Noroviruses are a group of viruses that cause the “stomach flu”
Much to our belief, when we think we have the flu, and within one or two days, it seams to
subside, it’s really not influenza. The “stomach flu” is NOT related to the flu (or influenza), which is
a respiratory illness caused by a different virus. It really is a “norovirus” recently approved as the
official name for this group of viruses; previously it had been referred to as “Norwalk virus” or
“Norwalk-like virus.”
Symptoms of illness caused by noroviruses?
The symptoms of norovirus illness 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. Symptoms usually begin 24-48 hours after exposure to the virus, but can appear as
early as 12 hours.
Is the norovirus disease serious?
Norovirus disease is usually not serious, although people may feel very sick and vomit many times
a day. Most people get better within one or two days, and they have no long-term health effects
related to their illness. Sometimes people are unable to drink enough liquids to replace the liquids
they lost because of vomiting and diarrhea. These persons can become dehydrated and may need
special medical attention. There is no evidence to suggest
that an infected person can become a long-term carrier of
norovirus.
How people become inf ected with noroviruses.
2. 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 (for
example, caring for someone with the illness, sharing foods or eating utensils with someone
who is ill).
Noroviruses are very contagious and can spread easily from person to person. Persons working in
day-care centers or nursing homes should pay special attention to children (especially those in
diapers) or residents who have diarrheal illness which may be caused by norovirus. This virus can
spread rapidly throughout such environments.
Dishwashing Won’t Kill Tummy-Troubling virus
I have a customer from my Graphic
3. Design company that sells commercial
Vapor Cleaning Machines to hospitals
for their kitchens. We posted the
following document to his website
regarding the norovirus, and its
difference to the common stomach flu
(influenza).
Commercial dishwashers can kill everyday bacteria, but not norovirus.
The norovirus is the cause of stomach flu and many foodborne illnesses around the world,
according to a new study. Although restaurant-industry guidelines for cleaning dishes and
silverware eliminate bacteria, they are not effective against norovirus, said researchers from Ohio
State University. They found the
virus can withstand both manual and mechanical washing.
“We know that when public food establishments follow the cleaning protocols, they do a very
good job at getting rid of bacteria,” study leader Melvin Pascall, associate professor in the
department of food science and technology, said in a university news release. “Now we can see
that the protocols are less effective at removing and killing viruses, and this may help explain why
there are still so many illnesses caused by cross-contaminated food.”
For the study, published recently in the journal PLoS One, researchers contaminated cream cheese
and reduced-fat milk with a norovirus, E. coli or Listeria, three common causes of foodborne illness.
These dairy products were then applied to stainless-steel utensils, ceramic plates and drinking
glasses. The utensils were washed by hand or in a dishwasher following sanitizing protocols that
used chlorine and quaternary ammonium compound (germicidal detergent).
Both hand-washing and dishwashers reduced E. coli and Listeria to safe levels. Although
dishwashers were more effective at eliminating potentially harmful bacteria and viruses, the
researchers found neither cleaning method could reduce the presence of norovirus.
“Even though the protocols were able to kill some of the virus, norovirus is highly contagious and it
takes only a few viral particles to infect humans,” noted Jianrong Li, assistant professor of food
virology. “These results would indicate that neither the detergents nor sanitizers used in current
cleaning protocols are effective against the norovirus at the currently used concentrations.”
“Proper sanitation and handling remain the single biggest factor that can prevent
crosscontamination of food and dishware at food-service establishments,” Pascall said. “However,
it appears that we need to identify better agents or methods to significantly reduce the presence
of norovirus and work to update the protocols.”
The researchers noted that norovirus is responsible for 90 percent of nonbacterial cases of
gastroenteritis outbreaks.
Norovirus, which can easily contaminate food or water, spreads rapidly through confined
populations, such as cruise ships, dormitories and prisons. According to the U.S. Centers for
Disease Control and Prevention, norovirus each year causes an estimated 91,000 emergency
room visits and 23,000 hospitalizations for severe diarrhea among children younger than 5 years.
So this misconception that whenever we think we have the one or two day f lu,
is really a norovirus, nothing related to the stomach f lu.
