1 American returning from hantavirus-stricken cruise showing symptoms, another U.S. passenger positive – HHS | 10 May 2026 | An American passenger returning to the U.S. from the hantavirus-stricken MV Hondius cruise ship has tested positive for the deadly virus, while a second is showing mild symptoms, health officials said. The two passengers will fly inside biocontainment units during a repatriation flight to bring all 17 U.S. passengers from the luxury cruise liner to the National Quarantine Unit at the University of Nebraska Medical Center, the Department of Health and Human Services announced on Sunday evening. One of the passengers has tested “mildly PCR positive” for Andes virus — which already claimed the lives of three passengers aboard the ship and sickened several others. The other passenger is currently exhibiting mild symptoms.
