Reported cases of cyclosporiasis, an intestinal illness caused by a parasite, are nearing 1,000 in Michigan, local health officials said Wednesday.

Since June 22, at least 992 cases have been confirmed, a spokesperson from the Michigan Department of Health and Human Services (MDHHS) told ABC News. At least 36 people have been hospitalized.

Typically, the state sees about 50 cases per year, meaning cases are nearly 20 times higher than on average.
