Not all people who are infected with a norovirus will develop symptoms. If symptoms of a norovirus infection do occur, the illness tends to begin suddenly. Common norovirus symptoms include: 1  Nausea. 2  Vomiting. 3  Watery diarrhea. 4  Some stomach cramping. 5  Dehydration.
Normally, if you have recurring infections, symptoms are less severe each time. Norovirus infection outbreaks are more likely to occur in crowded or closed communities, such as cruise ships, long-term care facilities, prisons, overnight camps, and dormitories - places where the virus can spread rapidly from human-to-human.
