Andes hantavirus confirmed in Yukon passenger from MV Hondius

The Public Health Agency of Canada announced on Sunday that laboratory testing validated a presumptive positive result for the Andes strain in a passenger who had been on the MV Hondius. According to the agency, the indiidual was part of a couple from the Yukon who fell ill while at sea and were later transferred to Vancouver Island for isolation.

Four Canadian travelers isolated; three remain hospitalized

British Columbia’s provincial health officer reported that four Canadians were flown to Vancouver Island after exposure on the cruise ship. Of those, three are currently receiving hospital care, while the fourth , who showed only mild symptoms, continues isolation at home. Officials note that older age can increase the risk of severe hantavirus outcomes.

World Health Organization alerted as precautionary measure

Canada’s health agency took a precautionary step by informing the World Health Organization of the confirmed case, underscoring the rarity of Andes hantavirus outside South America. As the first such case reported worldwide in a Canadian, authorities emphasized strict handling protocols during the patients’ transfer and arrival.

Who remains at risk? Monitoring low‑risk contacts

Public health officials have asked the remaining low‑risk group—individuals who were on the ship but did not develop symptoms—to monitor their health closely. While no further cases have been identified, the agency continues to track these contacts, reflecting a cautious approach to prevent any secondary transmission.

What still needs verification? Source of the virus on MV Hondius

Key unanswered questions include how the Andes strain entered the cruise environment, as the virus is typically endemic to South America. The source of contamination aboard the MV Hondius has not been confirmed, and investigators have yet to determine whether other passengers or crew might have been asymptomatic carriers.
