Overview
- The CDC’s surveillance report through June 16 documents 145 domestically acquired cyclosporiasis cases across 17 states with about 20 hospitalizations and an additional 45 travel-associated infections.
- Michigan reported a fast-growing cluster of more than 170 cases concentrated in seven counties over roughly nine days in late June that is not yet reflected in the CDC tally.
- CDC, FDA and state and local health departments are conducting patient interviews, lab testing and traceback work focused on fresh produce because past outbreaks have repeatedly been linked to contaminated fruits, herbs and salad mixes.
- Health officials say reported counts likely understate the true number of infections because many people recover without testing and they urge clinicians to test persistent watery diarrhea and treat confirmed cases with trimethoprim-sulfamethoxazole (TMP-SMX).
- Public guidance stresses thorough produce washing, avoiding cross-contamination and prompt care for ongoing diarrhea, and investigators warn the probe could find multiple separate clusters rather than a single nationwide source.
