Kansas health officials monitoring three people exposed to Andes hantavirus

The Kansas Department of Health and Environment is monitoring three Kansas residents who had high-risk exposure to a person with confirmed Andes hantavirus after international contact with an individual from the MV Hondius cruise ship, where an outbreak occurred. The three individuals are not currently symptomatic and were not on the cruise ship themselves. As of May 13, 2026, there are no suspected or confirmed cases in Kansas, and health officials assess public risk as extremely low. The Andes virus spreads person-to-person through prolonged close contact with symptomatic individuals and can cause fatal hantavirus pulmonary syndrome, with symptoms appearing 4-42 days after exposure and no specific treatment available.
