Prevent the Spread of Norovirus
Norovirus spreads easily, causing 19-21 million cases of gastroenteritis (inflammation of the stomach or intestines or both) each year in the United States. There's no vaccine to prevent norovirus infection and no drug to treat it. Wash your hands often and follow simple tips to stay virus-free.

Surveillance of Norovirus Outbreaks
Noroviruses are the leading cause of reported outbreaks of gastroenteritis in the United States. Outbreaks can happen to people of all ages and in a variety of settings. CDC collects data on norovirus and helps to investigate norovirus outbreaks. This provides important information about how the virus spreads and therefore, the best ways to prevent it.
