OSHA Noroviruses Fact Sheet


Noroviruses (NoVs) were named after Norwalk, Ohio, where a NoV strain (subsequently called the Norwalk strain) caused the first sudden major diarrhea and vomiting outbreak (referred to as acute gastroenteritis or AGE) in 1968. In addition to causing disease in humans, some NoV strains have caused disease in cows, pigs and mice. There have been no documented cases of animal NoVs being transmissible to humans or vice versa.
