Overview
- Federal data show 843 confirmed domestically acquired cases and 86 hospitalizations as of July 9, and the CDC says it is aware of more than 1,500 additional reports under review.
- Michigan has reported 1,562 cases since late June, a jump that far exceeds typical annual counts and has driven much of the national attention.
- CDC, FDA and state teams are conducting patient interviews, specialized stool testing, genetic comparisons and supply‑chain tracebacks but have not linked illnesses to a single food, grower or supplier.
- Cyclospora cayetanensis causes prolonged watery and often 'explosive' diarrhea, requires specific stool testing for diagnosis, and is treated with the antibiotic combination trimethoprim‑sulfamethoxazole.
- Laboratory backlogs and reporting lags are delaying national case confirmation, officials expect counts to rise, and they advise handwashing, thorough produce washing or cooking, and prompt medical testing for prolonged diarrhea.
