Cyclosporiasis outbreak surges to over 4.1K confirmed cases

A cyclosporiasis outbreak has surged to over 4,173 confirmed cases across 41 U.S. states this week, with symptoms including severe diarrhea and hospitalizations rising to 308. The CDC suspects multiple sources, initially linking cases to shredded iceberg lettuce from Mexico, but later retracted this connection after false positives. State health departments are struggling to trace cases due to the parasite's complexity, relying on manual investigations.
