Take steps tp prevent norovirus this season

As the influenza season begins, state health officials want to remind Hoosiers this is the Norovirus season as well. Viral gastroenteritis, caused by Norovirus, is now widespread throughout the state.

Indiana has had 28 suspected and 11 confirmed outbreaks since November, in long-term care facilities, hospitals, and restaurants.
"Norovirus is highly contagious and affects the gastrointestinal system of humans," said State Health Commissioner Judy Monroe, M.D. "Most people think they have food poisoning when they actually have Norovirus."

Although commonly called "stomach flu," Norovirus infection should not be confused with influenza, which is a respiratory illness accompanied by fever, sore throat, cough, and muscle aches.

Symptoms of Norovirus include vomiting, diarrhea, cramps and nausea, and can appear anywhere from 12 - 72 hours after exposure. Symptoms usually last 24 - 48 hours, although people may still be able to infect others up to two weeks after their symptoms end.

People usually become infected by eating or drinking items that are contaminated, touching contaminated surfaces or objects and then touching their mouth, or having direct contact with another person who is infected. The virus can survive outside of the body for a long period of time on surfaces such as hands, countertops, door knobs, and dishes.

Health officials say Norovirus should not be confused with other bacterial infections, including E. coli and Salmonella.

E. coli and Salmonella usually produce fever, and E. coli O157:H7 can cause kidney failure in some people.
Norovirus only lasts for 24 - 48 hours, while E. coli and salmonella symptoms can last as long as a week.
The source of Norovirus is infected people, but the other two can enter the food chain even before the food is harvested or processed.
"The best way to avoid spreading Norovirus is to wash hands thoroughly after using the bathroom, changing diapers, and before fixing or eating food," said Dr. Monroe. "People can prevent spreading the virus by limiting contact while they're sick with symptoms of vomiting or diarrhea."

There is no treatment for Norovirus, although most people get better in one or two days and suffer no long-term health effects. It is important that people avoid dehydration by drinking plenty of fluids.

"There are multiple strains of this virus and our immunity wanes quickly, so a person can get the same virus year after year and still become ill," said Dr. Monroe.

Other steps to prevent the spread of these illnesses:

"¢ Clean and disinfect contaminated surfaces, such as bathroom fixtures and toys, with a bleach-based cleaner or other disinfectant.
"¢ Immediately remove and wash clothing and linens with soap and hot water after being soiled.
"¢ Avoid preparing food or caring for others if you have diarrhea or vomiting.
