Overview
- Federal data updated July 9–10 shows about 843 confirmed domestically acquired cyclosporiasis cases while the CDC says it is reviewing more than 1,500 additional possible domestic cases that require further analysis.
- Michigan has reported 1,562 cases concentrated in southeast counties and dozens of states are investigating suspected infections, with at least 86 hospitalizations reported nationally and no deaths confirmed.
- State and federal teams, including the CDC and FDA, are conducting patient interviews, supply‑chain tracebacks and genetic testing but have not linked the illnesses to a single food, grower or supplier.
- Cyclospora cayetanensis is a parasite spread by ingesting food or water contaminated with human feces; diagnosis needs targeted stool testing and the standard treatment is a 10‑day course of trimethoprim‑sulfamethoxazole.
- Public health advice urges washing hands and produce, cooking when possible, prompt testing and treatment for prolonged diarrhea, and warns that routine sanitizers and washing may not fully remove the parasite so case counts and investigations are likely to expand.
