Overview
- The Centers for Disease Control and Prevention reported on July 9 that 843 domestically acquired cyclosporiasis cases have been confirmed across 31 states and that more than 1,500 additional potential U.S. cases are under review.
- Michigan has reported an unusually large local surge with about 1,562 cases, a total far higher than the CDC tally because state reports include probable cases and tests still under federal review.
- Federal and state teams including the CDC and FDA are conducting patient interviews, specialized stool testing and supply‑chain tracebacks focused on fresh produce but have not linked illnesses to any single product, grower or supplier.
- Cyclospora causes prolonged watery and sometimes 'explosive' diarrhea, diagnosis needs specific repeated stool tests, treatment is the 10‑day antibiotic trimethoprim‑sulfamethoxazole, and roughly 86 people have been hospitalized with no confirmed deaths.
- Health officials advise thorough hand washing, careful washing or cooking of produce, cleaning food‑prep surfaces, and that case counts will likely rise because of diagnostic limits and common multiweek reporting delays.
