Michigan faces a large, growing Cyclospora outbreak across several counties

State health officials say more than 170 cyclosporiasis cases have been identified across at least seven Michigan counties (Monroe 70; Lenawee 33; Washtenaw 21; Wayne 12; Shiawassee 7; Jackson 7; Livingston 7), with 24 more cases in 11 other counties including Detroit, prompting an investigation into a likely contaminated produce source. The illness is food- or waterborne, not spread person-to-person; people with sudden, persistent diarrhea should seek medical care, and residents should follow food-safety practices such as washing hands and washing produce.
