American evacuated from cruise ship tests positive for hantavirus, another has symptoms, HHS confirms

One of the 17 American citizens evacuated from the MV Hondius cruise ship and flown back to the U.S. tested positive for hantavirus without symptoms, according to the U.S. Department of Health and Human Services, and another person had mild symptoms.

Those two Americans traveled in the plane's biocontainment united "out of an abundance of caution," HHS noted in a Sunday night post on X.

A motorcade of emergency vehicles drove the 17 Americans to ASPR Regional Emerging Special Pathogen Treatment Center (RESPTC) facilities at the University of Nebraska Medical Center/Nebraska Medicine in Omaha.

"Each individual will undergo clinical assessment and receive appropriate care and support based on their condition," the post added.
