April 25, 2008 - Good Hygiene Helps Prevent Norovirus Spread

Hayden, ID -- After several recent outbreaks of Norovirus, a virus that can cause Gastroenteritis or what is sometimes called the “stomach flu,” the Panhandle Health District (PHD) is reminding people to protect themselves and others by washing their hands frequently and disinfecting household surfaces.

“We know Norovirus is present in the community and it’s unpleasant to have,” says Randi Lustig, program manager of PHD’s epidemiology department. “We want the public aware that it can have particularly detrimental effects on the elderly and infants.”

Since February, five senior living care centers have reported group illnesses in which Norovirus has been confirmed or suspected. More than 275 people at those centers have reported symptoms that include nausea, vomiting, diarrhea and, sometimes, stomach cramping, low-grade fever, chills, headaches, muscle aches and fatigue.

The group illnesses suggest the virus also has infected individuals in the community. People don’t typically seek medical help for the short-term symptoms, making it impossible to tally accurately the number of those infected.

Norovirus symptoms usually begin 12 hours to two days after exposure to the virus and last a day or two. There is no specific medical treatment. Drinking plenty of fluids is recommended to prevent dehydration, particularly in seniors, infants and people with weakened immune systems.

Norovirus is highly contagious and spreads easily from person to person. The virus is present in the stool and vomit. It’s passed to others who come into contact with infected stool or vomit through poor hygiene practices or proximity to a vomiting person. People also catch the virus from close contact with an infected person or by sharing eating utensils or foods with someone who is ill.

PHD advises people with Norovirus symptoms to stay home and wash their hands often, particularly after toilet visits or changing diapers and before touching food. Disinfect household surfaces with a solution that’s one part bleach to 10 parts water. Immediately wash clothes or linens that could be contaminated with the virus. Flush vomit or stool immediately and disinfect the surrounding area.
