Kansas health officials are reporting 55 cyclosporiasis cases so far in 2026, with a sharp increase in domestically acquired infections since late June. The Kansas Department of Health and Environment (KDHE) says 37 of the cases have been classified as domestically acquired, 17 likely followed international travel, and one case remains under investigation to determine where the infection was acquired. Western Kansas News reports the state is working with local health departments to interview cases and identify any shared exposure that could help prevent additional illness.
KDHE notes that outbreaks of cyclosporiasis have been occurring nationally in 2026, and the current Kansas cases have not been connected to outbreaks in other states. For context, Kansas reported 23 cases through July 15 in 2025. The agency also points out that yearly case totals can vary widely.
Cyclosporiasis is caused by Cyclospora cayetanensis and is spread through food or water contaminated with feces; it is not known to spread from person to person. Symptoms typically appear two to 14 days after exposure and can include sudden gastrointestinal illness. People who develop sudden gastrointestinal symptoms are encouraged to contact a healthcare provider, and KDHE also emphasizes prevention steps such as cooking produce when appropriate and considering extra caution—especially for people at higher risk of dehydration or weakened immune systems.
Healthcare providers must report suspected cases to KDHE or local health departments within 24 hours or the next business day, and the state updates case counts every Wednesday on its infectious disease dashboard.
