WHO Says Hantavirus Outbreak on Cruise Ship Is Not a Pandemic Like COVID-19
WHO says a hantavirus outbreak aboard cruise ship MV Hondiusis with three deaths poses low pandemic risk, as the virus requires extensive close contact for human-to-human transmission unlike COVID-19.
The World Health Organization (WHO) has clarified that the hantavirus outbreak aboard the cruise ship MV Hondiusis does not represent a pandemic threat comparable to COVID-19, even with three fatalities recorded. Five confirmed cases have emerged from eight suspected patients, and health authorities are actively tracing dozens of passengers and crew members who left the vessel previously.
WHO epidemiologist Maria van Kerkhove stated that hantavirus transmission differs fundamentally from COVID-19 and seasonal influenza, requiring extensive close contact for human-to-human infection. This cruise ship incident represents the first clearly documented case of human-to-human transmission. The WHO has assessed the overall public health risk as low.
The MV Hondiusis, operated by Netherlands-based Oceanwide Expeditions, departed from Ushuaia, Argentina on April 1st with approximately 150 passengers and crew from 28 countries. Some passengers disembarked at Saint Helena, a British Overseas Territory in the South Atlantic, on April 24th.
Multiple countries including the United Kingdom, United States, and Singapore have begun monitoring and tracking passengers returning from the vessel. Of the three deaths, one was a 69-year-old Dutch woman confirmed to have hantavirus infection, along with her husband, and a German woman who died aboard ship pending cause investigation. The Dutch government revealed the infected woman traveled to South Africa after leaving the ship before her death. Some passengers have been asked to monitor themselves closely for symptoms.
WHO cautioned that the disease's incubation period may extend up to six weeks, meaning additional cases could still emerge. Argentine authorities are preparing to survey rodents in the Ushuaia area, believed to harbor hantavirus-carrying rat species.
Symptoms initially resemble common flu—chills, muscle pain, weakness, headache, nausea, and vomiting. In severe cases (uncommon), symptoms include hemorrhagic fever with kidney failure, or severe respiratory disease with potential pulmonary edema, which can be fatal rapidly.
