Three Dead, Five Ill in Suspected Hantavirus Outbreak on Atlantic Cruise Ship
Cape Town, South Africa — May 4, 2026
A suspected outbreak of hantavirus on the Dutch-flagged cruise ship MV Hondius has killed three people and sickened at least five others as the vessel sails through the Atlantic Ocean, the World Health Organization (WHO) confirmed Monday. The ship, currently anchored off Cape Verde, is under investigation as health authorities work to contain the rare respiratory illness.
The WHO reported one confirmed case of hantavirus, a virus typically spread through contact with rodent urine or feces, and five additional suspected cases. Among the six affected individuals, three have died, including an elderly married couple. A British national, aged 60, remains in intensive care in Johannesburg, South Africa, after falling ill near Ascension Island.
The outbreak began aboard the MV Hondius, which departed from Ushuaia, Argentina, nearly three weeks ago on a voyage that included stops in Antarctica and the Falkland Islands before heading toward the Canary Islands. The ship carried around 150 passengers at the time of the outbreak, along with a crew of approximately 70.
The first victim, a 70-year-old man, died onboard and was disembarked in Saint Helena, a British territory in the South Atlantic. His wife later collapsed at an airport in South Africa while attempting to return home to the Netherlands and died shortly after in a nearby hospital. The third fatality occurred onboard the ship in Cape Verde, with the body still aboard as authorities assess the situation.
The WHO stated that medical care and support are being provided to passengers and crew, while laboratory testing and epidemiological investigations are ongoing. The organization emphasized that hantavirus infections are rare but can be severe, causing hantavirus pulmonary syndrome (affecting the lungs) or hemorrhagic fever with renal syndrome (affecting the kidneys). There is no specific cure, though early medical intervention can improve survival rates.
The Dutch cruise operator, Oceanwide Expeditions, confirmed the ship remains anchored off Cape Verde, where local authorities are assisting but have not permitted disembarkation. Two critically ill crew members are receiving urgent medical care, while the remaining passengers and crew are under observation.
The WHO stressed that hantavirus is not typically spread between humans, though rare cases of person-to-person transmission have been documented. Authorities are working to prevent further spread while the ship remains in quarantine.
This incident underscores the global health risks posed by rare but potentially deadly pathogens, particularly in confined environments like cruise ships. The WHO continues to monitor the situation closely, coordinating with health agencies in South Africa, Cape Verde, and the United Kingdom.
