The cruise ship MV Hondius, at the center of a hantavirus outbreak, arrived in Rotterdam, Netherlands, on Monday, 18 May 2026, after a troubled journey that began in Argentina in April. The vessel carried approximately 150 people from 23 countries at the start of its voyage, but only 25 to 27 individuals—primarily crew members and two medical staff—remained on board by the time it docked. Three deaths have been confirmed due to the outbreak: a Dutch couple and a German citizen .
Upon arrival, the remaining crew and medical personnel were placed under quarantine measures, with some isolating at port facilities and others self-isolating at home. The ship will undergo disinfection as part of containment efforts . Spain previously allowed the vessel to anchor off the Canary Islands to facilitate the evacuation of passengers and crew .
The World Health Organization (WHO) has assessed the global risk as low, stating that the hantavirus strain involved does not transmit from human to human. The outbreak has, however, prompted international monitoring and raised discussions about public health responses to maritime disease outbreaks . Separately, a confirmed case of hantavirus in Arad, Romania, involved a 25-year-old man infected with a rodent-borne strain, reinforcing that human-to-human transmission is not a concern in this context .
