Viral Gastroenteritis
Viral gastroenteritis is an infection
caused by a variety of viruses that
results in vomiting or diarrhea. The
affected person may also have headache,
fever, and abdominal cramps ("stomach
ache"). Symptoms may begin as early as 12 hours
following exposure or as late as 48
hours after exposure, and typically last
24 to 60 hours.
The viruses
that cause gastroenteritis, such as
Norovirus, are easily transmitted
through food, by person-to-person
contact, or by contaminated surfaces.
In most cases
ill persons recover without medical
attention. Norovirus infection
occasionally results in hospitalization
due mainly to dehydration, with the very
young and elderly at greater risk. Those
with severe diarrhea should drink lots
of liquids.
Frequent hand washing using soap and
warm running water for a minimum of 20
seconds and preventing contamination of
food, drinks, water, and ice are
critical to prevent the spread of
viruses that cause gastroenteritis.
Refer to the links below for more
information about viral gastroenteritis
as well as a fact sheet and cleaning
guidelines for norovirus, a common virus
that cause gastroenteritis.

County Health Department can arrange for
testing of samples from ill persons to
