According to the U.S. Centers for Disease Control and Prevention (CDC), there have been 4,173 laboratory-confirmed domestic cases of cyclosporiasis identified since May 1, but the federal agency is “aware of more than 7,400 additional cases that are not yet laboratory confirmed and require further investigation and analysis.” This brings the grand total of cases to 11,537. However, the CDC notes that it does not include “probable” cases in its data, meaning the number could be higher which explains discrepancies between state data and the CDC’s tracking.
From May 1 – July 20, 2026, 41 states have reported cases of the parasite-induced illness, and there have been 308 hospitalizations. Michigan stands as the state reporting the most cases. Ohio appears to stand as a top state reporting the parasite as well.
The CDC emphasizes that “true number of people sick with cyclosporiasis was likely higher than the number reported” as many individuals recover on their own and do not get formally tested to confirm the illness.
