A member asked:

Does everyone get the severe vomiting from norovirus? is it possible to just get diarrhea with it? or vomit only once?

A doctor has provided 1 answer

Everyone's different: Norovirus causes explosive epidemics of diarrhea, usually mild, and with a spectrum of symptoms ; signs--nausea in 88%, abdominal cramps in 67%, vomiting in 66%, muscle aches in 56%. Generally, the illness lasts no more than 1-2 days, but can produce dehydration in the elderly (who may require hospitalization).
