It's not the flu, but it's causing widespread illness across the country, and is difficult to treat. Norovirus is not a reportable disease in Illinois, so there is not an accurate count as to how widespread it may be. Anecdotal evidence, however, indicates no difference that in previous years in Madison County.
But that's not an invitation to let your guard down, says Amy Yeager, Public Information Officer with the Madison County Health Department. She says careful hand washing can help prevent the spread of norovirus.
The Centers for Disease Control and Prevention is reporting outbreaks of the stomach illness jumped 30-percent last month. Symptoms include dehydration, diarrhea and projectile vomiting. CDC officials say there's really no treatment for norovirus. The illness spreads easily in places where people are in close contact such as schools, hospitals and cruise ships.
