Health officials say the Norwalk virus caused dozens of people at Sparrow's Dimondale nursing home to experience nausea, vomiting and severe diarrhea.
Health officials say an outside source probably brought the virus into the nursing home. Investigators say the virus was not related to mass food or water contamination, and they say it spread quickly because the nursing home residents were living in such close quarters.
Experts say the virus only lasts a couple days, and it's not life threatening. They do say people can prevent themselves from getting sick by thoroughly washing their hands.
