Three Passengers Dead After Suspected Hantavirus Outbreak on Cruise Ship

A suspected hantavirus outbreak aboard the MV Hondius, a cruise vessel traveling between Argentina and Cape Verde, has resulted in three deaths and at least three additional cases as of early May 2026. The WHO has confirmed at least one case, with epidemiological and genomic sequencing investigations ongoing.

Hantavirus — typically transmitted through contact with infected rodent excreta — causes two severe syndromes: hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome. The WHO noted limited person-to-person transmission is possible. No specific treatment exists, though early medical intervention may improve survival outcomes. Medical evacuation coordination is underway across multiple national health authorities. Read the full article from The Guardian here.
