Three Dead in Hantavirus Outbreak on Atlantic Cruise Ship MV Hondius

Three people have died, and at least one confirmed case of Hantavirus has been reported among passengers aboard a cruise vessel sailing in the Atlantic Ocean, the World Health Organization (WHO) said on Sunday. According to the WHO, six individuals have been affected in the incident. Three fatalities have been recorded, while another patient is in intensive care in South Africa. Although the WHO did not officially name the vessel, sources familiar with the situation identified it as the MV Hondius, which was reportedly travelling from Argentina to Cape Verde.

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

Authorities are also providing support to remaining passengers on board as investigations continue.

A spokesperson for the Dutch government confirmed that two Dutch nationals were among the deceased, while media reports indicate that a British tourist is currently receiving treatment in South Africa. The UK’s Foreign Office said it is closely monitoring the situation and remains in contact with both the cruise operator and local authorities.

The MV Hondius is a 107.6-metre polar expedition cruise ship designed to carry around 170 passengers in 80 cabins. It typically hosts approximately 150 tourists, along with dozens of crew members, guides, and onboard medical staff. The vessel is popular among bird watchers and adventure tourists, with some specialised voyages costing up to US$18,000 per person.

Hantavirus is a rare but potentially fatal disease primarily transmitted through contact with the urine, droppings, or saliva of infected rodents such as rats and mice. Symptoms can include fever, fatigue, muscle aches, and, in severe cases, respiratory complications. While human-to-human transmission is uncommon, the WHO notes that it can occur in rare circumstances.

“There is no specific cure for hantavirus infection,” a public health expert said. “However, early diagnosis and supportive care significantly improve survival chances.”

The outbreak has raised concerns about disease control in confined environments such as cruise ships, where infections can spread rapidly if not contained. Health authorities are now focused on tracing contacts, isolating symptomatic individuals, and ensuring proper sanitation measures on board. Experts say the incident highlights the importance of strict hygiene protocols and monitoring in international travel settings, particularly in remote or expedition-style cruises.

The WHO said it will continue working with international partners to assess the public health risk and coordinate response efforts. Passengers and crew are being closely monitored, with further updates expected as more information becomes available.
