Canadian health authorities have confirmed a hantavirus infection linked to the international outbreak aboard the MV Hondius cruise ship, as global health agencies continue monitoring a cluster that has resulted in three deaths. The Public Health Agency of Canada said one of four Canadians who returned from the vessel tested positive for the virus after an earlier presumptive diagnosis by British Columbia officials.
The agency said additional laboratory testing would be conducted, though officials did not specify whether the process was intended for further confirmation or strain analysis. The infected individual had traveled with a companion, identified as a Yukon couple in their 70s, who later tested negative. Health authorities also said another passenger from Vancouver Island remains in isolation, along with a British Columbia resident in their 50s.
The outbreak tied to the Dutch expedition cruise ship has drawn increasing international attention as health officials work to contain potential spread. According to the World Health Organization, 11 cases linked to the voyage had been identified as of May 13, including eight confirmed infections, two probable cases, and one inconclusive result. Subsequent reporting indicated the Canadian confirmation raised the number of positive cases connected to the ship to 10. No confirmed U.S. cases tied directly to the cruise outbreak have been reported, although one repatriated American passenger was undergoing retesting after inconclusive results.
The MV Hondius departed Argentina on April 1 for a South Atlantic voyage carrying 147 passengers and crew members. The outbreak has prompted quarantine measures and heightened precautions in several countries, including the Netherlands and Australia. Dutch medical authorities quarantined staff members at Radboud University Medical Center after concerns that biological samples from a hantavirus patient may not have been handled under the strictest safety protocols. Australian officials also transferred passengers arriving from the vessel into quarantine facilities near Perth.
Health experts have emphasized that hantavirus transmission remains significantly less contagious than respiratory viruses such as COVID-19. The World Health Organization has assessed the overall global risk as low, although it noted that Andes virus — the only hantavirus strain known to spread between humans — may have been transmitted person-to-person aboard the ship. Medical experts have said such transmission remains rare and difficult, with hantavirus generally not spreading through airborne respiratory droplets in the same way as coronavirus infections.
