What happened
Michigan has reported more than 700 cyclosporiasis cases since June 22, including 36 hospitalizations as of July 6, after listing 170 cases on June 30. Illinois has reported 141 cases, and federal health officials say several states are seeing higher-than-expected infections during the usual summer season. Cyclosporiasis is caused by the Cyclospora parasite, is commonly linked to contaminated fresh produce, and can cause prolonged watery diarrhea, cramps, bloating and nausea. Health officials have not identified a source for the current outbreak, and heavy testing demand is straining some laboratories.
