A parasitic infection that causes weeks of watery diarrhea has infected nearly 1,000 people in Michigan. The size of the outbreak makes it the largest in Michigan history and one of the nation's largest in years.
The source of the cyclospora infections hasn't been determined, but investigations into similar illnesses are underway in 28 other states, including Ohio, where people living right across the border from Michigan are showing signs of the illness, the Associated Press reported.
Michigan officials first reported the outbreak last week when there were more than 170 confirmed cases in the southeast part of the state since June 22. Typically, the state sees approximately 50 cases per year. On Wednesday, the number of cases had exploded to 992, with 40 cases requiring hospitalization.
The illness, called cyclosporiasis, is not usually life-threatening. It's usually treated with antibiotics.
