  Norovirus is the most common cause of acute gastroenteritis in the United States. Each year, it causes about 21 million illnesses and contributes to about 70,000 hospitalizations and 800 deaths. Norovirus is also the most common cause of foodborne-disease outbreaks in the United States.
• FoodSafety.gov: Norovirus (Norwalk Virus)

  Norovirus infection can cause severe diarrhea and vomiting and is a major cause of gastrointestinal illness in closed and crowded environments, such as hospitals, nursing homes and cruise ships, because it is highly infectious.
