventing and controlling norovirus gastroenteritis outbreaks in healthcare settings, the guidelines’ authors examined published data addressing three key questions: What host, viral, or environmental characteristics increase or decrease the risk of norovirus infection in healthcare settings? What are the best methods to identify an outbreak of norovirus gastroenteritis in a healthcare setting? What interventions best prevent or contain outbreaks of norovirus gastroenteritis in the healthcare setting?

Recommendations in the draft guideline touch upon cohorting of patients with isolation precautions observed; hand hygiene; patient transfer and ward closure; diagnostics, personal protective equipment; environmental cleaning; staff policies and more.

Norovirus Called "The Most Common Cause" Of Food-Borne Illness Outbreaks By CDC

Norovirus is on the upswing in the United States, a new report by the Centers for Disease Control & Prevention (CDC) suggests.

No national surveillance system exists for Norovirus except where food-borne transmission is suspected. In last half of 2006, state public health departments began reporting more outbreaks involving acute gastroenteritis (AGE). Many of these involved residents of long-term care facilities.

Two years ago, in the (Aug. 24, 2007) Morbidity & Mortality Weekly Report (MMWR), CDC confirmed that “ a national increase has occurred in the frequency of AGE outbreaks caused by norovirus (including fatal cases in long-term--care facilities). Two new co-circulating GII.4 norovirus strains emerged nationwide in 2006 and likely accounted for this increase in activity.”

In today’s MMWR, CDC takes a more robust look at food-borne outbreaks in 2006 and finds Norovirus is “the most common cause.”  In an analysis titled: “Surveillance for Foodborne Disease Outbreaks --- United States, 2006,” CDC breaks down the outbreaks for 2006 on which it has data.

“A total of 1,270 Food-Borne Disease Outbreaks (FBDOs) were reported, resulting in 27,634 (illness) cases and 11 deaths.

“Among the 624 FBDOs with a confirmed etiology, norovirus was the most common cause, accounting for 54 percent of outbreaks and 11,879 cases…” CDC reports.

In 621 outbreaks involving 18,111 cases, there was a single confirmed etiologic agent responsible. In 55 percent of those outbreaks (343) involving 66 percent of the cases (11,981), the cause was a virus. (Bacteria, parasites, and chemical agents caused the remainder.)

Calicivirus caused 337 (98 percent) of the confirmed FBDOs attributed to viruses; and all calicivirus outbreaks reported in 2006 were attributed to norovirus.

Holland, MI Parties Like Norovirus Is All In Its Past; And There Is No Swine Flu In Its Future

This past weekend in Holland, MI, "town and gown" activities included Hope College's graduation and class reunions; and the annual Tulip Festival.   Out of concern for Swine Flu, there was no kissing at graduation.   Handshakes, however, were encouraged.

And while there were already a couple of confirmed cases of Swine Flu in Michigan, and certain to be more as this week goes forward, Hope College enjoyed a worry-free celebration weekend.  So much different  than last November when a norovirus outbreak closed down the Holland campus and made more than 500 people sick.  We first reported on the Hope College outbreak here.

The Grand Rapids Press reported that: "Visitors were either unaware or not worried about 10 probable cases of swine flu among Hope students, announced late Friday afternoon by the Ottawa County Health Department."

"Everybody is more aware after that (norovirus) experience, says Jonathan Hagood, 34, who teaches Latin American history at Hope. Since that outbreak, hand-washing and hand-sanitation stations were added around the campus.

"We are seeing a more proactive response because as a campus we had a trial run," he said.

Fewer People Suffering This Winter in the UK

Across the pond, also known as the North Atlantic Ocean, comes word that Norovirus might not be as bad in England and Wales this winter as last. The UK Press Association reports:

Cases of flu appear to be falling across England and Wales but experts have failed to rule out a future rise.

The latest data from the Royal College of GPs suggested cases have fallen from 68.5 per 100,000 people to 41.3 in just one week.

Cases of the common cold have also dropped from 355.3 per 100,000 people to 184.7.

A spokeswoman for the College said it was unlikely that flu would hit a nine-year high as previously predicted.

There is concern that people returning to work from the long holiday break could put others at risk.

Professor Steve Field, chairman of the College, warned that people returning to work and school could easily spread flu and the vomiting bug norovirus.

"GPs are coping and this is by no means a crisis," he said.

"But I think a lot of people are looking to us because they want a sick note.

"My prediction is that people are coming back to work or school and they are circulating influenza and transferring it to each other. We think cases of flu and norovirus will go up again."

Brits Get Ready For Another Round of Norovirus

Brits call it "the vomiting bug" and they are getting ready for its return, reports the UK's Daily Star.   Last winter’s epidemic saw an estimated 200,000 people a week struck down by the norovirus.   Now, between  doing its  best to keep the soft porn  business  alive,  the  Daily Star is doing its best to  prepare  folks  for  still more norovirus.   It  reports:

The winter vomiting bug that caused chaos earlier this year is set for a terrifying comeback.  Health experts fear the norovirus will once again hit hundreds of thousands of Brits.

Already, hospital wards in Worcestershire have been closed amid signs that the sickness and diarrhoea bug has claimed a wave of new victims.


NHS Direct has been advising people to treat the bug with an anti-diarrhoea treatment such as Imodium as well as drinking plenty of fluids. Experts warn the elderly are particularly at risk and recommend staying at home to avoid spreading the bug.

Rhode Island, New York, & Minnesota All Reporting Norovirus

Food prepared at the East Greenwich Gourmet between July 30th and Aug. 1st should be tossed because it might be contaminated with Norovirus.

Rhode Island public health officials discovered the problem when every other guest at a weekend event serving East Greenwich Gourmet foods got sick.

In other Norovirus news, the New York Department of Health issued an advisory to camp directors and medical staff about the spread of the bug through the state's many summer camps.

And in Minnesota, 20 people who attended a Rochester an Aug. 1 wedding reception became ill after "eating tortilla chips contaminated with norovirus, possibly from fecal matter."

Oh Boy!

Common Misspellings of Norovirus - Noravirus, Norvirus, Noroviruses, Nurovirus

Noroviruses are estimated to cause 23 million cases of acute gastroenteritis (commonly called the "stomach flu") in the U.S. each year, and are the leading cause of gastroenteritis. Of viruses, only the common cold is reported more often than viral gastroenteritis (norovirus).

Noroviruses may cause more outbreaks of foodborne illness than all bacteria and parasites. They can cause extended outbreaks because of their high infectivity, persistence in the environment, resistance to common disinfectants, and difficulty in controlling their transmission through routine sanitary measures.

The norovirus is transmitted primarily through the fecal-oral route and fewer than 100 norovirus particles are said to be needed to cause infection. Transmission occurs either person-to-person or through contamination of food or water. Transmission can occur by touching surfaces or objects contaminated with norovirus and then placing that hand in your mouth; having direct contact with another person who is infected and showing symptoms; sharing foods or eating utensils with someone who is ill; exposure to aerosolized vomit; and consuming food contaminated by an infected food handler.

Norovirus Hits Florida Coast Resort

Do you think it's possible that some British tourist decided the best way to get away from the norovirus outbreak would be to check into a nice Florida beach hotel? 

If that traveler exists, then just think about all those other unlucky guests at the Hilton Singer Island Resort in Riviera Beach, Florida where 83 people have been struck by the norovirus.  Here's what the Associated Press reports:

Health officials have identified a highly contagious virus as the cause of an outbreak that sickened at least 83 people at a beachfront resort hotel.

Guests and employees at the Hilton Singer Island Resort first reported the flu-like symptoms on Jan. 10.

Health officials were called in after three people were hospitalized.

Test results confirm that the outbreak was norovirus, a highly contagious virus that causes diarrhea, vomiting, nausea, cramps and other symptoms, officials said.

"It spreads easily and quickly," said Tim O'Connor, spokesman for the Palm Beach County Health Department. "We've asked them to completely disinfect everything."

AP's complete report is found here.     Also, Bill Marler gives some legal insights  here.

Bill says showing how the virus is transmitted is hard.  He asks:  "Was it foodborne?  Was it an ill worker?  Ill patron?"

 

One cruise passenger's experience

We recently were contacted by a woman who posted about her cruising experience on her blog, The Savvy Old Lady's Cruising & Travel Tips.  Here is an excerpt of her blog post about a recent cruise trip she took. 
For the next three days countless PA announcements, many by the Captain himself, were made, especially at meal times, about the necessity of washing your hands before each meal. Necessary, yes, but somehow a little disconcerting when you were eating your lunch and listening to someone talking on the PA about the symptoms of Norovirus and Norwalk like virus, namely diarrhea and vomiting. There were many areas that were closed for at least three to four days or the entire cruise. They included part of the Windjammer, the twenty-four hour pizza, sandwich and desert bar. Some areas, such as Johnny Rockets, a wonderful hamburger and milk shake restaurant and the arcade (there was a special concern about children and teens and hand washing) were close for the entire voyage. Passengers were not permitted to remove food from the Windjammer or dining rooms so we could not eat on the open decks or bring food to our rooms (room service did operate normally though after the second day). We were told the reason for this was so the crew would know where all the food was going. Well big surprise all the revenue center food and beverage outlets (coffee shop, Ben and Jerry’s ice cream shop and the bars) on board permitted you to take food out. Hmmm, doesn’t take a brain surgeon to figure out that Royal Caribbean Cruise Lines was losing money on this cruise and I suppose that they had to make the revenue up for it somewhere.

Symposium looks at preventing Norovirus

Every health department should follow in the foot steps of Kalamazoo County.  Noroviruses are estimated to cause 23 million cases of gastroenteritis in the U.S. per year. Full Story

KALAMAZOO -- Health officials say it spreads easily from person to person, but it can be prevented.

Thursday, Kalamazoo County Health and Community Service Department officials will hold a symposium to teach long-term and institutional care providers how Norovirus is spread and how to prevent it.

Last year, there were 145 Norovirus outbreaks in the State of Michigan.

Young Girl May Have Died From Norovirus

Full Story from Craig Huckerby at Soonews.ca

Onatario, Canada - A source to SooNews.ca reported that a three year old girl from Dubreuilville died from the Norovirus at the Lady Dunn Hospital in Wawa last weekend.

According to one source "many many kids in Dubreuilville have been sick" The children are being transported to the Wawa Hospital for treatment.

Dr. Allan Northan from the Algoma Public Health, would not confirm or deny the death in Wawa. No one from Lady Dunn Hospital in Wawa will confirm this news or wished to comment on this case.

Norovirus toll climbs to nearly 400 at rehab center

Stephen Smith of the Boston Globe Staff wrote:

Boston health officials reported today that their review of an ongoing outbreak of gastrointestinal illness at Hebrew Rehabilitation Center shows that 241 patients and 151 staff members have fallen ill since Feb. 21.

Those figures are substantially higher than Friday, when the Boston Public Health Commission last released figures on the outbreak at the Roslindale facility. Then, 225 patients and 119 staff were listed as having experienced nausea, vomiting, and diarrhea -- classic symptoms of norovirus, the infection that has sickened tens of thousands in New England and across the country this winter.

But Tom Lyons, spokesman for the Boston health agency, cautioned that the latest numbers, which indicate a total of 392 people have become ill, do not necessarily reflect a burst of new infections. Instead, the city's investigation is identifying people who became sick earlier in the outbreak but who weren't included in the count.

In the past day, only three new cases have been recorded, Lyons said. Still, he said, city disease trackers are reluctant to declare that the outbreak is trailing off until there have been several additional days when few if any additional infections are reported.

Norovirus sickens at least 100 at Billings competition

A stomach illness suspected to be the highly contagious norovirus has sickened at least 100 people who took part in a regional dance competition last weekend, health officials said Wednesday.  Norovirus, also called the Norwalk virus, causes nausea, vomiting, diarrhea and stomach cramping, and can lead to more serious illnesses in the elderly and infirm. Billings suffered a community-wide outbreak last year, and several nursing homes were struck with the disease earlier this winter.  "It's still early in our investigation. We don't know exactly what we're dealing with yet," said Barbara Schneeman, spokeswoman for the Yellowstone City-County Health Department.  Schneeman said most of those reporting symptoms took part in or attended the Spotlight Dance Cup Regional Dance, held March 9-11 at the Billings Holiday Inn.

Norovirus sharing spotlight with flu this season

According to WAFF News - Outbreaks of norovirus are popping up everywhere

The height of flu season is upon us, but this year, there's another illness that's grabbing the spotlight. Outbreaks of norovirus, the nasty group of stomach bugs that get attention when they hit a cruise ship, are showing up everywhere. It closed a Washington hotel and is popping up on college campuses and in communities across the US.

"It's epidemic proportions in many places in the country unfortunately," says Eliana Perrin, MD, University of North Carolina Pediatrician.

It is norovirus. A group of bugs most people know as the stomach flu. Perrin has seen a number of cases. "I've actually seen it more as a parent. I've seen some children in our daycare. They're affected, their families are affected, everybody is sick."

Across campus, Scientist Ralph Baric runs a norovirus lab. He says this year's rampant outbreaks are linked to a strain called G24 that first emerged about a decade ago. "It's been changing every year this year seems to be particularly hot," says Baric.

It's causing a menu of stomach woes that often appear within 18 hours of exposure to the highly contagious virus. "Symptoms end about 48 hours later." People can still spread norovirus for weeks after the symptoms are gone and so can some people who never have symptoms. "About 30 percent of people we've done hematology studies with can be infected but don't actually become severely affected with clinical disease," says Baric. "Do the best you can with hand washing particularly after diapering a child," says Perrin.

More reason to keep washing those hands.

Norovirus Hits N.J. College Campus


At Least 124 Sickened

FLORHAM PARK, N.J. -- At least 124 students have been sickened in a suspected norovirus outbreak at a New Jersey college.

A spokesman at Fairleigh Dickinson University's Florham Park campus said students began falling ill Thursday. He said an undetermined number of faculty and staff members also have been sickened.

Crews are cleaning dormitory bathrooms and dining halls. The recreation center and pool were shut down for 24 hours for cleaning. Hand sanitizer is being distributed at the library, computer labs and the dining hall. Also, students are being urged to wash their sheets in hot water.

The 24-hour virus is spread person-to-person and causes flu-like systems including nausea, vomiting and diarrhea.

Florham Park health officials say test results later this week should confirm the cause of the outbreak. There are about 3,700 students on campus.

Avoid raw oysters from Texas



THE ASSOCIATED PRESS - HOUSTON

The Food and Drug Administration says consumers should avoid eating raw oysters harvested from San Antonio Bay in Texas because more than two dozen people in Maryland became ill last month.

The FDA said 25 people developed nausea, vomiting, diarrhea and other symptoms after eating raw Texas oysters at a food event in Maryland during Feb. 9-11.

Testing by the Maryland Department of Health and Mental Hygiene indicated they had contracted norovirus, the FDA said. The virus can cause flu-like symptoms that may linger for several days.

The oyster beds in San Antonio Bay were shut down by the Texas Department of Health Services on Feb. 24 and remain closed while the FDA investigates.

Norovirus hits jail in Richmond

Another major norovirus outbreak forced Richmond's overcrowded jail to quarantine hundreds of inmates. And the nasty stomach bug may also have hit doz- ens of students and staff members at three Henrico County schools.

The jail quarantine, imposed yesterday afternoon, affects 271 men in the jail's G Building, said Richmond Sheriff's Office spokeswoman Tara Dunlop. It will last until at least Friday, when the jail's doctor will decide whether the outbreak has passed.

Henrico school officials said students and staff at Shady Grove Elementary School and Highland Springs and Deep Run high schools started showing signs of the illness this month. In Hanover County, officials report four confirmed cases of norovirus.

Norovirus causes vomiting, diarrhea and stomach cramps.

Norovirus Infects Nursing Home Residents, Patients

WESTMORELAND COUNTY, Pa. -- No visitors are allowed in and no patients are allowed out of a Westmoreland nursing home Tuesday that has residents and workers who have been infected with a highly contagious virus.

The Health Department said a strain of norovirus has made its way to Bethlen Nursing Home in Ligonier and has sickened half of the residents and staff, bringing the total number close to 85.

The nursing home said it's doing all it can to stop it from spreading.

Norovirus vaccine near, researchers say

Hundreds of Boston residents and some Boston University students who ended up in the emergency room with the norovirus this winter may take comfort in a recent research breakthrough that may help prevent them from getting infected next year.

The first isolated lab culture of the norovirus human strain, often responsible for causing stomach flu, was produced by researchers from Arizona University, Pacific Northwest National Laboratory, Tulane University and the University of Arizona. The project, published this month in the Centers for Disease Control's Emerging Infectious Diseases journal, came after 30 years of failed attempts to isolate the virus.

Timothy Straub, lead researcher at Pacific Northwest National Laboratory, said the research could eventually lead to a vaccine similar to a typical flu shot.

"[The new methods] may provide this critical link in developing new treatments and vaccines," he said.

Michigan hit harder by flu-like virus

As an emergency room doctor at Beaumont Hospital, Royal Oak, Frank McGeorge has treated countless cases of norovirus, the stomach virus notorious for canceling cruise ship vacations.

But McGeorge has also suffered the highly contagious illness, which can make patients agonizingly nauseous, he said.

"Norovirus is incredibly distressing to people," McGeorge said. "And from a medical standpoint, there's nothing we can do to treat it, except fluids, anti-nausea medicine and time."

McGeorge and other physicians in Metro Detroit and across the state are dealing with more reports of norovirus outbreaks at nursing homes, restaurants, schools and other public places, health officials say.

Last year, 144 norovirus outbreaks were reported in Michigan -- a 323 percent jump from the 34 reported in 2005, according to the Michigan Department of Community Health. This year, 41 outbreaks already have been reported, the agency said.

Outbreak of norovirus hits Rhode Island

Rhode Island is experiencing a general increase in cases of norovirus - a category of diseases similar to the stomach flu - but the University has not been affected.

The Rhode Island Department of Health uses syndromic surveillance to monitor the number of norovirus cases, tracking changes in levels of reported cases instead of counting individual cases. "There are reporting mechanisms in place with schools, nursing homes and emergency (medical) departments," said Annemarie Beardsworth, spokeswoman for the department. "They report back to the DOH an increase in the number of cases - they give a general summary."

"All those systems that report back to the DOH are seeing increased cases of norovirus at the same time," she added. "Normally what we expect at this time of year is a small cluster of an increase. What is significant this year is all those segments are reporting an increase at the same time."

State logs 130 norovirus outbreaks

Virginia Department of Health officials say there have been 130 norovirus outbreaks throughout the state since Nov. 1.

That includes 40 outbreaks in the central Virginia region. About 70 percent of the outbreaks have been in long-term care facilities. The highly contagious gastrointestinal illness causes diarrhea, vomiting and stomach cramps.

Two Richmond-area facilities -- Lakewood Manor retirement community and Beaufont Towers -- are recovering from outbreaks and expect to remove visitation restrictions soon.

The Hermitage, a retirement community on Westwood Avenue in Richmond, was not allowing visitors at its health-care center yesterday because of illness among residents, but staff did not yet have a confirmation of norovirus.

Health Officials Working to Stop Norovirus Outbreaks

More people than ever are becoming sick with the norovirus here in Michigan. The State Department of Community Health says 145 outbreaks were reported in Michigan in 2006. That's about four times the amount reported in all of 2005 when there were only 36 cases, and we could be on another record-breaking pace this year.

After only a month and a half into 2007, 37 outbreaks have already been reported. Local health agencies are working to prevent the spread of this virus. Health experts at Michigan State University say those numbers may still be on the low side.

Dr. Dele Davies, Pediatrics and Human Development at MSU: "We know for sure there are more people with the disease than what actually gets reported."

Norovirus plagues NMB school

The highly contagious virus that infected at least 190 people at North Myrtle Beach Elementary has been identified as a norovirus, an illness most people know from its cruise ship outbreaks.

Nearly 200 students and staff members stayed home sick on Friday, and the school will remained closed for most of this week for a thorough cleaning.

The S.C. Department of Health and Environmental Control announced the finding Sunday after analyzing stool samples from people who were infected.

Department spokesman Thom Berry said people often hear of norovirus outbreaks on cruise ships. There haven't been recent outbreaks in any other S.C. schools, but some were reported this year at several nursing homes and residential care facilities in the Upstate, he said.

Suspected food poisoning sickens 30

Michael Bates from the Hernando Today has reported that there has been a possible norovirus outbreak at Mallie Kyla's cafe in Brooksville, Florida.  Full story

BROOKSVILLE — A nasty outbreak of possible food poisoning hit at least 30 people and grounded several county staffers and government officials this past weekend after they attended a public workshop last Friday.

It is unclear how many residents who attended the workshop were affected.

County Health Department Environmental Manager Al Gray suspects the victims were hit with Norovirus, a food-borne illness that is highly contagious and can be spread by human contact.

300 now report illness after eating at Indianapolis Olive Garden

Commentary from the Associated Press

Three people have been hospitalized and more than 300 people claim they became ill after eating at an Olive Garden restaurant last weekend, a health official said Friday.

Also, six restaurant workers reported on Monday that they were feeling ill, said Marion County Health Department spokesman John Althardt. Olive Garden is based in Orlando.

"We're trying to isolate what the cause of the illness might be," he said.

The problem has been isolated to the Olive Garden on East 82nd Street on Indianapolis' north side, Althardt said.

Health officials have found no link to E. coli bacteria that sickened patrons at East Coast Taco Bell restaurants recently, Althardt said.

Health Service reports many students with suspected norovirus infections

Commentary By Madonna McDermott
Director, Student Health Service and Wellness Center

Full Story from the Bulletin Today at the University of St. Thomas

The University of St. Thomas Student Health Service reports many students with suspected norovirus infections.

This infection is often mistakenly referred to as the “stomach flu"; it is not related to the flu (influenza), which is a respiratory illness caused by influenza virus.

Noroviruses are members of a group of viruses called caliciviruses, also known previously as “Norwalk-like viruses.” Norovirus infection causes gastroenteritis, which is an inflammation of the stomach and the small and large intestines.

 

Are You at Risk for Norovirus Infection?

Here are some lessons on norovirus infections and some precautions to take in order to avoid becoming ill.

"You probably have never heard of the term Norovirus Infection, but it actually comes from contaminated food and water. It is especially important that you learn about this type of infection since there have currently been so many warning about contaminated food lately. The Norovirus Infection is actually one of the causes of acute gastroenteritis. Some of the symptoms that can occur with this virus are vomiting, stomach cramps, fever, dehydration and in most cases diarrhea. This is just one of the reasons why you should pay attention whenever there is any type of warning about contained food."

Talking with William Marler, Seattle attorney

29.sep.06
Puget Sound Business Journal (Seattle)
Clay Holtzman


For 13 years, Seattle attorney William Marler has made a name for himself as the E. coli lawyer. Food service companies, vendors and manufacturers fear him like bacteria fear penicillin. Marler was quoted as saying, "I hope so. We're really good at what we do."
The six-lawyer practice of Marler and Clark LLP specializes in suing producers and manufacturers accused of selling tainted food products. Its clients have received combined settlements and verdicts of more than $250 million. That includes the famous 1993 Jack in the Box E. coli case in Washington state.
Today Marler is tracking the nationwide outbreak of E. coli illnesses tied to bagged spinach. The outbreak has been linked to 183 illnesses in 26 states, according to The Wall Street Journal, including at least one death. Marler is representing 81 of those, including, he says, two deaths that have yet to be announced.

SAN FRANCISCO -- Despite the recent E. coli spinach outbreak, food may be safer now than at any other time in the last decade, with illness occurring at record-low rates, new federal statistics show.

Consumers get part of the credit, for handling food more safely at home, but experts say the biggest improvement came from better industry controls and inspections.

"The food is actually cleaner to begin with," said Dr. Robert Tauxe, top food scientist at the federal Centers for Disease Control and Prevention. Certain germs have dramatically declined, and "that to me is really solid progress."

However, the trend could reverse in coming years if fruit and vegetable growers do not address problems like those that led to the spinach scare, Tauxe and others said.

Regulating food handling is key to safety

Weld County, Colorado

September 26, 2006

Norovirus:

« Is commonly referred to as the cruise-ship virus or the 24-hour stomach flu.

« Commonly described symptoms are explosive vomiting and diarrhea.

« Can be an air-borne illness or food-borne illness.

« Is linked to an estimated 23 million cases of acute gastroenteritis and more than 50 percent of food-borne illness, according to the Centers for Disease Control.

« Is passed through food by poor hand-washing, not improper cold and hot holding of foods. The use of gloves or suitable utensils (tongs, spatulas, etc.) is recommended to prevent unnecessary bare-hand contact with food. Good hand washing involves using soap and water and washing for at least 20 seconds. Hand sanitizers may only be used in addition to good hand washing.

A hundred students in Austria hit by severe stomach flu

Friday • September 22, 2006

About 100 high-school students in Austria are in hospital with severe stomach flu following an outbreak blamed on a virulent strain of norovirus, according to local medical authorities cited Friday by the APA news agency.

The students and one teacher at a commerce school in the town of Eisenstadt were struck Thursday afternoon by intense bouts of vomiting, diarrhea and stomach cramps, and were treated in eight different hospitals in the region.

Authorities have traced the outbreak to roast chicken served in the school cafeteria, but have excluded salmonella -- at first thought to be the culprit -- as the cause.

No one suggesting people not eat fruits and veggies

By Stephanie Dunnewind
Seattle Times staff reporter
California organic-food company linked to widespread E. coli scare

With the recent Food and Drug Administration (FDA) warning about the link between the E. coli outbreak and bagged spinach, consumers may start to wonder about the safety of everything in their refrigerator produce drawer. Here are answers to some questions that might arise.

Q: Can I just wash bagged spinach?

A: No. The bacteria are too tightly attached. "If you wash it, it is not going to get rid of it," Robert Brackett, director of the FDA's Center for Food Safety and Applied Nutrition, told The Associated Press. The safest thing is to toss it out.

Q: So, what about unpackaged spinach?

A: The FDA's warning applies only to bagged spinach.

Nationwide, many groceries are pulling all packaged spinach and salad mixes containing spinach from the shelves. Whole Foods Market is temporarily removing all fresh spinach — bagged or otherwise — "just to be on the safe side," said spokeswoman Ashley Hawkins.

At Seattle-area farmers markets, farmers will still sell their locally grown spinach and answer any consumer questions, said Karen Kinney, associate director of the Neighborhood Farmers Market Alliance.

Q: How are vegetables and fruits contaminated?

A: In other foodborne-illness outbreaks, factors included manure used as fertilizer; exposure to dirty floodwater; poor agricultural water quality; presence of animals in fields or packing areas; and the health and hygiene of workers handling produce during production, packing, distribution or preparation.

Park conditions could pose health risk

Alamogordo Daily News
By Jeff Stevens, Assistant Editor

The residents of Mountain View Trailer Park have been without water or bathroom facilities for 10 days, and until now have suffered alone. However, the situation has lasted long enough that the unsanitary living conditions could pose a health risk for the entire community.

"The question I have is, is it possible if people are allowed to stay there, without water, could this lead to a Typhoid Mary situation," asked District 4 Commissioner Steve Brockett, whose district includes the Mountain View Trailer Park. "I'm real concerned about that."

And the answer to Brockett's question is, "yes." It is possible that conditions at Mountain View Trailer Park could pose a health risk for all of Alamogordo.

DOCTORS and nurses could face the sack for not washing their hands at a Greater Manchester hospital.

The move at Tameside General is part of the latest efforts to tackle the deadly MRSA superbug and follows a visit from a government hit squad.

In future, staff will be legally obliged to wash their hands regularly.

MRSA experts have recommended that clinical and administration staff who regularly visit wards have `infection prevention and control responsibilities' written into their job descriptions.

What is Norovirus?

From www.about-norwalk.com

Norovirus (previously called "Norwalk-like virus” or NLV) is a member of the family Caliciviridae. The name derives from the Latin for chilice—calyx—meaning cup-like, and refers to the indentations of the virus surface.

Nature has created an ingenious bug in Norwalk. The round blue ball actually is a protein surrounding the virus's genetic material. The virus attaches to the outside of cells lining the intestine. Then it transfers its genetic material into that cell. There it reproduces, finally killing the human cell to release new copies of it that attach to more cells of the intestine's lining.

The family of Caliciviridae consists of several distinct groups of viruses that were first named after the places where outbreaks occurred. The first such outbreak occurred in 1968 among schoolchildren in Norwalk, Ohio.  The prototype strain was identified four years later, in 1972, and was the first virus identified that specifically caused gastroenteritis in humans. Id. At S255. Other discoveries followed, with each strain named based on the location of its discovery-location, e.g., Montgomery County, Snow Mountain, Mexico, Hawaii, Parmatta, Taunton, and Toronto viruses. A study published in 1977 found that the Toronto virus was the second most common cause of gastroenteritis in children.

Eventually this confusing nomenclature was resolved, first in favor of calling each of the strains a Norwalk-like virus, and then simply, a norovirus – the term used today.

Noroviruses are estimated to cause 23 million cases of acute gastroenteritis in the United States per year, and are the leading cause of gastroenteritis in the United States.  Of viruses, only the common cold is reported more often than viral gastroenteritis (norovirus).

The norovirus is transmitted primarily through the fecal-oral route and fewer than 100 norovirus particles are said to be needed to cause infection.  Transmission thus occurs either person-to-person or through contamination of food or water. Foodborne norovirus transmission often occurs when food is contaminated by an infected food handler.  The virus is shed in large numbers in the vomit and stool of infected individuals, most commonly while they are ill. Some individuals may, however, continue to shed the norovirus long after they have recovered from the illness.  Aerosolized vomit has also been impacted as a mode of norovirus transmission.

In short, and as noted by the CDC in its Final Trip Report, “[n]oroviruses can cause extended outbreaks because of their high infectivity, persistence in the environment, resistance to common disinfectants, and difficulty in controlling their transmission through routine sanitary measures.”


Small bugs on ships make big waves

Despite disinfection and inspection, nasty germs such as norovirus sometimes stow away
Sunday, September 10, 2006

The Oregonian

Stormy seas are known to turn the stomachs of cruise passengers, but another culprit can send passengers heaving to the rails.

The microscopic norovirus or one of its cousins does so to thousands of cruise passengers each year.

Cruise industry representatives note that most people don't get sick. The International Council of Cruise Lines reports that out of the more than 8 million North American passengers in 2005, fewer than 1 percent contracted norovirus aboard ships, compared with an estimated 8 percent of the U.S. population who contracted a virus on land.

Ships are disinfected routinely and regularly inspected by vessel sanitation experts from the U.S. Centers for Disease Control and Prevention.

Still, germs sometimes stow away, and the small bugs can have a big impact.

Norovirus

When the word “food pathogens” is mentioned, most will people will associate it with salmonella, E.coli or listeria. Although they are true pathogens, the symptoms they produce are initially similar to a common gastro virus called the norovirus. Viruses are very different from bacteria and parasites. They are not affected by treatment with antibiotics, and they cannot grow outside of a person’s body.

You see, the norovirus is a very common virus that causes nausea, vomiting, diarrhea, and some stomach cramping. Sometimes people also have a low-grade fever, chills, headache, muscle aches, and a general sense of tiredness. The illness often begins suddenly, and the infected person may feel very sick. The illness is usually brief, with symptoms lasting only about 1 or 2 days. In general, children experience more vomiting than do adults. Most people with norovirus illness experience both diarrhea and vomiting.

The main concern is that sometimes people become dehydrated due to vomiting and diarrhea and may need special medical attention. Dehydration problems are usually only seen among the very young, the elderly, and persons with weakened immune systems.

Infection with noroviruses

Noroviruses are found in the stool or vomit of infected people. People can become infected with the virus in several ways, including:

• Eating food or drinking liquids that are contaminated with norovirus;
• Touching surfaces or objects contaminated with norovirus, and then placing their hand in their mouth;
• Having direct contact with another person who is infected and showing symptoms

Persons working in day-care centers or nursing homes should pay special attention to children or residents who have norovirus illness. This virus is very contagious and can spread rapidly throughout such environments. Particular care should be taken with young children in diapers who may have diarrhea or who have vomited as both stool and vomit can carry the virus.

People infected with norovirus are contagious from the moment they begin feeling ill to at least 3 days after recovery. Some people may be contagious for as long as 2 weeks after recovery. Therefore, it is very important to use good hand washing and other hygienic practices.

Treatment for people with norovirus infection?

Currently, there is no antiviral medication that works against norovirus and there is no vaccine to prevent infection. Norovirus infection cannot be treated with antibiotics because antibiotics work to fight bacteria and not viruses.

Four outbreaks of norovirus gastroenteritis after consuming raspberries, Sweden, June-August 2006

Are you safe on a cruise ship?

9/7/2006
By Erica Silverstein, SmarterTravel.com


Disturbing tales about cruise vacations are more common than we'd like. Numerous passengers have disappeared from cruise ships, including George Smith IV, whose family is currently suing Royal Caribbean. The Crown Princess tilted sharply on one of its first voyages, injuring dozens of guests, and the Star Princess caught on fire, destroying balconies on several decks. Last year, modern-day pirates attacked a Seabourn ship off the coast of Somalia.
All of these scary incidents lead holidaymakers to wonder: Am I safe taking a cruise vacation?

The answer is a conditional yes. In today's uncertain world, you can never be completely safe anywhere. Going on a cruise does not put you in greater peril than does any other vacation. But, the responsibility ultimately falls to you to protect yourself and your interests while onboard.

MARQUETTE ó A recent outbreak of a norovirus-like illness in Marquette County has Marquette County Health Department officials advising residents to take precautions.

Marquette General Hospital and the health department have received increased reports of sudden nausea, vomiting and diarrhea. While a specific cause has not been determined, the symptoms and the easily contracted nature of the outbreak suggests a ìnorovirus-like illness,î according to a health department press release.

ìThe first indication we had was a call from Marquette General where they were seeing more people coming through the emergency room (with the symptoms). Some of the people coming to visit out-patients at the hospital were also exhibiting symptoms. Shortly thereafter some of the employees at the hospital got sick,î said Dr. Randall Johnson, director of the health department.

Health service warns of gastro outbreak at Maitland Hospital

Wednesday, 23 August 2006

People are being urged to put off visiting patients in the medical and high dependency units at Maitland Hospital this week due to an outbreak of viral gastroenteritis.

The hospital has introduced strict infection control measures to minimise the spread of the bug, which is believed to have been caused by the highly infectious norovirus.

Hunter New England Health says the virus can spread easily through direct contact with an infected person or contaminated surfaces.

Symptoms include vomiting, diarrhoea, fever, abdominal pain and headache.

School Food Safety Facilities Lacking

AUGUST 17, 2006

After suffering the worst-ever mass food poisoning incident in Seoul, Incheon and Gyeonggi, the Ministry of Education and Human Resources Development inspected school meal facilities and food cleanliness in 9,186 elementary, middle and high schools nationwide last month. According to the result released on August 16, many schools were not equipped with a sanitary system, heightening the possibility of another food poisoning incident.

The result showed that among 8,024 schools (87.4%) that run their own school lunch programs, and 1,161 (12.6%) schools that have school meal providers, 6,982, or 76 percent, did not have a closed room where food ingredients are washed and sterilized. Nor did they have a separate cook room and a washing room, a circumstance where foods are highly likely to be contaminated.

It's that simple ó wash your hands

Yakima Herald Republic
August 17, 2006

Have you hugged a stranger today?

Public health experts don't find that an odd question. In fact, it may be a rallying cry in the event of a pandemic influenza.

They certainly won't be advocating a handshake, which they clearly view as public enemy No. 1 ó especially if the widespread threat of the Avian flu strain, which has killed millions of birds and more than 100 people since 1997, becomes a reality.

In a public health forum in Yakima last week, the state's top health officer reinforced the message that experts (along with your mother) have been saying for years when it comes to stopping the spread of disease: Wash your hands. This simple task is vitally important when facing the potential ravages of a worldwide outbreak of influenza such as the Avian flu. Experts predict such a pandemic could cause more than 200,000 deaths nationwide and at least 5,000 in our state alone, with thousands requiring hospital stays and outpatient visits.

Officials Say Dirty Well Caused Campers' Illnesses

(AP) BALTIMORE Harford County health officials say a contaminated well at Broad Creek Memorial Scout Reservation sickened as many as 200 campers last week.

Health officials say they were concerned that the camp did not report the outbreak.

Samples from the well tested positive yesterday for fecal coliform bacteria.

The campers are part of the International Jamboree for Boy Scouts of Polish descent.

They were infected with Norovirus. That's a highly contagious gastroenteritis, seen commonly on cruise ships.

Doctor Andrew Bernstein, Harford County's health officer, says it is spread easily between people and lasts one to two days.

The camp has played host to about 1,200 of Polish descent for the past two weeks.

The scouts had come from across the United States and around the world.

The Korea Centers for Disease Control and Prevention was cited as saying yesterday it had failed to determine which foodstuffs carried the virus that sickened thousands of children in June.

Huh Young-joo, the center's chief investigator, was quoted as saying, "The cause of the outbreak was a norovirus, but it was technically difficult to prove which food carried the virus."

According to Mr. Huh, seasoned sesame leaves, which were imported from China, were assumed to have carried the virus, but it was impossible to extract the virus from the food products.

In June, 2,872 students in the Seoul area exhibited symptoms of food poisoning after eating at 32 school cafeterias, many of which were run by CJ Food System, the country's largest food catering company.

In the aftermath of the outbreak, the company said it would close its school meal business and donate the cafeteria facilities to schools.

In late June, the National Assembly hurriedly passed a bill requiring elementary, middle and high schools to run their own cafeterias rather than using outside caterers.

A summer camp in Alexandria remains closed this week because of a Norovirus outbreak that sent campers home early. Last week about 150 of the 570 campers at senior teen camp at lake geneva Christian center showed symptoms, including vomiting, diarrhea and stomach cramps. Ten people were treated at the hospital in Alexandria. The camp director says the food supply has been ruled out as a source of the illness. But he says the buffet style of serving food did contribute to its spread. The camp will be closed through the end of this week while every single surface is wiped down.

Bible Camp Shut Down After Norovirus Outbreak

(AP) Alexandria, Minn. A Bible camp in Alexandria, Minn. has been temporarily shut down because of a norovirus outbreak.

People attending the Senior Teen Camp at Lake Geneva Christian Center have been sent home a day early with instructions on how to prevent further spread of the gastrointestinal illness.

State Health Department spokesman Doug Schultz says officials took the precaution after a significant outbreak of the norovirus among teenagers at the camp.

He says about 150 out of 570 campers showed symptoms, including vomiting, diarrhea and stomach cramps.

Health officials haven't determined how the outbreak began.

Schultz says the camp will remain closed until all surfaces are thoroughly cleaned.

Update on Norovirus


Last updated: Friday, August 04th, 2006 08:15:54 PM

The Norovirus has now infected 162 people in Kittitas County.

That's according to workers at Kittitas County Public Health. They have not received any new cases as of Friday (8-4-06) which could mean two things, either fewer people are being infected, or fewer people are reporting their symptoms.

The virus causes nausea, vomiting and diarrhea. To avoid becoming sick you should avoid contact with an infected person or surfaces they have touched. As always, be sure to wash your hands with soap and water.

Wrangell identified as site of suspected norovirus deaths

A Wrangell long term care facility has been identified as the site of three suspected norovirus deaths. Brian Gilbert -- CEO of the Wrangell Medical Center -- says the facility is back to normal now. Gilbert says admissions and discharges were halted to contain the outbreak. He adds that the problem was prevalent throughout the community.

It's state policy not to reveal the names of the facilities or their locations. Health officials say the outbreak started in late June when a staff member got sick, followed by 16 others falling ill.

Three men -- all residents -- died within three days of being hit with the gastrointestinal illness.

CHEYENNE, Wyo. - Health officials say fecal matter contaminated the water supply at a Bible camp where more than 100 people fell ill with gastrointestinal illnesses.

The Wyoming Health Department reported Tuesday that it found both viral and bacterial infections in camp-goers, some from North Carolina. Nine cases of norovirus have been confirmed by lab tests, along with six cases of Campylobacter jejuni, a bacterial infection; three people were found to have both infections.

More than 300 people attended Camp Grace, near Wheatland in northern Albany County, between mid-June and mid-July, when the camp was closed and the investigation into the illnesses began. Of the 175 camp-goers interviewed by the Health Department, 88 reported some form of gastrointestinal illness since attending the camp. Another 20 people who did not attend the camp, but who have a family member that did, have also become sick.

The Food and Drug Administration on Monday warned all U.S. residents to avoid eating raw oysters from the Pacific Northwest, the center of a big outbreak of food poisoning.

The federal warning follows a Washington state ban on harvesting oysters in parts of the Hood Canal and Puget Sound, some of the country's richest oyster beds.

Those actions will make it a little harder for consumers to find raw oysters, though many markets and restaurants still offer the delicacies. But they are significantly hurting shellfish harvesters, especially Washington's oyster industry, the biggest in the nation.

Caribbean Cruise Ship Serves 227 Sick Passengers Royal Norovirus, Could Be Sued

July 31, 2006

A Royal Caribbean cruise ship is to blame for the illness of 221 passengers and six of its 12-hundred crew members aboard it. The ship just docked in Port Canaveral and included stops in the Bahamas, Virgin Islands and St. Maarten.

Sick passengers started complaining of vomiting and diarrhea Wednesday and were treated with over-the-counter medications.

One of the passenger has been contemplating a law suit to compensate her for the time she fell ill.

This is the second outbreak aboard the Mariner of the Seas this year. In January, the ship reported a norovirus that sickened 276 passengers and 27 crew members.

Noroviruses affect about 23 million Americans annually, and 16 incidents of the illness have been reported on cruise ships so far this year, according to the Centers for Disease Control.

It is very likely that this company will be sued.

Classes are expected to be back to normal at Waialua High School tomorrow following an outbreak of a flu-like norovirus that left the school short of teachers and staff on Friday, the first day of the new school year.

About two dozen teachers and staff members attending a preschool retreat at nearby Camp H.R. Erdman on Thursday complained of the illness, whose symptoms include upset stomach, diarrhea, vomiting and fever, said Department of Education spokesman Greg Knudsen.

By Friday, many of the teachers and staff could not report to work. That forced many teachers who did report to double up on teaching assignments and caused some students to be assigned to the cafeteria for the day, Knudsen said.

The cause of the viral outbreak has not been determined, he said.

"It usually takes about two to three days to run its course, so we expect most people to be back to work on Monday," Knudsen said.

Smooth sailing: 'cruise ship virus' tackled by UH, Baylor College of Medicine

18.jul.06
University of Houston Media Release

Houston -- You're on vacation, having fun sailing the seven seas, when your stomach starts rolling worse than the waves. Before you know it, nausea and vomiting have replaced shuffle board and sun-bathing.

Unfortunately, it's a scenario that's becoming increasingly common on cruise ships. So common, in fact, that the National Institutes of Health's Western Regional Center of Excellence (RCE) for Biodefense and Emerging Infectious Diseases awarded a two-year $280,000 grant to a pair of University of Houston professors who are studying what has commonly been dubbed the "Cruise Ship Virus."

This RCE is part of a national network of 10 other centers that support research focused on countering threats from bioterror agents and emerging infectious diseases. Each is comprised of a consortium of universities and complementary research institutions serving a specific geographical region. UH and the Baylor College of Medicine (BCM) are part of region VI, encompassing institutions in Texas, New Mexico, Oklahoma, Arkansas and Louisiana.

A popular Toledo eatery is being investigated as the likely source of a food-borne illness from contaminated potato salad that left as many as 100 people sick.

Nick & Jimmy's Bar & Grill, 4956 Monroe St., catered a June 15 graduation party in the Bowling Green area, after which people became ill.

The Ohio Department of Health is investigating the complaint with the help of the Toledo-Lucas County and the Wood County health departments.

Amy Jones, communicable disease nurse for the Wood County health department, said yesterday that potato salad served at the gathering tested "fairly high for fecal coliform."

Dr Greg Simmons, Auckland District Health Board

The New Zealand Food Safety Authority (NZFSA) is reminding people not to consume uncooked oysters imported from Korea. All bags of frozen Korean oysters are clearly labelled as requiring to be cooked before consuming. This product is known to sometimes carry norovirus, which causes a gastrointestinal illness.

The Korean oysters are packed frozen in 1kg bags and distributed throughout New Zealand, and labelled, as is required by the current import health standard, with a statement that the product must be cooked or must not be eaten raw.

They must be cooked in such a way that the centre of the oyster reaches 90?C and is held at that temperature for 90 seconds. NZFSA also reminds chefs and consumers using the product to take particular care with hand and kitchen hygiene, particularly when defrosting, to ensure that other foods are not cross-contaminated with raw oyster juice.

Summer Travel Season Increases Incidents of Foodborne Illness

Wednesday July 5,
Proper Procedures in the Kitchen and Knowledgeable Restaurant Patrons can Make a Difference

CINCINNATI, July 5 /PRNewswire/ -- As warmer weather and summer travel swing into full force, so do cases of foodborne illness, according to the USDA's Food Safety and Inspection Service. The busy summer travel season can make it difficult for restaurant kitchen staff members to keep up with the many details of food safety -- and a slip up in this area can compromise the health of customers, which in turn can lead to a big hit on a restaurant's bottom line.

"Maintaining a sanitary environment, in both production and service of foods, is key to protecting the health of guests," said Chef Steve Browe of Paul's 5th Avenue in Grandview Heights, Ohio, just west of downtown Columbus. "A foodborne illness outbreak is the deepest nightmare of a restaurant operator. Ultimately, an outbreak can ruin a business, first by reducing the daily number of people who frequent the operation, and in time, by building a negative general impression through word of mouth."

Sickness bug liner back in port

July 5, 2006

Operators of a cruise liner hit by a major outbreak of a sickness bug twice in a month have vowed to carry out even more stringent deep cleaning measures.
The Black Prince returned to Leith early on Wednesday after about 100 of the 393 passengers fell ill.

They are thought to be suffering from a vomiting bug similar to the Norovirus which hit 136 passengers on the Fred Olsen vessel at the start of June.

The company said even more stringent disinfecting would now take place.

Passengers have been disembarking from the liner and an environmental health team from Edinburgh City Council is on board to begin investigations.

Stomach virus makes appearance

By ERICA KOLASKI
Tribune Staff Writer

CHEBOYGAN, MI - The local Health Department has issued a warning to Northern Michigan residents that norovirus gastroenteritis, a nasty stomach virus, is on the rise in Michigan.

According to Cathy Goike, a public health educator with District Health Department No. 4, norovirus, formerly named Norwalk virus, causes a moderate illness which typically includes nausea, vomiting, diarrhea and cramps.

She said that during the season of graduation parties, family reunions and Fourth of July picnics, residents should be aware of the potential for the ailment.

ìNorovirus is easily transmitted through food, by person-to-person contact, or by contaminated surfaces,î said Goike. ìOutbreaks of Norovirus-like viruses have been associated with both food and water.î

It's usually not serious, but it can be incredibly uncomfortable for a couple of days.

The Missoula City-County Health Department has confirmed that norovirus - you'd most likely refer to it as ìstomach fluî - is going around Missoula.

More than 2,000 people in Billings have been sickened by it recently.

Symptoms include nausea, vomiting and/or diarrhea. It rarely lasts more than a day or two and there are no lasting effects.

However, the violent vomiting and diarrhea can lead to severe dehydration, the treatment of which sometimes requires hospitalization.

Authorities fail to find root of food poisoning

The Korea Herald
June 30, 2006

Health authorities have failed to identify the cause of a recent mass food poisoning, making it difficult to hold the nation's largest food supplier responsible for the incident.

Public health authorities said yesterday that they were still unable to determine the route of infections of the norovirus, which allegedly led to the outbreak. The highly-infectious virus is transmitted either person-to-person or through contaminated food and water.

Consequently, officials say they may have difficulty in taking administrative and legal action against CJ Food System which provided food and operated cafeterias at most of the schools affected by the incident. The massive outbreak of food poisoning hit 40 schools and sickened more than 3,000 students since June 16.

Oysters responsible for rugby gastroenteritis

29 June 2006

Oysters were to blame for the hundreds of corporate rugby fans struck down with food poisoning at the All Blacks-Ireland rugby test at Eden Park almost two weeks ago.

Auckland Health officials said the outbreak of gastroenteritis was "strongly associated" with the consumption of imported raw Pacific oysters on offer in various hospitality suites at the game.

The Auckland Regional Public Health Service (ARPHS) has been investigating the source of the norovirus infection, a common cause of gastroenteritis.

The investigation by the Auckland Regional Public Health Service (ARPHS) into the cause of the Eden Park gastroenteritis outbreak is progressing.

The cause of illness among patrons at the match has been confirmed following testing by the Institute of Environmental and Scientific Research (ESR) as norovirus. Norovirus is highly infectious gut virus that can be spread directly from person to person through vomiting or touch contact, or through eating contaminated food. Symptoms are predominantly vomiting and diarrhoea which usually last approximately 48 hours.

Interviews have been conducted on 407 patrons. Of those, 81 (20%) have reported illness. Of the four affected hospitality areas investigated the rate of illness was highest for the Hall of Legends where 36% of the 178 interviewed patrons were ill.

Companies wake up to food handling risk

Press Release: Compass Group
News Release
For immediate release

New Zealand is quick to boast of its world-beating position in everything from enterprise to extreme sports, but there's one area where we'd rather not talk about our performance at all. New Zealand holds the unenviable position of food-poisoning capital of the developed world, with rates so far in excess of comparable countries that experts are at a loss to explain it.

Auckland medical officer of health, Greg Simmons, says the cost of this level of foodborne illness to the New Zealand economy is enormous, with some $60m in medical costs and lost productivity annually.

Several hundred people were taken ill as a result of suspected norovirus infection after eating at Eden Park during the second All Blacks test match against the Irish earlier this month, and well over 15,000 of us fell victim to Campylobacteriosis ñ a nasty bout of nausea and diarrhoea accompanied by muscle pain, fever and headache ñ alone in the last 12 months, over three times the infection rate in Australia and the United States.

Last month, the Greenville area experienced what may have been one of the largest outbreaks of a primarily food-borne illness the state has ever seen.

But beyond the at least 127 who got sick at a tennis tournament there, few outside Greenville have heard about the outbreak of what state Department of Health officials think was Norwalk virus, an illness that causes diarrhea and vomiting and is spread through fecal to oral contact.

On May 6, most of the 500 participants at the Mississippi State Tennis Association's State Seniors Championship attended a luncheon. The next day, seemingly all at once, dozens of them got sick, according to tennis players who became ill.

Dr. Ed Hill, president of the American Medical Association, speaks with Gov. Haley Barbour before a health summit. Hill said he wondered why he wasnít receiving morbidity reports from the Health Department regularly.

The same state Department of Health appointed to protect the public may now be endangering the public by failing to adequately warn Mississippians about disease outbreaks and health hazards, a four-month investigation by The Clarion-Ledger has found.

A recent outbreak of the Norwalk virus, the leading cause of foodborne disease in the United States, left at least 127 Mississippians sick. The department did not inform the public of the worst outbreak of foodborne illness in Mississippi in recent years, and the disease spread to others.

Jackson County's public and private schools serve meals to thousands of children each day. It's hard to find a group of diners with more sensitive stomachs.

But because schools are open nine months of the year, they get the same scrutiny as a seasonal ice-cream stand.

Schools are inspected randomly just once a year. Commercial and year-round operations are visited by health inspectors twice.

"That's inexcusable," said Caroline Smith DeWaal, who is food-safety director at a Washington, D.C., consumer watchdog organization. "The people who experience the most severe foodborne illnesses are the elderly and children.

After about 1,700 students showed symptoms of food poisoning at 25 schools in the capital region over the last week, the Education Ministry yesterday ordered CJ Food System, the nation's largest caterer, to suspend its meal programs at 93 schools around the country.

CJ said in a statement on its Web site that it had offered institutions where it runs cafeterias and the 1,700 caterers that purchase its food supplies the option of suspending those services temporarily. A CJ spokesman told the JoongAng Ilbo yesterday evening that 114 of 536 cafeterias had accepted that offer. Five were offering only partial menus of products not likely to be contaminated; 16 were still in negotiations and 401 had taken no action.

Four years ago, the state agreed to equip a new state-of-the-art lab in Allegheny County that would test for deadly diseases such as anthrax. Delays securing money for the $4 million lab and problems with selecting an appropriate location delayed construction.

Viral outbreaks on cruise ships are a recurring problem for the industry. And now a Hawaii-based ship has had its first reported exposure. Sixty passengers spent part of their vacation in quarantine last week aboard the Pride of Aloha.

To a traveler, a cruise ship may look like paradise. To one scientist, it's more like a petri dish for illness.

"People are mixed very closely with others, so it's very easy to transmit disease through contact, air, and just sort of the environment," said Dr. Alan Tice, a University of Hawaii infectious disease specialist. "Some viruses potentially have an ability to sort of stick or attach to people that's fairly extraordinary."

With summer approaching, many people seek recreational activities on local waterways or backyard pools. Benton County Environmental Health officials encourage swimmers to practice healthy behaviors to prevent water illnesses.

Recreational water illnesses are spread by swimming in water contaminated as a result of poorly maintained recreational water venues, the presence of chlorine-resistant germs, or runoff-related contamination of lakes or beaches.

ìTemporary pools that are not properly disinfected and are used by a large number of people are a special concern, especially since the number of Norovirus outbreaks are on the rise in the state,î said Bill Emminger, environmental health deputy administrator.

Virus runs rampant on cruise ship

SOUTHAMPTON, England, June 3 (UPI) -- A virus infected 200 individuals on a Princess Cruises ship this week off Britain, forcing the ship to return prematurely to shore.

Carnival UK, the parent company of the cruise line, has offered all passengers a 30 percent refund.

The Independent reports most infected individuals were forced to stay in their rooms during their trip and that the crew was ill-equipped for the outbreak.

"What is of greater concern is the admission by Princess Cruises that the boat had seen a similar outbreak on the last two days of its previous cruise," said Suki Chhokar, a travel lawyer.

A Carnival UK spokeswoman said the outbreak of norovirus caused acute gastroenteritis. She said the ship was being sanitized to avoid future incidents.

Not that you'd want to, but if you had to construct a worst-case scenario for a foodborne illness outbreak in a full-service restaurant, you'd have to go some to top the one that befell the East Lansing, MI, unit of casual white tablecloth chain Bravo Cucina Italiana. It didn't just suffer an outbreak of norovirus just months after one befell direct competitor Carrabba's Italian Grill at its Lansing-area unit. Worse, one of Bravo's victims was the professor who's in charge of Michigan State University's food safety program. And, yes, she's filing suit.

We don't know that the suit filed on behalf of Pattie McNeil, adjunct professor at Michigan State's School of Hospitality Business, will be successful, or even that it will make it to court. But if it does, the attorneys defending Bravo will have one tough time finding impartial jury members. Lansing and East Lansing, MI, home of Michigan State University, have been scenes of two very large outbreaks of foodborne norovirus this year.

Nearly 500 holidaymakers were offered refunds yesterday after a cruise to the Norwegian fjords was cancelled because of an outbreak of winter vomiting disease on board the ship they were due to sail on.

The MV Van Gogh was due to leave on a seven-day trip to Norway on Sunday night, but travellers were turned away at the dock after an outbreak of norovirus, which causes diarrhoea and projectile vomiting. A spokesman for Travelscope Holidays said the bug was probably brought on board by a passenger on the previous trip.

Two elderly passengers were removed from the ship on stretchers and taken to Colchester hospital when it docked in Harwich, Essex, on Sunday. Both people, who were in their 80s, have since been discharged. The illness struck down 70 passengers and 15 of the crew on the ship's previous voyage, also a Norwegian cruise.

Number of norovirus cases increasing across Florida

May 26, 2006

Across Florida ñ Health departments across Tampa Bay and the state are seeing an increase in suspected norovirus cases. The illness is common this time of year but officials say there are more than usual. Symptoms of norovirus usually include nausea, vomiting, diarrhea and some stomach cramping. Sometimes people additionally have a low grade fever, chills, headache, muscle aches and a general sense of tiredness. The illness often begins suddenly and the infected person may feel very sick. Norovirus is usually brief, with symptoms lasting only about one or two days. In general, children experience more vomiting than adults. Most people with norovirus illness have both of these symptoms.

To avoid contracting norovirus, the center for disease control recommends washing your hands frequently. Carefully wash fruits and vegetables and steam oysters before eating them. Clean and disinfect contaminated surfaces immediately after an episode of illness using bleach. Immediately remove and wash clothes or linens that may be contaminated.

Over the last two months, it may have seemed that everywhere you went, you learned of someone who had become ill with norovirus or had Norwalk-like symptoms. Since the virus made its presence known in our community at the end of March, the Yellowstone City-County Health Department has received reports from approximately 1 percent of our population who have experienced the signs and symptoms of this hardy little virus.

According to experts at the federal Centers for Disease Control and Prevention, these reports are probably a small sampling of the actual numbers of ill people in the community.

Agency warns against eating shellfish from private piers

May 11, 2006
Maryland Department of the Environment

The growing proliferation of home based aquaculture projects and oyster gardens has lured some to eat the shellfish grown for water quality improvement initiatives. Due to the potential presence of pathogens, officials at the Maryland Department of the Environment (MDE) urge oyster growers against doing so.

Shellfish are filter-feeding organisms; they strain the surrounding water through their gills which trap and transfer food particles to their digestive tract. If the water they are housed in is contaminated with disease-causing organisms, these organisms are also trapped and consumed as food. Because shellfish pump large quantities of water through their gills each day, even low concentrations of harmful organisms from the waters can reach dangerous levels in the shellfish. If shellfish containing these organisms are eaten raw or partially cooked, illness may result.

INDEPENDENCE, Mo. -- A group of residents at a Jackson County retirement complex became sick this week with a stomach bug, KMBC's Micheal Mahoney reported Friday.

Several residents at the Fountains at Greenbriar started feeling ill on Monday. When the stomach virus spread, Greenbriar officials canceled the week's activities, including laundry services, and they closed the dining room. Instead, the 226 residents had their meals delivered to their apartments.

"That keeps people from gathering together. When you have people who live in a facility like this, they normally do their meals in the dining hall," said Larry Jones, with the Independence Health Department.

GRAND RAPIDS -- A sandwich-shop worker vomited, but felt better later that morning and returned to work.

He had norovirus, which causes stomach cramps, diarrhea and vomiting. Soon, he wasn't the only one sick to his stomach. His illness spread to 100 others who ate lunch catered by the now-closed Blimpie restaurant where he worked.

The national Centers for Disease Control and Prevention highlighted the case in its Morbidity and Mortality Weekly Report released Thursday. It detailed Kent County Health Department's efforts to identify the source of the virus and suggestions to prevent food-borne illnesses from spreading.

The virus is very contagious, and spreads through contact with contaminated surfaces and objects.

WASHINGTON - A single employee of a sandwich chain who came back to work too early after suffering from a stomach virus infected more than 100 office workers who ate party-sized submarine sandwiches last year, federal health officials reported on Thursday.

The U.S. Centers for Disease Control and Prevention said the man passed a norovirus on to three separate office parties in Kent County, Michigan in May last year.

And it took a week for the restaurant to be closed and properly disinfected afterward, the CDC said in its weekly report on death and illness.

"Illnesses at a publishing company, school, social service group, and among members of the public resulted in closure of a warehouse, employee absences, pay for substitute teachers, loss of wages, and loss of revenue to the restaurant during a week-long closure," the CDC report reads.

Flu outbreak kills 2 seniors at Vancouver facility

04:07 PM PDT on Thursday, April 6, 2006
By KRISTINA BRENNEMAN, kgw.com Staff

VANCOUVER, Wash. -- An outbreak of stomach flu killed two elderly residents at the Cascade Retirement Inn in Vancouver Thursday.

The two were among those taken to the hospital Tuesday, the same time when the norovirus sickened 46 other residents and staff at the facility.

Those who fell ill range in age from 60 years to 100 years old, said Risa Johnson, a spokeswoman for the Clark County Health Department.

At least eight others have been hospitalized, health officials said.

Johnson said it is "unusual" to have this large of an outbreak. It's more severe because it is in elderly adults."

The Clark County Health Department is investigating the deaths, which will include a look at the assisted living facility's food service, Johnson said. Health officials will talk about the outbreak at a Thursday afternoon news conference.

Norovirus, a type of illness similar to that spread on cruise ships, produces symptoms of nausea, vomiting, fever, and diarrhea.

ìAlthough most adults typically recover from norovirus within 24 to 48 hours, symptoms can be more severe in elderly adults, especially those with other underlying medical conditions. We suspect thatís the situation here,î said Marni Storey, Clark County's Public Health Services Manager. ìWe are saddened by the deaths of these residents and extend our condolences to their loved ones.î

Because the outbreak has affected the entire facility, no visitors are being admitted, Johnson said. The facility has closed both dining rooms and is serving meals to residents in their rooms.

And the facility has been decontaminated, Johnson said.

She said there are no plans to evacuate the remaining residents at this time.

As an undergraduate 25 years ago, and once my girlfriend showed me how to get at the theft-proof rolls in the university centre, the supplies of toilet paper in our household became one less student expense.

My hockey bag is still filled with those little soaps and shampoos from hotel rooms around the globe.

I was the kind of student -- and apparently I'm not alone -- University of Guelph administrators in Canada were worried about when they say that residence students should provide their own handwashing soap.

About a year ago, the university switched to sanitizers instead of soap and paper towels in the residence washrooms because soap dispensers, paper towels and garbage cans went missing.

A quarantine at Pleasant View Care Home may be lifted by the weekend, following several residents and staff members falling ill with the Norwalk-like virus.

Care home administrator Judith Ray says staff believe the virus was brought in
by visitors.

ìWe first noticed it Dec. 29,î she related.

Staff members were getting sick, but then a few residents fell ill. Given the
symptoms were vomiting and diarrhea, it took about three days for enough people to get sick before they suspected Norwalk-like virus. It took a further four days for the Centre for Disease Control to confirm it was that particular
virus, she added.

WORRY OVER JUMP IN WINTER VOMIT BUG CASES

5 January 2006

DOCTORS are baffled by a rise in patients struck by the most common form of winter vomiting bug.

Cases of norovirus soared by 65 per cent last year in Scotland. There were 1491 confirmed cases of the bug - which causes sickness and flu-like symptoms -compared with 906 in 2004.

Scottish hospitals were hit by more than 60 outbreaks, with care homes, schools, oilrigs and ships also affected.

Doctors believe the number of confirmed cases is merely the tip of the iceberg and hundreds of thousands of people may have had it.

Norovirus: record numbers struck by violent winter bug

HELEN PUTTICK, Health Correspondent
January 04 2006

Hundreds of thousands of people have been struck down by a virulent stomach infection which has reached record levels, sweeping through hotels, hospitals, care homes and even passenger ships.

Health officials in Scotland have recorded a 65% increase in cases of the highly-infectious norovirus, the so-called winter vomiting virus, during the past 12 months.

The medical profession has been unable to explain the surge in sickness in the latest figures, although a new strain of the bug could be to blame.

The virus can strike hospital wards and force managers to turn away new patients and cancel operations until it stops spreading.

The Asahi Shimbun

An infectious and at times deadly form of gastroenteritis caused by a norovirus is on the rise, medical experts said over the weekend.

While adults usually recover from the illness in one to three days with appropriate treatment, the norovirus, commonly called stomach flu but not a strain of influenza, can prove fatal in elderly or young patients who are susceptible to dehydration or choking.

Seven elderly residents of a nursing home in Fukuyama, Hiroshima Prefecture, died last winter in a norovirus outbreak.

The Cincinnati Health Department said the food-borne virus that sickened as many as 500 people who ate at the Hilton Netherland Plaza between Nov. 29 and Dec. 3 could have been much worse if the hotel hadn't acted as quickly as it did.

Dr. Lawrence Holditch, a doctor with the health department, told the city's Education, Health and Recreation Committee on Tuesday that the hotel took several immediate steps to stop the norovirus from spreading:

Ill workers were kept away from work for the duration of their illness, plus three days because the virus can spread even after the person feels better.

Experiments Show Very Weak chlorine Solutions Can Kill Noroviruses

December 20, 2005

Chlorine solutions much weaker than previously believed can still be used to kill more than 99 percent of noroviruses, the chief cause of outbreaks of gastrointestinal illness around the world, a new University of North Carolina at Chapel Hill study concludes.

Researchers presented their findings over the weekend at the 2005 International Conference on Antimicrobial Agents and Chemotherapy, which ends today (Dec. 19) in Washington, D.C. They discovered for the first time that dilute solutions of hypochlorous acid, or free chlorine, as low as 200 -- or even 20 -- milligrams per liter will completely inactivate noroviruses on surfaces such as stainless steel and ceramic tile.

As winter edges closer, cruise ship companies that dock at the Port of Galveston are intensifying efforts to combat the seasonal spread of common flu, colds and gastrointestinal diseases.

A Royal Caribbean International ship, the Splendour of the Seas, reported an outbreak of the gastrointestinal Norovirus ó affecting about 8 percent of passengers ó when it arrived Nov. 28 in Galveston after a 14-day cruise that originated in Barcelona, Spain.

About 135 of 1,574 passengers and 12 of 724 crewmembers were affected. The ship left port later that day on a five-day cruise to Mexico and returned Dec. 1. No other unusual incidents were reported, according to a company spokesman.

GPs issue warning over tummy bug

BBC News

Doctors in Bristol and Somerset are appealing to people to help stop the spread of a virulent stomach bug in the community.

Earlier this week, four wards at Frenchay hospital stopped taking new admissions because of the Norovirus virus.

Southmead GP Will Warin warned that the bug was highly contagious and can spread very quickly.

"We're asking that people with symptoms try to ensure they don't pass it on."

He added: "For example, don't send your children to school, go to work or visit elderly relatives and make sure you wash your hands thoroughly."

People suffering the symptoms of diarrhoea and vomiting are urged to stay at home for 48 hours after the symptoms stop, as the virus can still be spread during that period.

Clean hands can prevent spread of illness

October 21, 2005

The New Milford Health Department has issued a reminder to local residents about the importance of keeping your hands clean.

The reminder comes on the heels of Clean Hands Week, which was Sept. 18-24.

Officials said that handwashing is the single most important thing one can do to prevent illness and the spread of illness.

The Center of Disease Control estimates that 5,000 people die each year from food-borne illness. It says 78 million become ill and between 79,000 and 96,000
die from hospital infections each year.

One of the direct links to many of those deaths is poor handwashing, according to the release from the local Health Department.

How Safe is the Food in Americaís Schools?

New Federal Law Gives Parents Access to Cafeteria Inspection Reports

Is your childís school cafeteria free of rodents, under-cooked or improperly stored food, and other hazards that can cause seriousóand possibly fatalófood poisoning? A new federal law makes it easier for parents to answer that question by requiring more frequent inspections and easy access to school cafeteria inspection reports.

Today the Center for Science in the Public Interest (CSPI), the nonprofit nutrition and food safety watchdog group, released its School Food Safety Bill of Rights, which tells parents how to take advantage of the new law and become involved in promoting food safety at the school level. The new law was folded into the Childhood Nutrition Reauthorization bill last year by food safety advocates in Congress, led by Senator Richard Durbin (D-IL) and Representative Rosa DeLauro (D-CT).

Norovirus: FAQ

By CDC
Sep 13, 2005

What are noroviruses?

Noroviruses are a group of viruses that cause the "stomach flu," or gastroenteritis (GAS-tro-en-ter-I-tis), in people. The term norovirus was recently approved as the official name for this group of viruses. Several other names have been used for noroviruses, including:

* Norwalk-like viruses (NLVs)
* caliciviruses (because they belong to the virus family Caliciviridae)
* small round structured viruses.

Viruses are very different from bacteria and parasites, some of which can cause illnesses similar to norvirus infection. Viruses are much smaller, are not affected by treatment with antibiotics, and cannot grow outside of a personís body.

TEMPE, Ariz. The Arizona Cardinals announced today the team has decided to move its 2005 training camp from Northern Arizona University following the recent outbreak of a virus on the school's Flagstaff campus.

The Cardinals say they're in the process of making alternate arrangements and those details will be announced when they're finalized.

Cardinals Vice President of Football Operations Rod Graves says the overwhelming concern obviously was the health and well-being of the team.

N-A-U president John Haeger says they're "deeply disappointed" by the decision.

Haeger says they understand the Cardinals' concerns and respect their decision.

Norovirus

From the CDC

Noroviruses (genus Norovirus, family Caliciviridae) are a group of related, single-stranded RNA, nonenveloped viruses that cause acute gastroenteritis in humans. Norovirus was recently approved as the official genus name for the group of viruses provisionally described as ìNorwalk-like virusesî (NLV). This group of viruses has also referred to as caliciviruses (because of their virus family name) and as small round structured viruses, or SRSVs (because of their morphologic features). Another genus of the calicivirus family that can cause gastroenteritis in humans is Sapovirus, formerly described as ìSapporo-like virusî (SLV) and sometimes referred to as classic or typical calicivirus.

Noroviruses are named after the original strain ìNorwalk virus,î which caused an outbreak of gastroenteritis in a school in Norwalk, Ohio, in 1968. Currently, there are at least four norovirus genogroups (GI, GII, GIII and GIV), which in turn are divided into at least 20 genetic clusters.

A Taste of Food Poisoning

By Carole Sugarman

My daughter never met a chicken tender she didn't like. But during a recent family vacation in Florida, 9-year-old Anna was struck with a bad case of salmonellosis -- disease caused by salmonella. And while we'll never know for sure, we strongly suspect it was caused by contaminated, undercooked poultry at one of her daily restaurant chicken meals.

There is more than a little irony in this tale of excruciating stomach pains, bathroom vigils and hospital emergency rooms.

As a food writer for 25 years, I've interviewed numerous victims of food-borne diseases and parents of children who've died from them. I've attended scores of conferences and hearings where food safety issues are debated among government officials, industry and activist groups.

What is Norwalk virus (Norovirus)?

www.about-norwalk.com

Norovirus (previously called "Norwalk-like virusî or NLV) is a member of the family Caliciviridae. The name derives from the Latin for chiliceócalyxómeaning cup-like, and refers to the indentations of the virus surface.

Nature has created an ingenious bug in Norwalk. The round blue ball actually is a protein surrounding the virus's genetic material. The virus attaches to the outside of cells lining the intestine. Then it transfers its genetic material into that cell. There it reproduces, finally killing the human cell to release new copies of it that attach to more cells of the intestine's lining.

The family of Caliciviridae consists of several distinct groups of viruses that were first named after the places where outbreaks occurred. The first such outbreak occurred in 1968 among schoolchildren in Norwalk, Ohio.1 The prototype strain was identified four years later, in 1972, and was the first virus identified that specifically caused gastroenteritis in humans. Id. At S255. Other discoveries followed, with each strain named based on the location of its discovery-location, e.g., Montgomery County, Snow Mountain, Mexico, Hawaii, Parmatta, Taunton, and Toronto viruses. A study published in 1977 found that the Toronto virus was the second most common cause of gastroenteritis in children.2

How safe are cruise vacations, ships?

By Fredrick Gary
Guest Commentary by local resident

In today's consumer world, some of the best vacation buys are undeniably cruise vacations. After all, cruise passengers are being fed, housed, transported, and entertained in grand style, and all for the price of a good hotel stay.

I have been on eight cruises and always enjoy myself to the max. Which I am pretty confident is the norm and not the exception.

In spite of the outstanding safety record of cruise lines in general, I still hear some people say that they won't go on a cruise because of their fear of ships and the sea. This attitude is surely unfounded when we consider the facts of the matter.

Health Tip: Don't Get Sick on Cruise Ships

June 24, 2005

(HealthDay News) -- Over the past couple of years, outbreaks of gastroenteritis or Norwalk-like viruses have afflicted hundreds of people, especially aboard cruise ships where confined living conditions allow the virus to spread rapidly.

Whether you're at home or traveling, you can fend off the Norwalk virus with these tips offered by the Johns Hopkins University Health After 50 medical letter:

Wash your hands frequently with soap and water, particularly before and after meals, and keep your hands away from your face and mouth.
Every so often, use alcohol-based hand sanitizers.
Don't share eating utensils or drinking glasses.
Avoid eating uncooked food.
If you're traveling, drink only bottled water.
If you're planning a trip and are over 65 or have a weakened immune system, your doctor may suggest additional precautions.

Norovirus is blamed for school illnesses

June 17, 2005

A norovirus caused the illnesses that led to hundreds of absences at the Myers Corners Elementary School in May, Dutchess County De-partment of Health officials said Thursday.

Rich Robbins, a public health sanitarian, said laboratory confirmation of the virus came Wednesday.

The Wappingers district school closed early May 13 after hundreds of children stayed home because they had fallen ill or their parents were concerned they would catch the virus during class.

Noroviruses cause "stomach flu" or gastroenteritis with symptoms including vomiting, nausea, diarrhea and some stomach cramping, according to the Centers for Disease Control and Prevention.

Sun Newspapers
6/2/2005

An apparent outbreak of a viral gastrointestinal illness among students at a Bloomington school appeared to be subsiding late last week.

That news came after more than 120 students at Poplar Bridge Elementary School became ill earlier in the week, suffering from vomiting and diarrhea, city and school officials said. None of the students required hospitalization.

Absentee rates among students at Poplar Bridge Elementary had dropped to near-normal levels by weekís end, said Dawn Willson, health service supervisor for the Bloomington School District.

Students at Porter Elementary School suffered from a commonly known ailment -- the stomach flu -- earlier this month when a large number of students were absent.

The results of samples from six students came in from the state Tuesday morning, confirming the students had had norovirus, said Micky Roberts, county health director. Norovirus is commonly referred to as stomach flu.

The Blount County Health Department was called to the school May 4 to determine what was causing the students to be sick. Roberts said when that many students are out without a reasonable explanation, then the Health Department is notified.

Summer Brings Tourists and Health Messages

Potential for Norovirus encourages agency coordination and lots of handwashing
May 23, 2005
Monday

With many cruise ships expected in Ketchikan and other Alaska communities throughout the summer, as well as thousands of other tourists arriving in Alaska by plane and automobile, the potential is high that we will see cases of Norovirus and other infectious diseases this summer according to the Alaska Department of Health & Social Services. Norovirus may be found at low levels throughout the year in some communities, however, the massive movement of people during the summer season makes it more likely to see a sudden outbreak.

The Alaska Department of Health and Social Services, Division of Public Health, is coordinating with the Centers for Disease Control and Prevention (CDC) and other local, state and federal agencies to help ensure our communities are safe and healthy.

Health officials say virus that sickened kids is likely Norwalk type
KAREN GARLOCH
Staff Writer

The illness that caused about 160 children to stay home from Matthews Elementary School Wednesday was probably a virus similar to the one that has sickened cruise ship passengers in recent years, Mecklenburg County Health Department officials said Friday.

Noroviruses, also called Norwalk-like viruses, cause "stomach flu" or gastrointestinal symptoms, such as nausea, vomiting, diarrhea and fever. The illness is usually mild and victims recover quickly, in six to 36 hours, said health director Dr. Wynn Mabry.

None of the sick children went to a hospital, but some did see doctors.

Health Experts Blame Norovirus For Sick Students

May 6, 2005

MATTHEWS, N.C. -- The Mecklenburg County Health Department said it believes the norovirus was the cause of hundreds of kids to become sick at Matthews Elementary School.

The virus causes nausea, vomiting, diarrhea and mild fever.

Health workers said it's a short-lived illness with no long-term health effects.

More than 120 students either called in or went home sick for the second day in a row on Thursday at Matthews Elementary School.

"We're seeing some students at other schools with similar types of symptoms, but not in the numbers of this particular school," said Mecklenburg County Health Department's Dr. Wynn Mabry.

Pogo Mine workers exposed to norovirus

Tuesday, May 3, 2005

Anchorage, Alaska - An outbreak of norovirus has hit the Pogo Gold Mine, located north of Fairbanks.

Of the 300 people at the camp, about half have been exposed to the virus, according to state health officials. They say it's a common virus that is spread easily in close quarters, like a cruise ship or a mining camp. Symptoms include vomiting and diarrhea, lasting one to two days.

But officials believe the worst of the outbreak is over.

Health officials say it does not pose a major health risk, and the best way to avoid it is by washing your hands.

Are Noroviruses Emerging?

Marc-Alain Widdowson,Stephan S. Monroe, and Roger I. Glass
Centers for Disease Control and Prevention, Atlanta, Georgia, USA
May 2005

In 1972, noroviruses (previously called "Norwalk-like viruses") were discovered as the first viruses definitively associated with acute gastroenteritis. During the next 2 decades, researchers were unable to develop simple methods to detect these common viruses or to find the etiologic agents of nonbacterial gastroenteritis outbreaks and hospitalizations. Indeed, of >2,500 foodborne outbreaks reported to the Centers for Disease Control and Prevention from 1993 to 1997, <1% were attributed to noroviruses, and 68% were of "unknown etiology" (1). As a result, noroviruses were out of sight and mind and thus relegated to a minor role as agents of gastroenteritis at a time when high-profile outbreaks of Salmonella Enteritidis (2) and Escherichia coli (3) had focused attention and budgets on preventing foodborne bacterial illnesses.

April 27, 2005

Cruise ships are cleaner than ever, but disease outbreaks remain historically high, according to data presented on Tuesday by the federal cruise sanitation program.

Labs approved by the U.S. Centers for Disease Control confirmed 26 outbreaks of gastrointestinal illness on cruise ships in 2004, compared with 25 the year before and 29 in 2002. By contrast there were only three outbreaks in 2001, the last year before a new variant of virus began to cause diarrhea and vomiting to increase.

"In 2001, we had this dramatic, massive increase in outbreaks associated with viruses," said Dr. Elaine Cramer, medical epidemiologist for the CDC's vessel sanitation program. The group conducted its annual meeting in Fort Lauderdale on Tuesday.

By: News 8 Austin Staff

Two customers and three employees tested positive for norovirus after being exposed to it at the Jason's Deli Arboretum location.

The virus is a gastrointestinal illness and a leading cause of foodborne diseases.

Management said there's no telling how the virus entered the deli, whether through employees or customers.

All 47 Jason's Deli employees at North Austin location were tested. Those three tested positive are not allowed to return until after they test negative for the virus.

The health department said 51 people reported getting sick after eating catered meals there on April 12 and 13.

The restaurant opened Friday after management spent 14 hours sanitizing it.

Cleaning crews disposed of all food and paper in the deli.

City restaurants clean up dirty food practices

Since 2002 Diamondback series, eateries' health violations decrease
By Matt Santoni
April 13, 2005

Two years after a rash of health code violations at several of College Parkís most popular restaurants, health department records show most businesses have cleaned up their acts.

Between 1998 and 2002, Prince Georgeís County inspection records for 29 College Park restaurants showed several downtown staples were chronic violators of county health code regulations. As of 2004, most have shown considerably fewer violations and complaints.

Dannyís Sub Shop, Ratsieís and Pizza Boliís had all been temporarily closed by the health department between 1999 and 2001 for violations ranging from improper food storage to missing permits.

Dannyís Sub Shop showed the most progress: after receiving or not correcting so many critical violations between 1998 and 2002 it was regularly classified as a ìchronic offender,î the popular late-night eatery was cited only a few times in 2004 for cleaning issues.

Tomales Bay oysters probed in mystery illness

By Jacob Resneck
April 1 2005

State health officials are investigating a mysterious illness that left 19 people sick to their stomachs after they ate raw Tomales Bay oysters. While the Hog Island Oyster Company in Marshall quickly recalled thousands of oysters sold before March 18, co-owner Terry Sawyer told The Light he doubts the illnesses were from infected oysters. In cooperation with state health officials, Sawyer on March 18 shut down the oyster farm as a precaution, although it has since been given the all clear to reopen.

"So far thereís been no connection between the illness and the oysters," Sawyer said Wednesday. "Weíre getting reports from retail places that sell our oysters that there were people who ate oysters who didnít get sick as well as people who didnít eat oysters and got sick. We sold 15,000 oysters retail and 45,000 oysters wholesale during that period. So if the oysters had been infected, youíd think weíd have a lot more than 19 cases on our hands."

New hotline handles food-safety complaints

By Judith Blake
Seattle Times staff reporter
March 23, 2005

The calls run the food-safety gamut:

ï A Seattle-area woman said she'd found walnuts in a packaged, pre-cut salad mix, though nuts were not listed in the ingredients. Her young son, who was severely allergic to walnuts, did not eat any of the nuts, but the woman worried that someone else might have an allergic reaction to the mislabeled product.

ï A man discovered mold on the meat-filled breakfast burrito he'd purchased at a convenience store.

ï A woman was dismayed to find larvae in an energy snack bar.

These are among the calls consumers have made to the new toll-free Food Safety Consumer Complaint Hotline (1-800-843-7890) launched in January by the Washington State Department of Agriculture.

Goal: to reduce the risk of food-borne illness by making it easier for consumers to lodge complaints and for officials to address them.

Norovirus common source of illness in travellers: study

Fri, 18 Mar 2005
CBC News

WASHINGTON - Travellers who come down with diarrhea after returning home from Mexico and Guatemala may be feeling the effects of Norovirus, researchers say.

It's estimated from 20 to 50 per cent of people who travel to tropical areas will experience traveller's diarrhea ñ three or more loose stool movements in 24 hours.

Noroviruses in particular are considered one of the leading non-bacterial causes of the upset.

Tips from the Journals of the American Society for Microbiology: Norovirus Prevalent in Those Suffering from Traveler's Diarrhea

Norovirus may be the most common cause of travelers' diarrhea for United States citizens returning from Mexico and Guatamala say researchers from the U.S., Guatemala, Mexico and Sweden. Their findings appear in the March 2005 issue of the Journal of Clinical Microbiology.

It is estimated that 20 to 50 percent of the people traveling to tropical areas of the world will experience traveler's diarrhea (TD). TD, defined as three or more loose stool movements in a 24-hour period, frequently results from exposure to bacterial or viral pathogens. Noroviruses (NoV's) are considered to be one of the leading causes of nonbacterial gastro-related illnesses resulting in over 23 million cases annually.

Health officials warn of increased stomach flu in RI

Mar 10, 2005

PROVIDENCE, R.I. (AP) - Health officials are warning people to wash their hands frequently and stay home if they feel sick because of an increase in reports of stomach flu.

The state Department of Health says health providers are seeing more Norovirus, which is often called stomach flu.

They say it's highly contagious. It causes nausea, vomiting, diarrhea and stomach cramps, and recovery typically takes two or three days.

It's sometimes linked to eating shellfish that has been contaminated by sewage, but is more commonly contracted by swallowing food or water contaminated with stool by an infected person.

Health officials say sick people should stay home -- especially child care and food workers.

Foodborne illness and tort- are you due diligent?

Food Safety In-Sight
Roy E. Costa, R.S., M.S.

In a perfect food safety world, operators of food facilities would place the health of the consumer above all else. Science-based foodborne illness prevention systems would be in place from farm to table and government in partnership with industry would effectively monitor the food supply so unsafe conditions could be detected and quickly corrected. In a perfect world, food safety would be a given. In reality, operators do not adopt food safety systems because of an overarching concern for public health and safety. Think about how and why the Food, Drug and Cosmetic Act of 1906 came into being. As a reminder, it came about as a result of Upton Sinclairís book, ìThe Jungleî. Sinclairís novel depicting horrendous sanitary conditions in Chicagoís slaughterhouses galvanized public opinion and forced congress to regulate the food industry. The media is still at work today exposing wrongdoing in the food industry. Since history and our modern experience prove that we cannot depend upon industry to place the good of society above business interests, we enact laws and rules to protect the health, safety and welfare of consumers.

While these laws and rules are well intentioned, they depend for the most part on public agencies for enforcement. When agencies are properly funded and have strong political support they protect the public. When they are weak or lose sight of their mission, the public faces increasing risk. Our current food safety regulatory system is a patchwork of agencies that for the most part have their roots in the earliest days of public health. While some still say the United States enjoys the safest food supply in the world (or ìone of the safestî as our government now says!) our public health infrastructure is deteriorating under the pressure of shifting legislative priorities and dwindling resources. Many health departments are cutting positions, leaving positions vacant, or trying to pass responsibility off to other agencies. While bio-security concerns have refocused the legislative agenda on public health and safety, less and less money is being spent on core public health programs. Many agencies are in serious jeopardy of defaulting on their mission. In Florida, for example, the Division of Hotels and Restaurants has come under attack in the media for failing to meet inspection quotas and failing to enforce basic sanitation and safety laws.

Norovirus Found to Cause Traveler's Diarrhea

Study of U.S. Travelers to Mexico and Guatemala Found 65 Percent Prevalence Rate

BALTIMORE, March 8 (AScribe Newswire) -- A majority of traveler's diarrhea cases among U.S. travelers to Mexico and Guatemala were attributed to Norovirus, a common cause of nonbacterial gastroenteritis outbreaks usually associated with developed countries, according to a new study by researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions. The researchers also found that the longer travelers stayed at their destination, the more likely they were to contract Norovirus infections. The study is published in the March 2005 issue of the Journal of Clinical Microbiology.

"Noroviruses are known to be a major cause of food and waterborne gastroenteritis outbreaks in domestic and unique settings, such as cruise ships, and also have been documented among military groups during deployment overseas. However, few studies have investigated the prevalence of Norovirus infection among civilians traveling from industrialized to developing countries," said Kellogg J. Schwab, PhD, corresponding author of the study and an assistant professor in the Department of Environmental Health Sciences at the Johns Hopkins Bloomberg School of Public Health.

The Dominican Republic is assuring tourists that Norovirus, the stomach flulike virus affecting much of the Caribbean and cruise ships in the area, is under control in the Dominican Republic.
According to the Commission of Health and Tourism and the Pan-American Health Organization, the first reported case of Norovirus was reported last December but no new cases have been reported since Feb. 11.
The Dominican Republic's Department of Tourism also reports there have been no new cases of malaria since Dec. 5, after an outbreak last fall.

The cruise ship industry asked the CDC to tone down their wording in reporting on-board illness outbreaks

Thursday, March 03, 2005
NewsTarget.com

The cruise ship industry wants the Center for Disease Control (CDC) to use the words "increased incidences" instead of "outbreak" when describing illnesses on board their ships. Cruise lines are required to report any instance where at least 3% of their passengers fall ill during a cruise. These illnesses are usually caused by noroviruses, which cause diarrhea and vomiting, and ships work hard to prevent the spread of these viruses.

Overview:

A group representing the cruise-ship industry has asked the federal government to change the way it reports onboard illnesses.

The International Council of Cruise Lines has asked the U.S. Centers for Disease Control and Prevention to eliminate the word "outbreak" from its health reports, and has suggested replacing it with the term "increased incidences."

Keep unwelcome norovirus stowaway from joining the cruise

Kathleen Doheny
Healthy Traveler
February 27, 2005

In January alone, five cruise-ship sailings experienced outbreaks of gastrointestinal illnesses linked to noroviruses, a group that causes acute bouts of vomiting and diarrhea. Symptoms generally subside in a day or two.

Outbreaks on ships get lots of attention, but the incidence of norovirus illnesses also is rising in other places and among the general population, says the Centers for Disease Control and Prevention, which reported recent outbreaks in nursing homes, schools and hotels.

Each year, the CDC says, about 23 million people in the United States ó 8% of the population ó contract noroviruses.

Among other ways, it can be transmitted by eating food or drinking liquids infected with the virus, touching infected surfaces or objects and then touching your face, or sharing food with an infected person.

Getting Sick on an Ocean Cruise

What Might be Hiding on Board Your Ship?
Feb. 25, 2005

Taking a cruise evokes sun, fun, fine dining, relaxation and romance -- the ingredients of a perfect vacation.

But also lurking on these ships in places you can see -- and places you cannot -- may be a cast of stowaways that could potentially ruin your holiday.

Most notable among them is the norovirus, a nasty bug that can cause a couple of days worth of severe nausea, vomiting, diarrhea, fatigue and headaches. The norovirus can spread easily when large groups of people are gathered together in close proximity, places like restaurants, schools, nursing homes, hotels -- and cruise ships.

Last month alone, there were seven norovirus outbreaks on cruise ships.

ABC News' "Primetime Live" sent teams of producers equipped with test tubes, gloves and special lights on four different cruise ships.

A New Method For Early Detection Of Disease Outbreaks

Source: Public Library Of Science
Date: 2005-02-23
http://www.sciencedaily.com/releases/2005/02/050218130731.htm

For disease outbreak detection, the public health community has historically relied on the watchful eyes of doctors, who have reported individual cases or clusters of cases of particular diseases to the authorities. But these days, the availability of electronic health-care data should facilitate more automated and earlier outbreak detection and intervention. Besides diagnoses of known diseases, other indicators--such as primary complaints of patients coming to the emergency room or calling a nurse hotline--are being collected in electronic formats and could be analyzed if suitable methods existed.

Martin Kulldorff and colleagues have developed and operated real-time disease surveillance systems based on electronic records. In an article published in the open-access medical journal PLoS Medicine, they now report a new and very flexible approach for early disease outbreak detection.

Influenza and Norwalk virus settle in for customary mid-winter visit to the Walla Walla Valley.
By Sheila Hagar of the Union-Bulletin

While local residents delayed getting vaccinated for flu - first through lack of availability, then some from a lack of initiative once flu shots arrived - influenza didn't delay its visit to the Walla Walla Valley.

And the annual favorite, Norwalk virus, is settling in for a stay, too.

Over the past several days, the Walla Walla County Health Department ``has seen a fairly large number of cases' of both, said Harvey Crowder, administrator.

Samples from local flu and norovirus victims have been sent to the state public-health lab for confirmation, he said.

``I wouldn't say it's notable or out-of-control,' Crowder said, but now is the time to follow time-honored advice - ``Mom was right, you need to wash your hands all the time.'

In the case of the norovirus, commonly referred to as the Norwalk virus, the symptoms are immediate and usually severe for about 24 hours. They include nausea, vomiting, diarrhea, and stomach cramping, sometimes accompanied by a low-grade fever, chills, muscle aches and headaches, topped with a general sense of malaise.

SANTO DOMINGO, Dominican Republic, Feb. 21 /PRNewswire/ -- The Commission of Health and Tourism together with the Pan-American Health Organization (OPS) today announced that "Norovirus," the stomach flu-like virus currently found throughout the Caribbean and cruise ships in the area, is under control in the Dominican Republic.

According to the health organizations, the first reported case of Norovirus was reported in the Dominican Republic in December of 2004. At that time three tourist destinations in the north were affected. However, since February 11 no new cases have been reported. In addition, the epidemic investigation into the presence of Norovirus at Dominican Republic hotels has found no new cases of the virus.

To protect against future outbreaks of Norovirus, the Commission of Health & Tourism and the OPS have encouraged Dominican Republic hotels to maintain their already strict sanitary controls.

Norovirus is a non-lethal gastrointestinal infection that is spread through interpersonal contact. Symptoms of Norovirus, which include vomiting and diarrhea, may last 24 to 48 hours.

Illness during Spring Break can be prevented

By Holly Bianco
February 21, 2005

Spring Break vacations are a time to relax and soak up the sun on the beach or on a cruise.

However, for those students planning to take a sea voyage over Spring Break, precautions should be taken because of a recent outbreak of viruses on cruise ships over the last three years.

The virus is called the Norovirus and it is a gastrointestinal virus usually resulting in some kind of stomach flu that is not related to influenza.

"The symptoms are primarily vomiting, diarrhea, low-grade fever, headaches and muscle aches," said Alicia Cronquist, coordinator for food-borne and enteric disease at the Colorado Department of Public Health and Environment.

Cruise group is seeking change in illness reports

February 16, 2005

FLORIDA TODAY

Recent case
Royal Caribbean's Mariner of the Seas in January: During a weeklong cruise, 276 of 3,465 passengers (7.9 percent) and 27 of 1,190 crew members (2.2 percent) were reported ill from the norovirus. The predominant symptoms were vomiting and diarrhea. -- CDC's Web site
--------------------------------------------------------------------------------------------

A group representing the cruise-ship industry has asked the federal government to change the way it reports onboard illnesses.

The International Council of Cruise Lines has asked the U.S. Centers for Disease Control and Prevention to eliminate the word "outbreak" from its health reports, and has suggested replacing it with the term "increased incidences."

The trade group also wants the CDC's Vessel Sanitation Program Web site to show how many passengers are reported sick during each day of a cruise, instead of showing cumulative totals for an entire cruise.

New disease surveillance system tested

February 14, 2005

BOSTON, MA, (UPI) -- Electronic healthcare data, such as U.S. emergency room visits or calls to a nurse, are being automated to detect the outbreak of some diseases.

Martin Kulldorff of the Harvard School of Medicine has developed and operated real-time disease surveillance systems based on electronic records.

In an article published in the medical journal PLoS Medicine, the researches report on a new and flexible approach for early disease outbreak detection.

The method, called the "space time permutation scan statistic," can detect disease outbreaks when only the number of cases is available.

The program, tested in New York City, found four highly unusual clusters of diarrhea cases, three of which heralded citywide gastrointestinal outbreaks due to rotavirus and norovirus. That, researchers said, suggests the method can detect outbreaks early, but isn't prone to false alarms.

The method has been integrated by the New York City Emergency Department. To make the method more widely accessible, it has been implemented as a feature of the freely available SaTScan software found at the Web site satscan.org.

Cruise lines don't like word 'outbreak'

The Wall Street Journal
02/14/2005

The cruise industry wants to use a new weapon to combat viral outbreaks: Calling them something else.

The International Council of Cruise Lines, a trade group that lobbies on behalf of cruise companies, has asked the Centers for Disease Control to eliminate the word "outbreak" from the agency's health reports. "If they used the words 'increased incidences,' it wouldn't be misreported by the media," says Michael Crye, the trade group's president. The CDC says it's considering the request.

The industry also wants the CDC's vessel sanitation program Web site to show how many passengers are reported sick during each day of a cruise, to better show that many passengers recover after a few days of illness. The current cumulative report tallies all passengers suffering from either three bouts of diarrhea or vomiting plus one other symptom ranging from achy muscles to fever, all within 24 hours. (The CDC tally doesn't include routine seasickness.)

While conceding that the current reporting system can make longer cruises appear riskier than shorter ones, David Forney, chief of the CDC's vessel-sanitation program, says no changes are planned to how the CDC counts illnesses. He says the agency has discussed how to reflect illness patterns on longer cruises more fairly, but the cruise industry has yet to offer an acceptable proposal.

All aboard for changes in cruising

By Elissa Leibowitz Poma
The Washington Post
February 13, 2005

Like celebrities, rundown houses and reality TV show participants, cruise lines are getting makeovers. Demand is at its highest since Sept. 11, 2001, and prices are on the rise.

Here's what's new this year:

New destinations

As the cost of the euro continues to climb, European cruises purchased in U.S. dollars are an exceptional value, cruise specialists say. Cruise lines are positioning more ships in the Mediterranean and along the coasts of northern Europe, and are selling those cruises faster than ever.

Carnival Cruise Lines will sail the Mediterranean for the first time, with eight trips scheduled from July to October. Crystal Cruises has added seven new ports of call. Radisson Seven Seas has a new series of "Top of the World" trips, focusing on northern Europe.

Meanwhile, Disney Cruise Line is doing a first: It will sail from Los Angeles to Mexico this year as part of the celebration of the 50th anniversary of Disneyland. Twelve cruises will go from Los Angeles to Mexico, then sail through the Panama Canal to the Caribbean.

Cause of outbreak at school revealed

February 10, 2005
By ERIN MAYES
Union Democrat

An outbreak last week of gastrointestinal illness at San Andreas Elementary School was caused by the highly contagious norovirus, county health officials confirmed yesterday.

The virus is transmitted primarily through consumption of food contaminated by an ill person who uses poor hygiene and by direct person-to-person contact, health officials said.

It hasn't been determined if the outbreak was spread through food, but Public Health Officer Dr. Dean Kelaita said almost everyone who had the illness at San Andreas Elementary ate at the school's cafeteria for lunch.

Norovirus is the name for a group of viruses described as "Norwalk-like viruses," so called because of a gastroenteritis outbreak in a school in Norwalk, Ohio in 1968, according to the U.S. Centers for Disease Control.

In the news

Incidents of the norovirus have increased worldwide in January, both on cruise lines and on land. Royal Caribbean's Enchantment of the Seas and Mariner of the Seas, Holland America's ms Veendam and ms Ryndam, and Princess' Sun Princess all reported incidents of the norovirus on early January cruises. Although cruise lines have rigorous procedures to sanitize public areas, passengers are encouraged to protect themselves and prevent the spread of the norovirus by washing their hands frequently with soap and warm water and minimizing contact with other cruisers should they fall ill.

Hand washing will combat shipboard 'flu'

Associated Press
Feb. 6, 2005 12:00 AM

If you're taking a cruise, make sure to wash your hands.

That advice comes from the International Council of Cruise Lines in response to concerns about outbreaks of norovirus aboard ships.

Cruise ships are susceptible to outbreaks of the highly contagious norovirus and other gastrointestinal illnesses. The Centers for Disease Control and Prevention (CDC) reported 36 outbreaks aboard ships in 2004, compared with 29 in 2003. Seven shipboard outbreaks of gastrointestinal illness have been reported for 2005.

Cruise ships are required by the CDC to have sanitary protocols to prevent and limit the spread of norovirus, but the International Council of Cruise Lines wants cruisers to know that they can protect themselves and others through simple personal hygiene.

"The most preventative measure people can take is washing their hands frequently," said Michael Crye, president of the ICCL.

If you're taking a cruise, make sure to wash your hands. That's the advice from the International Council of Cruise Lines in response to concerns about outbreaks of norovirus aboard ships.

Cruise ships - like day-care centers, hospitals and other environments where germs are easily spread - are susceptible to outbreaks of the highly contagious norovirus and other gastrointestinal illnesses.

The U.S. Centers for Disease Control reported 36 outbreaks aboard ships in 2004, compared to 29 in 2003. At least seven shipboard outbreaks of gastrointestinal illness have already been reported for 2005.

ICCL Advises On Noro Prevention

February 4, 2005
The International Council of Cruise Lines said member cruise lines are prepared for increased incidents of norovirus and encourage everyone, whether or not onboard ships, to exercise frequent hand washing as a preventative measure.

There has been an increase in norovirus incidents across the country in hospitals, day care centers, nursing homes and schools, according to Dave Forney, chief of the Vessel Sanitation Program of the U.S. Centers for Disease Control and Prevention (CDC).

With the reported increased number of norovirus cases on land, the ICCL has observed a corresponding increase in norovirus incidents on cruise ships.

23 Million Cases

The CDC estimates that 23 million people, or 8% of the population, contracts norovirus every year. Cruise ships are well under that percentage, with less than 1% of all passengers affected.

Staying Healthy On Your Cruise Vacation

February 3, 2005

When we think of going on a cruise, we picture sun-bathing on the ship's deck not getting stuck in a cabin with the stomach flu. But according to the Centers for Disease Control and Prevention, a highly contagious type of stomach bug - known as "norovirus" - is at high tide on many cruise ships.

Last weekend, about 230 people aboard the Holland America ship ìVeendamî came down with a gastrointestinal illness, forcing the trip to end early and return to Florida.

"It's not at all unusual that for any given cruise to have a handful of a dozen people to have some kind of gastrointestinal illness,î said Holland America spokesperson Rose Abello.

And although getting sick is not uncommon in such a confined space, many cruise lines are offering to waive cancellation fees and telling those who are already sick to stay home.

MUNCIE, Ind. (NLI) - Local residents who thought they had the flu might have been wrong. Delaware County health officials have reported it actually could have been the Norwalk Virus.

The Norovirus is a common intestinal illness according to Delaware County Health Officer Dr. Donna Wilkins.

Wilkins said it's often confused with the flu. However, symptoms of the Norovirus include vomiting and diarrhea, while flu symptoms more often are fever, aches and coughing.

"People acquire the Norovirus through either contaminated food or water," said Wilkins. "It is a fecal-oral transmission, so it's the person who does not use good hygiene in the restroom and then goes and prepares food, or handles food that somebody else eats."

Flu takes pleasure out of cruise

Despite the crew's best efforts, the illness hit 200 passengers and 30 crew members on a Holland-America voyage through the Caribbean.
By SAUNDRA AMRHEIN, Times Staff Writer
Published January 29, 2005

TAMPA - Before their own tummies rumbled, before they were locked in their rooms, passengers aboard the cruise ship Veendam knew things were amiss.

"You would hear people in the room next to you at night," getting sick, said Kathy Miller, 53, of Iowa.

"It was a very vocal performance," added friend Luanna Raushenberger, 55.

Both women succumbed to a pesky virus that spread to about 200 passengers and 30 crew members aboard a Holland-America cruise through the Caribbean islands. Sick passengers experienced gastrointestinal problems and were quarantined to their rooms until they were better, passengers and officials said.

Because of the virus's effects on 230 of the 1,220 passengers and 572 crew members, the Veendam returned to Tampa 13 hours early, docking at Channelside around 5 p.m. Friday instead of its planned arrival around 6 a.m. today.

Those nasty noroviruses, including Norwalk, may be getting nastier

Friday, January 28, 2005

In a matter of a few years, the term Norwalk virus has become part of the public lexicon. At this time of year, it seems like it's everywhere: grounding planes and closing daycares, spreading misery in long-term-care facilities and schools.

Infectious-disease experts say they think outbreaks are more common and there's something changing in the behaviour of the nasty noroviruses.

"We certainly believe that what we've seen over the last five years is an increase in the activity of this virus," said Dr. Paul Sockett of the Public Health Agency of Canada.

"And this is early stages yet but we have some evidence which suggests that we may have a slightly more virulent strain that's been circulating in the past couple of years," he said, adding the bug has been sowing misery "fairly well across the country."

Preventing and Controlling the Spread of Stomach Flu

Allegheny County Health Department
January 27, 2005

The Allegheny County Health Department is offering advice on how to prevent and control the spread of common viruses causing much of the intestinal illness or so-called "stomach flu" being reported this winter.

More than 90% of intestinal illnesses or stomach flu are caused by a group of viruses known as noroviruses, which are most frequently reported during the winter months.

The symptoms usually include nausea, vomiting, diarrhea and stomach cramps. While stomach flu isn't related to influenza, a respiratory illness, in some cases people with a norovirus infection also have influenza-like symptoms such as a fever, chills, headache and muscle aches.

The illness starts suddenly, but is usually brief, lasting only one or two days. It is generally not serious, however some people can feel very ill with frequent vomiting and diarrhea. They should drink plenty of fluids to prevent dehydration, especially the very young and elderly.

What is Norwalk virus (Norovirus)?

www.about-norwalk.com

The norovirus (previously called Norwalk-like virusî or NLV) is a member of the family Caliciviridae. The name derives from the Latin for chiliceócalyxómeaning cup-like, and refers to the indentations of the virus surface.

Nature has created an ingenious bug in Norwalk. The round blue ball actually is a protein surrounding the virus's genetic material. The virus attaches to the outside of cells lining the intestine. Then it transfers its genetic material into that cell. There it reproduces, finally killing the human cell to release new copies of it that attach to more cells of the intestine's lining.

The family of Caliciviridae consists of several distinct groups of viruses that were first named after the places where outbreaks occurred. The first such outbreak occurred in 1968 among schoolchildren in Norwalk, Ohio. The prototype strain was identified four years later, in 1972, and was the first virus identified that specifically caused gastroenteritis in humans. Id. At S255. Other discoveries followed, with each strain named based on the location of its discovery-location, e.g., Montgomery County, Snow Mountain, Mexico, Hawaii, Parmatta, Taunton, and Toronto viruses. A study published in 1977 found that the Toronto virus was the second most common cause of gastroenteritis in children.

Eventually this confusing nomenclature was resolved, first in favor of calling each of the strains a Norwalk-like virus, and then simply, a norovirus ñ the term used today.

Updates of Gastrointestinal Illness among passengers and crew for international cruise lines

January 24, 2005

Cruise lines are required to report all cases of GI illness aboard cruise ships to CDCís Vessel Sanitation Program (VSP). Medical staff aboard cruise ships use clinical criteria to determine self-reported (by passengers and crew) cases of GI illness; disease reports from cruise ships do not require laboratory confirmation. VSP monitors the GI reports, and provides assistance to vessels with unusual cases or elevated levels of ill passengers and crew. VSP staff conduct investigations when an unusual GI illness pattern or characteristic is found.

In contrast to cruise ships' reporting to public health authorities, land-based facilities (clinics, hospitals, doctors' offices) do not report GI illnesses.

Cruise industry always on guard

Virus blamed on 2002-03 poor performance
BY DONNA BALANCIA
FLORIDA TODAY
Jan 22, 2005

The Norwalk virus is something the cruise industry knows well.

The virus was a contributing factor to relatively poor cruise-industry performance in 2002 and 2003. It prolonged the recovery for the cruise business after the terrorist attacks of 2001.

The new outbreak on Royal Caribbean International's Port Canaveral-based Mariner of the Seas has brought back into the spotlight the threat of the virus attacking the cruise industry's booming business. And though personnel scrub and clean the ships, and people continue to take voyages, the virus still hasn't been beaten.

"We take precautions every day with a rigorous cleaning process," Disney Cruise Line spokeswoman Rena Langley said Saturday. "We have signage on our ship to tell guests to wash their hands. The focus is on every day of the year, not just during virus season."

Disney Cruise Line, like many others in the business, has felt the financial sting of the Norwalk virus. More than two years ago, it reported more than 400 passengers became sick on cruises on its ship, the Magic, which is based at Port Canaveral. The company canceled the ship's scheduled cruise for the ensuing week.

Gastroenteritis in Travelers Returning from the Dominican Republic

January 14, 2005

On January 11, 2005, the Centers for Disease Control and Prevention (CDC) was notified by the Ohio State Health Department about gastrointestinal illness in 18 of a group of 20 who had traveled from January 3-10, 2005 to the resort area of Punta Cana, Dominican Republic. The majority of ill travelers complained of diarrhea, nausea, cramps and fatigue. None required hospitalization. The Ohio State Health Department and CDC are investigating to determine the exact cause of illness. Based on the clinical presentation, norovirus disease is suspected.

Noroviruses are a group of viruses that cause the ìstomach flu,î or gastroenteritis and can be found worldwide. Recent outbreaks have been reported on cruise ships in the U.S. The symptoms usually include nausea, vomiting, diarrhea, and some stomach cramping. Although symptoms of vomiting and diarrhea can be severe, people usually get completely better after 1-3 days. It is important that people who are ill with diarrhea and vomiting drink plenty of fluids to prevent dehydration. Any traveler with persistent diarrhea and vomiting or fever should get immediate medical attention.

Frequent hand washing and attention to hygiene are important in decreasing the risk of contracting norovirus infection.

Port Everglades ñ Crew members have been preparing the "Sun Princess" to set sail from Port Everglades after a virus made dozens of crew passengers sick.

Eighty-nine passengers and five crewmembers onboard came down with a highly contagious stomach virus on the previous cruise.

The ship's medical staff quarantined one sick couple in their cabin for nearly the entire trip. Most passengers set to sail on the next cruise say they won't let the virus ruin their vacation.

"I have no worries at all. No, I'm just going to have a good time and, I'm not going to get sick. They'll make sure of that," said Alan Masters.

Still there were some passengers unhappy about the situation.

"Pissed off! That doesn't begin to tell you how I feel right now," said Ilene Rzecinski.

Crews disinfected the ship from stem to stern in preparation for the next voyage.

How can I avoid Norwalk virus?

The good news about Norwalk virus is that it does not multiply in foods as many other bacteria do. In addition, thorough cooking destroys this virus. To avoid this illness, make sure the food you eat is cooked completely. Shellfish (oysters, clams, mussels) pose the greatest risk and any particular serving may be contaminated; there is no way to detect a contaminated oyster from a safe oyster. With shellfish, only complete cooking offers reliable protection.

Wash raw vegetables thoroughly before eating or preparing salads. If you are traveling in an area that appears to have polluted water, drink only boiled drinks or carbonated bottled beverages without ice.

Immunity to calciviruses is not permanent and reinfection can occur, and infection may also spread from person-to-person. So, if you or another household member suffer a bout of gastroenteritis, then

Wash hands with soap and warm water after toilet visits, before preparing or eating food; and after caring for the sick;

Exclude persons with gastroenteritis from the kitchen; and

Always dispose of sewage in a sanitary manner.

The Environmental Health Associates have published "Norovirus Outbreak Control Guidelines" for the lodging industry, but they state that: "These guidelines should be used in conjunction with the other laws and rules governing sanitation and communicable disease control in the lodging industry and advice from medical or public health advisers. The local circumstances should always be taken into account when deciding on a plan of action."

How is Norwalk virus infection diagnosed?

Laboratory diagnosis is difficult. Diagnosis is often based on the combination of symptoms, particularly the prominence of vomiting, little fever, and the short duration of illness. Actual proof of infection requires research laboratory techniques in which Norwalk virus particles are identified by electron microscopy from samples of stool or vomitus.

Winter Bug Unleashes Its Misery

Protracted Vomiting Torments Sufferers

Friday, January 14, 2005

If you're still eating breakfast while you read this, or catching a quick bite for lunch during work, that is good fortune and bad. Looking at life positively, it means you are not suffering from the miserable sickness that is the subject of this story. A couple of paragraphs of description, though, and there's no guarantee you won't start feeling queasy.

How else to explain the sledgehammer effect of an affliction with such a grossly apt moniker as "winter vomiting disease"? This highly contagious stomach bug, which mimics many aspects of food poisoning, is a norovirus that hits hardest this time of year.

For 24 to 48 hours, it lays waste to its victims.

"I was hugging the old commode," recounted Katherine Riddle of Oakton, the first in her family to fall ill in late December.

Riddle's only warning was a few minutes of dizziness while she was teaching an afternoon flute lesson at her house. "And then, boom!" she said. She ran for the bathroom and threw up. The lesson ended quickly, but her vomiting went on and on and on. "I was doing it for the rest of the night. It was incredible."

Norovirus and Foodborne Disease, United States, 1991ñ2000

Research

Efforts to prevent foodborne illness target bacterial pathogens, yet noroviruses (NoV) are suspected to be the most common cause of gastroenteritis. New molecular assays allow for better estimation of the role of NoV in foodborne illness. We analyzed 8,271 foodborne outbreaks reported to the Centers for Disease Control and Prevention from 1991 to 2000 and additional data from 6 states. The proportion of NoV-confirmed outbreaks increased from 1% in 1991 to 12% in 2000. However, from 1998 to 2000, 76% of NoV outbreaks were reported by only 11 states. In 2000, an estimated 50% of foodborne outbreaks in 6 states were attributable to NoV. NoV outbreaks were larger than bacterial outbreaks (median persons affected: 25 versus 15), and 10% of affected persons sought medical care; 1% were hospitalized. More widespread use of molecular assays will permit better estimates of the role of NoV illness and help direct efforts to control foodborne illness.

Foodborne infections are estimated to cause 76 million illnesses, 300,000 hospitalizations, and 5,000 deaths annually in the United States (1). Several high-profile outbreaks in the last 15 years have focused attention on the role of bacteria in severe foodborne illness (2ñ4) and led to serious efforts to prevent bacterial contamination of food during all levels of processing and handlingóthe "farm-to-fork" model. However, in more than two thirds of outbreaks of foodborne illness, no pathogen is identified (5).

What are the symptoms and risks of Norwalk virus infection?

Usual symptoms of Norwalk virus infections include nausea, vomiting, diarrhea, and abdominal pain. Headache and low-grade fever may also accompany this disease. The disease is usually mild and brief. It will develop 24 to 48 hours after contaminated food or water is ingested and lasts for 24 to 60 hours. People infected with Norwalk Virus usually recover in 2 to 3 days without serious or long-term health effects.

Stomach bug packs a wallop

By Robert Miller
THE NEWS-TIMES
January 2, 2004

You can call it the Norwalk virus or the stomach flu. You can call it the flying death or the ups and outs. Or the heave ho and the pukes.
Whatever the name, it's making the rounds, leaving most people wretched and housebound for a day or two.

"We are seeing it," said Dr. William Gemmell, vice chairman of emergency medicine at Danbury Hospital. "Some years we see more of it than others. This is one of those years."

Barbara Burnsidespokeswoman for New Milford Hospital, said the emergency department there has also seen the illness on the rise ó especially in adults and seniors.

The illness is probably caused by a norovirus ó the group of viruses that circulate in the winter causing short-lived but intense bouts of vomiting and diarrhea. For most people, there's only one mode of treatment: drink lots of liquids to avoid dehydration and wait it out.

Restaurant given go-ahead to serve food again

By Jeff Wilford
The Journal Times
December 28, 2004

RACINE, WI - Health officials have all but concluded that a recent outbreak of foodborne illness was caused by a norovirus. They have also given The Chartroom, 209 Dodge St., where the outbreak apparently originated, the green light to start serving food again.

The restaurant, which was last open Dec. 21, will open again and serve food on Thursday, owner Richard Pugh said.

Diane Muri, public health administrator for the city of Racine, said The Chartroom had done everything asked of it by health officials investigating the outbreak. Pugh voluntarily closed the restaurant last week, employees washed every surface customers might touch with a light mix of bleach and water, and employees have all submitted samples to be tested by health officials.

Keeping shipshape, health-wise

THE WASHINGTON POST
December 26, 2004

My husband and I are in good health and don't qualify for a flu vaccine. Given past problems with norovirus, etc., on cruise ships, what, if anything, are cruise lines doing to address obvious concerns for flu outbreaks?

After reading the U.S. Centers for Disease Control and Prevention's information sheets on cruise ship illnesses, I felt compelled to scrub my hands - repeatedly. "Wash your hands frequently throughout the day, even if you think they don't need to be washed," the CDC advises, and for good reason.

Cruise ships, with their captive audience, can become a perfect place to transmit contagious diseases. But norovirus and flu are spread quite differently. Flu, a respiratory illness, is spread when an infected person sneezes or coughs and others breathe the same air.

December 21, 2004

The Virginia Department of Health is reporting a rise of Norovirus in Virginia. Experts say the gastrointestinal disorder, formerly called Norwalk Virus, occurs most often in the winter.

Symptoms include nausea, vomiting, diarrhea, headache and fever, which generally last from two to three days.

Doctors say the virus is very contagious. Children showing symptoms should be kept at home. Experts tell us the virus has no long term effects.

RICHMOND, Va. (AP) - The Virginia Department of Health has reported an increase in outbreaks of norovirus in Virginia.

Experts say the gastrointestinal disorder -- formerly called Norwalk virus -- occurs most often in the winter. Symptoms include nausea, vomiting, diarrhea, headache and fever, and generally last from two to three days.

An epidemiologist with the Virginia Department of Health says five outbreaks have been reported this month. Outbreaks are generally reported in places where people are in close contact such as dormitories and assisted-living facilities. Usually cases start to increase in December and drop off around March or April.

Sick of the flu? Get ready for this

Norovirus outbreaks hit in Summit County and across the country
By Tracy Wheeler
Beacon Journal medical writer
December 14, 2004

It's not the ``flu'' that everyone has been concerned about, but a virus is now making a lot of people sick.

Outbreaks of norovirus (also known as a Norwalk-like virus and commonly called the ``stomach flu'' although it has no relation to the real flu, influenza) are hitting across the country, including at a preschool in Summit County.

The illness causes nausea, vomiting, diarrhea, stomach cramping and, sometimes, a low-grade fever, chills, headache and a general sense of tiredness.

Nursing home residents recover after outbreak

December 13, 2004

(Bennington, VT - AP) ó The director of the Vermont Veterans Home in Bennington says most residents stricken during a virus outbreak last week have recovered or are recovering.

Commandant Earle Hollings Junior says the home will remain off-limits to visitors until all patients have been virus-free for 48 hours.

The norovirus usually causes stomach cramps, vomiting and diarrhea. Its most serious side effect is dehydration.

A sudden outbreak of the norovirus began in the home's dementia wing on Tuesday, spreading quickly to other wings.

Veterans home on path to virus recovery

By ZACH CHURCH
Staff Writer
Dec. 13 2004

BENNINGTON -- The Vermont Veterans Home remains on-guard against the virus that caused a virtual lockdown last week, but most of the sick have recovered or are on their way, according to Commandant Earle Hollings II, director at the home.

"It's calmed down a lot, but it's not gone yet," Hollings said on Sunday night. The home will remain off-limits to visitors until all patients have been virus-free for 48 hours.

"One person could have it in the home and we'll still be on hold," Hollings said.

The concern is that the norovirus that infected residents and staff at the home can regenerate itself - patients who recover once can get it again. Even more of an issue, Hollings said, is that it can be more dangerous the second time around, when a person's immune system is weakened from the first attack.

Virus suspected at nursing home

By John Michalak
Daily Tribune Staff Writer
Dec. 12, 2004

TROY ó An illness that swept through a Troy nursing home Thursday probably was caused by a norovirus which is the same culprit that sickened hundreds on cruise ships in recent years, medical experts said.

Paramedics from Alliance Mobile Health of Troy dressed in bio-hazard gowns transported 14 persons from the Alterra Clare Bridge nursing home, 4850 Northfield Parkway at Long Lake, to William Beaumont hospitals in Royal Oak and Troy.

All the patients are in fair condition, said Beaumont spokeswomen Ilene Wolff.

Officials are trying to determine if a person at the same nursing home who died early Thursday during a "cardiac arrest" call is connected to the illnesses. An autopsy is scheduled today by the Oakland County medical examiner.

Norovirus Outbreak Control Guidelines

Environmental Health Associates, Inc. have published "Norovirus Outbreak Control Guidelines," a valuable resource for any hospitality industry business that believes itself to be impacted by a Norovirus outbreak. The guidelines can be found at http://www.about-norwalk.com.

These guidelines should be used in conjunction with the other laws and rules governing sanitation and communicable disease control in the lodging industry and advice from medical or public health advisers. The local circumstances should always be taken into account when deciding on a plan of action.

Norwalk virus detected at Richmond Hospital; clean-up underway

November 18, 2004

RICHMOND (CKNW/AM980)-- The Vancouver Coastal Health Authority is cleaning up a non-surgical ward at the Richmond Hospital.

A Norwalk virus was detected on Friday and by Monday, 32 people including staff and patients were sick.

Hospital staff say the outbreak was contained to the cardiac, respiratory and general medicine wing where most of the patients are elderly and compromised immune systems.

Persistence of norovirus

http://www.foodsafetycentre.com.au/fsh/fshbull36b.htm

Food Safety & Hygiene, February 2001, contained an article on airborne transmission of a Norwalk like virus now known as Norovirus. In the incident described there, the function room of a large hotel was the site of an outbreak of the viral infection following a vomiting episode during a meal by one diner.
The same group of workers in the UK have now reported on a school outbreak of Norovirus which provides further evidence that aerosolisation of virus particles can lead to direct infection.

In this incident from a school enrolment of 4-11 year olds of 492, 186 pupils had some absence from school with gastrointestinal symptoms. Five members of staff were also ill. The onset of vomiting by infected children was often sudden with a number vomiting within classrooms. The areas visibly contaminated were cleaned immediately. Vomiting occurred in some but not all classrooms.

An initial environmental cleaning operation took place in the school 13 and 14 days after the first cases occurred. A quaternary ammonium compound was used for this cleaning despite advice about its potential lack of efficacy. This proved to be the case and cleaning took place again on days 19 and 20 with chlorine based products being used. The school closed from days 18 to 21 inclusive and after the second cleaning and closure,no further school absences occurred.

Rule aimed at norovirus would send sick food workers home

CIDRAP News
Robert Roos, Staff Writer
May 11, 2004

Food workers with a potentially infectious intestinal illness would be sent home under a recommendation adopted recently by a group that advises the Food and Drug Administration (FDA) on safety guidelines for the retail food industry.

The recommended provision is aimed mainly at norovirus (formerly called Norwalk virus), according to Paul Allwood, a senior environmental epidemiologist with the Minnesota Department of Health in St. Paul. Norovirus spreads easily on food and is now considered the most common cause of intestinal illness, according to the recommendation.

The current FDA Food Code says that restaurant and food service workers with intestinal symptoms generally may stay on the job but may not work with exposed food, utensils, or linens, Craig Hedberg, PhD, an associate professor of environmental and occupational health at the University of Minnesota in Minneapolis, told CIDRAP News.

The FDA Food Code is not binding but serves as a model for state and local regulations for retail food stores, restaurants, and food services. The Conference for Food Protection, a representative body of food industry officials, government regulators, academic experts, and consumers, advises the FDA on changes to the code.

Cornell expects to open Monday - Students probably sickened by Norwalk virus; source unknown

Beaver County Times & Allegheny Times
Bill Vidonic, Times Staff
March 21, 2004

CORAOPOLIS - Classes are expected to resume Monday in Cornell School District after nearly 60 students fell ill last week with the same virus that has sickened hundreds of passengers on cruise liners.

Allegheny County Health Department spokesman Guillermo Cole said Saturday that tests this week should confirm the presence of the Norwalk virus. He said the exact source of the outbreak might never be known, though it's probably not from food.

Cole said the virus is easily spread from person to person, mostly by someone who fails to wash his hands thoroughly. A person can spread the germs simply by touching something, he explained.

Pupils in the elementary school began suffering from vomiting, diarrhea and low-grade fever Thursday night, Cole said, and 40 children stayed home Friday.

By late Friday morning, nearly 20 additional students and one teacher at the school were ill, and all 800 students at the Cornell campus were dismissed early.

The illness was concentrated among the 400 pupils in kindergarten to grade 6, school officials said.

Officials Find What's Ailing Oscar

March 13, 2002

And the Oscar goes to...Outbreak.

Los Angeles County health officials have figured out the source of those freak illnesses that hit the Academy of Motion Picture Arts and Sciences' Scientific and Technical Awards last Saturday. And it ain't pretty.

For outstanding technical achievement in making nearly one-third of the 550 guests at the Regent Beverly Wilshire Hotel sick, the Health Department singled out the Norwalk virus, a class of infectious agents that spread like wildfire through guests' meals and typically causes gastroenteritis, according to the Hollywood Reporter. Symptoms include "a short incubation period and a fairly short-lived illness" characterized by vomiting, diarrhea, nausea and low-grade fever.

Public health director Jonathan Fielding told the Reporter the Norwalk virus usually spreads through food contaminated with feces or vomit. Health officials examined the posh ballroom where the low-key black-tie affair was held, as well as the Beverly Wilshire's food preparation and service areas to rule out any health-code violations.

Mystery illness sickens guests at second wedding

BY DAN LAVOIE
February 25, 2004

A virus that sickened guests at a Valentine's Day wedding in Orland Park also made guests at a second wedding sick.

Cook County health investigators at first thought the illness was limited to about 30 people who attended an afternoon wedding Feb. 14 at the Orland Chateau, 14500 La Grange Rd.

Now, they say that at least 19 guests -- and maybe dozens more -- who attended a wedding there that evening also were hit by a virus that caused severe diarrhea, vomiting and a low-grade fever.

Health investigators suspect the Norwalk virus, which also has sickened hundreds of cruise-ship passengers in recent months. The Norwalk virus typically is spread through food that's improperly handled by an infected person, though it also can be spread person-to-person, according to the federal Centers for Disease Control and Prevention.

But confirmation of the cause of the outbreak will take at least a couple of weeks, county health department spokeswoman Kitty Loewy said.

August 28, 2003

Just four days into the new school year about 110 Gateway Elementary students and 15 staff members came down with a stomach bug that kept them home Thursday.

State health officials are investigating the cafeteria and the water system at the Travelers Rest school in hope of identifying what caused about 18 percent of the 625 students to become ill. The normal absentee rate is about 3 percent, said Susan Clarke, spokeswoman for Greenville County Schools.

Severe vomiting and diarrhea began to hit students and staff Wednesday night, said Mike Gaillard, food program supervisor for the Greenville County Health Department.

"It started in the middle of the night ó he was throwing up and had a little fever," said parent Cindy Howard, of her youngest son who is in kindergarten.
"I didn't think about it being related to school until...I took my other son to school," she said, "and realized it was something going on for a lot a lot of families."

Norwalk Virus

How to protect yourself
Health Daily News 2003

Over the past couple of years, outbreaks of gastroenteritis or Norwalk-like viruses have afflicted hundreds of people, especially aboard cruise ships where confined living conditions allow the virus to spread rapidly.

Whether you're at home or traveling, you can fend off the Norwalk virus with these tips offered by the Johns Hopkins University Health After 50 medical letter:

ïWash your hands frequently with soap and water, particularly before and after meals, and keep your hands away from your face and mouth.
ïEvery so often, use alcohol-based hand sanitizers.
ïDon't share eating utensils or drinking glasses.
ïAvoid eating uncooked food.
ïIf you're traveling, drink only bottled water.
ïIf you're planning a trip and are over 65 or have a weakened immune system, your doctor may suggest additional precautions.

Norwalk Virus: Outbreaks on Land, Sea

Despite cruise ship woes, problems more prevalent on land
By Gary Gately
HealthScoutNews Reporter
January 7, 2003

Major outbreaks of Norwalk-like virus that have infected 700 people in Boston provide the latest evidence that the nasty stomach bug that sickened so many cruise ship passengers is hardly limited to the high seas.

In fact, experts say, the gastrointestinal illness is much more prevalent on land.
The 17 Boston outbreaks struck nursing homes, rehabilitation centers, homeless shelters and hospitals during the past six weeks. Local health authorities call the outbreaks the worst in almost two decades since the viruses were identified. Symptoms include diarrhea, vomiting, stomach pain and headaches for up to two days.

Experts say the outbreaks reflect an upsurge in the number of cases of Norwalk-like viruses, which are named after an outbreak in Norwalk, Ohio, in 1968.
Federal health officials blame the same viruses, the leading cause of gastrointestinal illness, for nine outbreaks aboard cruise ships within the past six months.

The cruise ship stomach bugs gave new meaning to "seasick," creating memories vacationers would just as soon forget, and drew international headlines that suddenly made Norwalk-like viruses a familiar term.

But the cruise ship viruses represent but a tiny fraction of at least 23 million Norwalk-like illnesses in the United States each year, federal health officials say. They add that the number could be much greater because many cases likely go unreported.

Norwalk Virus: At sea and at home

By Ruth SoRelle, MPH
January 2003

In 1968, more than half the students and teachers at an elementary school in Norwalk, Ohio, developed a stomach illness that involved nausea and vomiting. When they went home, 32 percent of the people who lived with them also became ill. This disease called ìwinter vomitingî occurred frequently across the United States.
The cause of their distress was not identified until 1972, when Albert Z. Kapikian, MD, now with the National Institute of Allergy and Infectious Diseases, discovered a 27-nanometer virus-like particle in an infectious stool filtrate from that Norwalk, Ohio, outbreak. The virus was named Norwalk, making the Ohio town of 16,000 famous worldwide.
The federal Centers for Disease Control and Prevention estimate that as many as 23 million people in the United States become ill from the virus or its cousins each year. Most recently, the virus has hit the cruise ship industry hard, with large numbers of people reported as ill on more than four ships sailing out of Florida ports within a month.
Little information was available about Norwalk virus and less could be done until 1990 when its genome was cloned in the laboratory of Mary Estes, PhD, a professor in the department of molecular virology and microbiology at Baylor College of Medicine.
ìThat opened up a molecular era,î said Estes. ìIt made a big difference.î

Coroner confirms virus that killed golfer, 15

Virus caused death of teen
Carol Sowers
The Arizona Republic
December 2002

SOUTH PHOENIX - The Maricopa County Medical Examiner's Office has confirmed that a 15-year-old golfer died after contracting the Norwalk virus that sickened 82 other golfers during a tournament at the Thunderbirds Golf Course.
Dr. Kevin Horn said in his report that even though the flulike virus was not found in earlier tissue testing of Nils Beeman, the autopsy points "convincingly toward a diagnosis of acute Norwalk gastroenteritis as the underlying cause of death."

The Ahwatukee Foothills teen, who choked to death on his own vomit, was found dead in his parents' bathroom on July 19 after participating for several days in a golf tournament at Thunderbirds.

Officials believe the virus was spread through contaminated water and ice in the golf course's coolers. The teen's death triggered widespread changes in the way golf courses handle water.

Outbreaks of Gastroenteritis Associated with Noroviruses on Cruise Ships

United States, 2002

During January 1--December 2, 2002, CDC's Vessel Sanitation Program (VSP), which conducts surveillance for acute gastroenteritis (AGE) on cruise ships with foreign itineraries sailing into U.S. ports (1), received reports of 21 outbreaks of AGE* on 17 cruise ships. Of the 21 outbreaks, nine were confirmed by laboratory analysis of stool specimens from affected persons to be associated with noroviruses, three were attributable to bacterial agents, and nine were of unknown etiology. Seven outbreaks were reported in 2001, and of these, four were confirmed to be associated with norovirus (CDC, unpublished data, 2002). This report describes five of the norovirus outbreaks that occurred during July 1--December 2, 2002, on cruise ships.

Ick! I'm sick from my cruise: Norwalk virus is all around us

By Gina Kim
Seattle Times staff reporter
December 11, 2002

If you're a breathing human being, chances are you've eaten it.
The intestinal ailment dubbed the Norwalk virus is so common that 23 million Americans ó one in 10 ó suffer from its symptoms each year.

The cruise-ship industry has been hit hard recently by the illness, which has afflicted thousands of passengers in the past six months. Seattle-based Holland America canceled two cruises ó one on the Ryndam and another on the Amsterdam ó so crews armed with steam cleaners and chlorine solutions could scour every inch of the luxury liners after passengers got sick on back-to-back cruises. Disney Cruise Line canceled a cruise aboard the Magic. Other cruise lines have experienced large-scale outbreaks.

But experts say people are susceptible to the virus simply by stepping outside of their homes. "These are extremely common outbreaks," said Marc-Alain Widdowson, an epidemiologist with the Centers for Disease Control and Prevention's Respiratory and Enteric Viruses branch. "It's probably the leading cause of diarrhea in the U.S., so when people are assessing their risks of going on a cruise, ... they should know that going to that restaurant down the road is just as risky."

Norwalk-Like Virus Tied to Cruise Outbreaks

Disney boat suffers apparent relapse after port cleaning
By Adam Marcus
HealthScoutNews Reporter
November 27, 2002

Health officials today blamed a Norwalk-like virus for last week's illnesses aboard a Disney cruise ship that is again at sea, this time with 104 sick passengers and counting.

The Disney Magic liner had been cleaned in port after 275 people fell ill with nausea and vomiting on a week-long voyage that ended Saturday. The ship set sail again from Port Canaveral, Fla., Saturday night, only to become a floating hospital again. In addition to the 104 ill passengers now on board, 19 crew members also have developed gastrointestinal problems during the current week-long Caribbean cruise, officials said.

David Forney, a cruise sanitation specialist at the Centers for Disease Control and Prevention, said Norwalk-like virus had also turned up in stool samples of passengers on Holland America's Amsterdam, which had more than 500 cases of gastrointestinal illness this month on its most recent cruise. That boat is now sitting in Port Everglades, Fla., for cleaning.

Norwalk-like viruses cause an estimated 181,000 cases a year of gastrointestinal illness. The group, named for a school outbreak in Norwalk, Ohio, is one of the most frequent sources of food poisoning.

Cruises urged to sanitize

VIRUSES: Recent illnesses aboard ships spark call to boost cleaning measures.
By Paula Dobbyn
Anchorage Daily News

State and federal epidemiologists are urging cruise-ship companies to aggressively sanitize and disinfect their vessels to prevent Norwalk-like viruses from spreading among passengers.

After a series of viral outbreaks sickened hundreds of cruise passengers this summer, the Alaska Department of Environmental Conservation, the Alaska Division of Public Health and the federal Centers for Disease Control and Prevention have issued new guidelines. The voluntary measures announced Thursday call for unusually strong chlorine cleansers, easy access to motion sickness bags, super-hot laundry temperatures, and meticulous hand washing, among other steps.

Norwalk-like viruses are typically spread through fecal matter or vomit, the epidemiologists said.

In June, more than 250 people aboard the Ocean Princess came down with flu-like symptoms, including nausea, vomiting and diarrhea. The bug was identified as a Norwalk-like virus, a hardy strain that can withstand freezing temperatures and temperatures up to 145 degrees Fahrenheit, said Sue Anne Jenkerson, nurse epidemiologist with the state public health division. "It's very hard to eliminate," said Jenkerson.

Cruise ships seasick

BY INA PAIVA CORDLE
icordle@herald.com

The serious stomach virus that afflicted 438 passengers on board the Holland America Amsterdam is becoming more prevalent on cruise ships and can be dangerous for the elderly or those with health problems, said an expert with the Centers for Disease Control.

''We're finding since last May that we've had many cruise ships that have had problems with the Norwalk virus, not only in the United States but throughout the world,'' said David Forney, chief of the vessel sanitation program at the CDC.

Even though it takes 24 to 36 hours to incubate, two new cases were reported aboard the Amsterdam by Tuesday afternoon, said Holland America spokeswoman Rose Abello. One passenger became ill early Monday evening, which she said indicates the person was already exposed before boarding.
''Every precaution is being taken onboard, and our efforts are really about communicating to guests how to minimize and prevent the spread of the virus,'' Abello said.

For Holland America, the outbreak on the Amsterdam marked the second time in four months that hundreds of passengers contracted the same illness on one of the cruise line's ships. The Ryndam, which sailed to Alaska in July, had 395 reported cases before the vessel was pulled from service, disinfected and returned to sea.

Norwalk-Like Virus--Associated Gastroenteritis in a Large, High-Density Encampment

July 2001

Virginia--Norwalk-like viruses (NLVs) are an important cause of gastro-enteritis in the United States, with approximately 23 million cases of NLV-associated gastroenteritis occurring each year (1). NLVs accounted for 96% of nonbacterial gastro-enteritis outbreaks reported to CDC during January 1996--June 1997 (2). These outbreaks are common especially in settings of crowding and poor sanitation (2,3). Transmission of NLVs in these settings is facilitated by high attack rates (82%) (4), a low infectious dose (<100 virions), the absence of long-lasting immunity, the durability of the organism (5), and the potential for multiple modes of transmission (3,6).

In 2001, outbreaks were reported from youth camps in Wisconsin and Florida, resulting in closure of the camps (7; CDC, unpublished data, 2001). This report describes an outbreak of NLV-associated gastroenteritis at a large youth encampment in Virginia and the successful use of control measures to limit spread of illness to other campers. Rapid, effective containment is a central goal of public health response when outbreaks of infectious diseases occur.

"Norwalk-Like Viruses"

Public Health Consequences and Outbreak Management

Summary
"Norwalk-like viruses" (NLVs) cause outbreaks of gastroenteritis and are spread frequently through contaminated food or water. Molecular diagnostics now enables detecting viruses in clinical and environmental specimens, linking of NLV strains causing outbreaks in multiple geographic locations, and tracing them to their sources in contaminated food or water. This report reviews recent advances in NLV detection and provides guidelines and recommendations for investigating NLV-related outbreaks, including specimen collection and disease prevention and control. This report also updates information provided in CDC's previously published, Viral Agents of Gastroenteritis: Public Health Importance and Outbreak Management (MMWR 1990;39 [No. RR-5]:1--24). These CDC recommendations are intended for public health professionals who investigate outbreaks of acute gastroenteritis but could be useful in academic and research settings as well.

The Norovirus Infection

What is a norovirus?
Noroviruses are a group of related viruses that cause acute gastroenteritis, sometimes called the stomach flu, in humans.
In more technical terms, noroviruses are single-stranded RNA, nonenveloped viruses. Their genetic information is encoded in a single strand of RNA and they lack an envelope.

Why are they called noroviruses?
Noroviruses are named after the original strain "Norwalk virus" which caused an outbreak of gastroenteritis in a school in Norwalk, Ohio, in 1968. Norovirus was recently approved as the official genus name for this group of viruses.
Several other names have been used in the past for noroviruses, including:
ïNorwalk-like viruses (NLV);
ïCaliciviruses (because they belong to the virus family Caliciviridae);
ïSmall round structured viruses (because of their morphologic features).
The caliciviruses are so named because of their "Star of David" shape with cup-shaped (chalice) indentations.

What symptoms are caused by norovirus infection?
Norovirus infection usually starts suddenly. The infected person often feels very sick with nausea and vomiting and watery non-bloody diarrhea with stomach cramps. Vomiting is more common in children than adults. Sometimes there is a low-grade fever. There may also be chills, headache, muscle aches, and a general sense of tiredness.
Studies with volunteers have shown that as many as 30% of norovirus infections may be asymptomatic. These people are infected with the virus but have no symptoms (asymptomatic). The role of asymptomatic infection in the transmission of norovirus is not well understood. It is possible that people who seem well can transmit the virus.

WARREN - Restaurant operators in Ohio are, according to this story, hoping education and clean bills of health will stop customers from focusing on recent news stories about outbreaks of food-borne illnesses and persuade them to eat out. So far, local restaurateurs and the Ohio Restaurant Association say the scares aren't affecting their business.

Deloris Bennison, ORA director of communications, was quoted as saying, "People are eating out as much as ever. If they are not going out to eat, it's an economical factor."

The story says that among recent outbreaks were multiple cases of Norwalk virus originating at a Warren wedding reception catered by G's Golden Gate that resulted in the restaurant temporarily losing its food service license; fatal cases of hepatitis A at a Chi Chi's restaurant near Pittsburgh reported by Pennsylvania health officials; and at least 57 cases of salmonellosis reported by the U.S. Food and Drug Administration as being associated with food purchased at Sheetz deli counters in three states in early July.
