INDIANAPOLIS — A norovirus may have caused hundreds of people to become sick last week after eating at an Olive Garden restaurant, a health official said Monday.  Stool samples from three restaurant employees and one patron tested positive for a norovirus, which can cause nausea, vomiting and diarrhea, he said.  Outbreaks of noroviruses have taken place in restaurants, cruise ships and other places where people eat food handled by others, according to the U.S. Centers for Disease Control and Prevention.  The Health Department was still working to pinpoint the exact source of the illnesses, Althardt said.
