Three die on Atlantic cruise ship from suspected hantavirus; WHO investigating outbreak

THREE people have died and another three are ill after a Netherlands-based cruise ship was hit by a suspected outbreak of hantavirus, a rodent-borne virus that can cause fatal respiratory illness, authorities and media reports said on Sunday (May 3).

Netherlands-based Oceanwide Expeditions said in a news release it was “managing a serious medical situation” on a polar expedition ship, the MV Hondius, which was off Cape Verde, an island nation in the Atlantic west of Africa.

The cruise departed from Argentina about three weeks ago with around 150 passengers and stopped in the Antarctic and other locations on its way to Cape Verde, according to media reports.

A Dutch foreign ministry spokesperson confirmed that two Dutch passengers had died, but gave no further details.

The World Health Organization said in an X post that one of the sick passengers was in intensive care in South Africa. Sky News reported the passenger is British, citing South Africa’s Department of Health.

WHO said it was investigating the outbreak. Lab tests have confirmed hantavirus in one of the six people, the agency said.

Oceanwide Expeditions said Cape Verde authorities had not given permission for passengers requiring medical care to disembark, and Dutch authorities were seeking to organise repatriation of two symptomatic passengers along with the body of a deceased passenger.

Hantavirus can be spread when droppings and urine of rodents become airborne, such as when people sweep out sheds where mice have been living. WHO said the virus can be spread between people in rare cases.

The illness begins with flu-like symptoms and can lead to heart and lung failure, with around 40 per cent of cases resulting in death, according to the US Centers for Disease Control.

There are no specific drugs to treat hantavirus, so treatment focuses on supportive care, including putting patients on ventilators in severe cases.

“WHO is facilitating coordination between member states and the ship’s operators for medical evacuation of two symptomatic passengers, as well as full public health risk assessment and support to the remaining passengers on board,” the WHO said.
