How to prevent infection, diarrhea

Key Points:

• Over 170 Michiganders have contracted cyclosporiasis, a parasitic gastrointestinal illness causing explosive diarrhea, with cases reported in multiple counties including Monroe, Wayne, and Washtenaw.
• The Michigan Department of Health and Human Services is collaborating with local health departments and the state agriculture department to investigate the outbreak, which began around June 22, but the specific source remains unidentified.
• Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, commonly found in tropical and subtropical regions, and outbreaks in the U.S. have been linked to imported fresh produce such as basil, cilantro, and lettuce.
• Health officials advise thorough handwashing and careful handling of fresh fruits and vegetables, including washing produce under running water and refrigerating cut items promptly, to reduce the risk of infection.
• The illness can be treated with antibiotics, but untreated cases may last for days to months with possible relapses; individuals experiencing symptoms are urged to seek medical care and stay hydrated.
