Cyclosporiasis Cases Surge in Michigan

As of July 13, Michigan has confirmed 2,640 cases of cyclosporiasis, a foodborne illness characterized by severe diarrhea and dehydration. The outbreak has led to 44 hospitalizations across the state. Cases have been reported in 43 of Michigan's 83 counties, with Monroe County experiencing the highest number.

The infection, caused by the microscopic parasite Cyclospora cayetanensis, is typically contracted through the consumption of contaminated food or water. While most foodborne illnesses resolve quickly, cyclosporiasis symptoms can persist for weeks. Health officials are urging entities that prepare or serve raw produce to implement preventative measures.

The rise in cases began sharply in early July, with daily infections peaking at 239 on July 8. Most infections are occurring in individuals aged 30 to 59 years old, affecting a broad range of age groups. The Michigan Department of Health and Human Services is monitoring the situation closely.
