Since the end of December, Maine CDC has investigated 16 reports of gastroenteritis outbreaks statewide. Norovirus Genotype II has been identified as the cause of one of the outbreaks. Norovirus infections typically increase during the winter months, and Maine CDC routinely receives reports of suspected and confirmed norovirus outbreaks each year. Public health partners are encouraged to consider norovirus when assessing clusters of gastroenteritis and to act promptly to prevent the spread of illness.
Noroviruses spread easily, causing more than 20 million gastroenteritis cases each year in the U.S. 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.
