2010 County Fair Ends With Serious Illness for Some Participants. Indiana
The investigation indicated that an outbreak of lower gastrointestinal intestinal (GI) illness occurred among persons that had some association with the county fair. The likely source of infection for the initial cases was exposure to animal feces. It was not possible to identify which animal or animals were the source of infection because more than one animal barn was visited by those initially infected. It is possible that mild secondary cases occurred in one family. Lab test results were not confirmatory in identifying a relationship between cases.
