Brunswick Schools said Tuesday thatits high school would be joining the elementary and middle schools in closingbecause of a norovirus outbreak.
Senior Health Correspondent Monica Robins tells us what it is and how you can avoid it.
Norovirus is an icky little bugthat makes life miserable.
It only takes 10 particlesto cause 24 to 48 hours of vomiting and diarrhea misery.
But there's a simple way to prevent it -- soap and water.
Routine handwashingcan help break the cycle.
Handwashing is great against bacteria, viruses even the spore-forming bacteria that is resistant to alcohol.
The virus can remain active for seven days, even on surfaces and it is extremely contagious.
