Overview
- Federal data show the CDC had confirmed 843 domestically acquired cyclosporiasis cases and reported 86 hospitalizations, and the agency said on July 9 it was reviewing more than 1,500 additional potential domestic cases.
- State health departments report substantially higher totals with Michigan reporting about 1,562 cases concentrated in southeast counties and many hospitalizations that exceed the CDC’s confirmed count.
- Investigators from the CDC, FDA and state health agencies are conducting patient interviews, specialized stool testing, genomic comparisons and supply‑chain tracebacks but have not linked illnesses to any single product, farm or supplier.
- Diagnosis requires specific stool tests that often need multiple samples and public health labs are strained, which has caused reporting lags that make national totals trail state counts and will likely raise confirmed numbers as results arrive.
- Health officials urge thorough handwashing, careful washing or cooking of fresh produce, prompt medical testing for persistent watery diarrhea, and treatment with trimethoprim‑sulfamethoxazole when infection is confirmed.
