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.
Because the symptoms of norovirus are similar to those of other common viral diarrheas like rotavirus, it is necessary to do specific tests to identify the virus. Norovirus cannot be cultured in a laboratory.
