    According to new work by researchers from the Netherlands, New Zealand and the U.S. Centers for Disease Control and Prevention （CDC）， about 14 percent of all norovirus outbreaks are attributed to contaminated food.

    Noroviruses are one of the leading causes of gastroenteritis worldwide. In the U.S., the virus causes 19-21 million illnesses, 56,000-71,000 hospitalizations and 570-800 deaths.

    The most common symptoms of a norovirus infection are diarrhea, vomiting, nausea and stomach pain. Other symptoms can include fever, headache and body aches. Anyone can be infected with norovirus and get sick, but illnesses can be especially serious for young children and older adults.
