A deadly hantavirus outbreak on the cruise ship MV Hondius has led to multiple infections and the repatriation of passengers to more than 20 countries [6].
This incident is significant because the Andes strain of hantavirus can be transmitted from person to person [7]. Unlike many other hantaviruses, this capability prompts health authorities to implement aggressive monitoring and evacuations to prevent wider community spread.
Health officials said that more than 140 people on board were potentially exposed to the virus [1]. Among those connected to the outbreak are 10 Canadians [1]. While two passengers initially tested positive [3], three additional passengers from Spain, France, and the U.S. later tested positive [4].
Beyond the confirmed cases, authorities fear that 62 other individuals may have been exposed [5]. This has triggered a complex international medical response as passengers are flown back to their home countries for observation.
The ship was sailing in the Atlantic near the Canary Islands during the event [2]. However, investigators in Argentina are currently working to determine the exact origins of the outbreak [2].
"Some passengers have returned to the US," a report from The Guardian said [8].
The response includes the coordinated effort of health ministries across multiple continents to track the movements of the passengers, and crew to ensure that no new clusters of the virus emerge in urban centers.
“The Andes strain of hantavirus can be transmitted from person to person”
The person-to-person transmissibility of the Andes strain transforms a localized zoonotic event into a potential international public health risk. Because the MV Hondius carried passengers from more than 20 countries, the repatriation process requires stringent quarantine and monitoring protocols to prevent the virus from establishing a foothold in regions where the strain is not endemic.
