The Norovirus can be spread very easily. In a place like a long term care facility, it's even easier. You have a lot of people living in a relatively confined space.

That's why staff take extra precautions like washing off walkers to prevent its spread.

So far this season, Dane County has seen more than its fair share of Norovirus outbreaks. Since November there have been five -- that number jumps to 12 when you add the outbreaks that have taken place at long term care facilities.

In Columbia County, they had three outbreaks over the course of just a few days last month.

Susan Lorenz , Columbia County's Health Officers says, " I have never experienced three Norovirus outbreaks with in a time period of nine days."

Between January 16 and 25 two long term care facilities and one school saw outbreaks. Normally, there are about 10-to-12 kids who miss class at Poynette Elementary due to illness. On the 20th of last month between 80 and 90 kids were out sick or about one-fifth the schools total population.

" If you are ill with nausea, diarrhea or other symptoms. Please stay home. Don't go to work. Don't send your child to school until you are symptom free for at least some say 24-hours for Norovirus. It's 48-hours, " says Lorenz.

If you do get sick with the Norovirus make sure to wipe down all the surfaces in your home. The virus can survive for up to 12 days.

The best defense is good hygiene. Make sure to wash your hands frequently. If soap and water aren't available then use hand sanitizer.
