It’s spreading around the globe and now hitting the United States.
In the U.S., it is now accounting for about 60 percent of norovirus outbreaks, according to report released Thursday by the Centers for Disease Control and Prevention.
Norovirus – once known as Norwalk virus – is highly contagious and often spreads in places like schools, cruise ships and nursing homes, especially during the winter. Last month, 220 people on the Queen Mary II were stricken during a Caribbean cruise.
Sometimes mistakenly called stomach flu, the virus causes bouts of vomiting and diarrhea for a few days.
