Headlines
What is Norovirus?
o Group of related single stranded RNA (Ribonucleic Acid), non enveloped viruses that cause acute gastroenteritis.
o Formerly called Norwalk-like Virus
o Highly contagious
o Cause of 50% of all foodborne outbreaks of gastroenteritis
o Able to survive freezing and
high temperatures
TAXONOMY INFORMATION
Noroviruses are a genetically diverse group of
single-stranded ribonucleic acid
Non-enveloped virus, who belongs to the
Caliciviridae family
Norovirus can be divided into five distinct
genogroups: GI ,GII ,GIII ,GIV ,GV
The GI and GII and GIV Noroviruses infect
humans and
GIII Norovirus infects pigs and cows.

Interesting Facts
Was discovered and named after a gastrointestinal illness outbreak in Norwalk, Ohio, in 1968
Norovirus virions can live in the environment for up to four weeks
often called a stomach bug -- in the United States, according to the CDC
Norovirus is called by other names including stomach flu, food poisoning and “cruise ship flu”
The virus can live in an infected person's stool for two weeks or more

Norovirus causes about 21 million illnesses, 70,000
hospitalizations, and 800 deaths each year, according to
the Centers for Disease Control and Prevention (CDC)

SYMPTOMS
• Symptoms usually start within
24 to 48 hours after exposure
• Inflammation in stomach
and intestines
• Stomach pain
• Nausea
• Diarrhea
• Fever
• Headache
• Body ache http://www.cdc.gov/norovirus/preventing-infection.html
o Fecal-oral route
o Indirect contact with the virus on contaminated
surfaces.
o Via contaminated food and water
o Shellfish from sewage contaminated water
Transmission
Foods That Cause
Norovirus• Common foods that cause
outbreak
• Leafy greens (such as
lettuce),Fresh fruits, and
Shellfish (such as oysters).
• Raw Foods
• Restaurants are associated with
norovirus outbreaks twice as often
as cruise ships
Treatment options
There are no antiviral drugs for treatment of NorVoinfections
No vaccines are currently available
Illnesses usually last 24 to 72 hours
Dehydration is most common application
Sports drinks can help with mild dehydration, but water is best
You can also buy oral rehydration fluids over the counter at most drug and grocery stores
Getting too dehydrated is dangerous
In extreme cases, may have to be hospitalized to maintain and regain body fluids.

Wash your hands frequently.
Disinfect household surfaces
Promptly
With Clorox bleach
Wash soiled clothing.
Avoid contaminated food or water.
Cook shellfish completely to kill the virus.
Avoid going to work or school if diarrhea appears.
