Summary
Iowa has logged 184 cyclosporiasis cases so far in 2026, up from 61 at the same point in 2025, with state officials saying some may be tied to a broader U.S. outbreak.
117 case interviews have been completed, and Iowa Health and Human Services is using those findings to report cases to the CDC as it follows up on possible links.
45 interviewed patients reported international travel, a factor investigators are weighing as they sort travel-related infections from outbreak-connected cases.
Iowa counts a case only when symptoms are consistent and patients have either a positive lab result or an epidemiological link to a confirmed infection.
The parasitic illness can cause explosive diarrhea, and officials say the national outbreak already involves thousands of cases across nine states.
