Michigan confronts a rapidly growing cyclosporiasis outbreak across 21 counties

Michigan’s health department reports a large, growing cyclosporiasis outbreak with more than 225 cases across 21 counties and Detroit as of July 1; the source is under investigation and may involve imported fresh produce, though a single multistate link has not been established by the CDC. Symptoms include watery diarrhea, cramps, and bloating, and treatment is antibiotics. Public health officials urge doctors to test stool samples and report positives, while the public should practice proper hand hygiene and thoroughly wash produce (avoiding prewashed items, using a produce brush, and refrigerating cut or cooked produce). Authorities note cyclosporiasis is not known to spread person-to-person, and Ohio is conducting its own related investigations while monitoring for possible connections.
