A recent hantavirus outbreak on the MV Hondius cruise ship has raised public health concerns as passengers return to the United States. Fox News senior medical analyst Dr. Marc Siegel discussed the outbreak, noting that human-to-human transmission, though rare, is possible. The return of passengers from locations such as Tenerife and Praia has underscored the importance of containment measures.
Canadian health officials confirmed that one of four Canadians returning from the cruise ship, involved in an international Andes hantavirus outbreak, tested positive. In total, three deaths were linked to this outbreak. The Public Health Agency of Canada, after initially describing the case as ‘presumptive positive,’ confirmed the test result. Further testing will be conducted at a national laboratory to clarify details.
The World Health Organization reported 11 cases associated with the cruise outbreak, consisting of eight confirmed cases, two probable cases, and one inconclusive case. Among these were three fatalities. The Associated Press noted that the confirmation by Canada brings the positive cases from the ship to ten. Despite this, only one of the four returning Canadians tested positive.
The Andes virus, linked to the MV Hondius outbreak, is the sole hantavirus strain known to be capable of spreading between people, typically through prolonged close contact. Officials confirmed that a traveler in their 70s returned positive, while their companion tested negative. A third person from Vancouver Island and a British Columbia resident in their 50s remain in isolation.
No confirmed cases in the United States have been linked to the cruise. Nonetheless, a U.S.-repatriated passenger had inconclusive results and is undergoing further testing. Meanwhile, Ontario County, New York, health officials announced an investigation into a suspected locally acquired hantavirus case unrelated to the cruise.
The outbreak started after the MV Hondius, with 147 passengers and crew, set sail from Argentina on April 1 for a South Atlantic journey. This situation has prompted global precautions, including in the Netherlands, where Radboud University Medical Center quarantined staff after mishandling specimens from a hantavirus patient.
Comparisons between this outbreak and the coronavirus pandemic have arisen. However, Dr. Siegel emphasized that hantavirus is much harder to spread. Unlike the coronavirus, transmitted through airborne droplets, hantavirus requires specific conditions for transmission. Siegel highlighted that hantavirus cases in the U.S. have been reported for decades, yet remain infrequent.
Although the World Health Organization noted that person-to-person transmission might have occurred on the cruise, they assessed the risk to the global population as low. The Andes virus remains the only hantavirus with documented human-to-human transmission, but such spread is rare.
