A cyclosporiasis outbreak is affecting multiple states, with Iowa seeing a notable rise in cases. The Iowa Health and Human Services Department is actively investigating these cases, which may be linked to the national outbreak.12
As of Thursday, Iowa has reported 184 cases of cyclosporiasis in 2026, a sharp increase from 61 cases at the same time last year. Interviews have been conducted for 117 cases, revealing that 45 individuals reported international travel, according to HHS.34
State health officials are in communication with the CDC regarding these cases, which are reported once interviews are completed. HHS emphasizes that Iowans must exhibit consistent symptoms and have either a positive laboratory result or an epidemiological link to a confirmed case to be classified as part of the outbreak.56
The situation highlights the importance of monitoring and reporting in controlling the spread of cyclosporiasis, a parasitic infection that can cause severe gastrointestinal illness. As investigations continue, health officials urge the public to remain vigilant and report any symptoms consistent with the infection.
“Iowa has reported 184 cyclosporiasis cases so far in 2026, up from 61 by the same point in 2025, with 45 of 117 interviewed cases involving international travel. State health officials say consistent symptoms and a positive lab result or epidemiological link are required for a case to be reported to the CDC.”
