Cruise Ship Hantavirus Crisis: Three Patients Flown to Europe from Stranded Vessel

Praia, Cape Verde — Three patients suspected of carrying hantavirus were airlifted Wednesday from a luxury cruise ship anchored off this West African archipelago. The MV Hondius, operated by Oceanwide Expeditions, reported the outbreak after departing Argentina more than a month ago on a remote Atlantic voyage.[1][2] Three passengers had already died from the illness, prompting urgent evacuations and isolation measures for those remaining on board.

Timeline of the Deadly Outbreak

The MV Hondius left Ushuaia, Argentina, on April 1, bound for an expedition-style cruise through Antarctica and remote South Atlantic islands such as South Georgia, Nightingale Island, Tristan da Cunha, St. Helena, and Ascension.[1] The first suspected case emerged early in the journey, with a Dutch man dying on board around April 11. His wife was later evacuated to South Africa, where she succumbed to the virus, and tests confirmed hantavirus posthumously.[3]

Additional deaths followed, including a German passenger, bringing the toll to three. Health officials recorded eight suspected cases in total, with three confirmed through laboratory testing.[2] One body remained on the ship as of Wednesday, while nearly 150 passengers and crew from 23 countries isolated in their cabins to prevent further spread. The vessel, which had traveled over 6,000 miles, arrived near Cape Verde but was barred from disembarking passengers.

The Rare Threat of Hantavirus

Hantavirus typically spreads through inhalation of dust contaminated by rodent urine, droppings, or saliva, though the Andes strain identified here can rarely transmit between humans via close contact, such as sharing food or bedding.[1] Officials suspect initial infections occurred before departure from South America or at rodent-populated island stops. Symptoms include fever, muscle aches, and severe respiratory distress, with an incubation period of up to 45 days.

The World Health Organization noted that while severe, the virus does not easily pass person-to-person. WHO chief Tedros Adhanom Ghebreyesus stated, “At this stage, the overall public health risk remains low.”[2] Experts from the Dutch National Institute for Public Health dispatched two doctors to the ship, underscoring the focused response to symptomatic individuals.

Urgent Evacuations and Containment Efforts

The latest evacuations involved a 41-year-old Dutch national, a 56-year-old British national, and a 65-year-old German national, including the ship’s doctor who had been in serious condition but stabilized.[1] They were flown via air ambulance to specialized facilities in the Netherlands and Germany. Earlier, a British man had been rushed from Ascension Island to intensive care in Johannesburg, South Africa, where he remained critical but stable.

A separate case emerged in Switzerland, where a former passenger tested positive after disembarking at St. Helena; his wife self-isolated as a precaution, and authorities confirmed no wider risk.[2] South African officials traced 42 of 62 contacts from prior flights, all testing negative, though 20 remained unaccounted for, including flight crew. Passengers described an atmosphere of uncertainty but relative calm on board.

Next Steps for the Vessel and Passengers

The MV Hondius now plans a three-to-four-day voyage to Spain’s Canary Islands for medical screening and potential disembarkation, following requests from WHO and Europe’s disease control center.[4] Spain’s Health Minister Mónica García assured that the arrival “won’t represent any risk for the public,” though Canary Islands President Fernando Clavijo expressed concerns over potential dangers to locals.

Cape Verde authorities refused docking Tuesday, leaving the ship at anchor. As investigations probe possible rodent sources and transmission chains, global health bodies continue monitoring. The focus remains on safely repatriating those unaffected while treating the ill.
