Norovirus is a highly contagious virus and the leading cause of diarrhea and vomiting (commonly called the "stomach flu") in the United States. Anyone can get infected with this virus and get sick. Some people who are infected with the virus do not have any symptoms at all. For most people who get ill, the symptoms are minor, lasting only a few days.
