Three people have died and five others are suspected of being infected in a hantavirus outbreak on the MV Hondius cruise ship sailing in the Atlantic Ocean, the World Health Organization (WHO) confirmed on Sunday. The ship, operated by Dutch-based tour company Oceanwide Expeditions, was traveling from Ushuaia, Argentina, to Cape Verde when the outbreak occurred.
Core Facts and Immediate Action
The WHO confirmed one laboratory-verified case of hantavirus infection, a virus typically transmitted through contact with infected rodents' urine or feces. Three individuals have died, including a 70-year-old passenger who succumbed on board, and a 69-year-old British national is currently in intensive care in Johannesburg, South Africa. The ship's first fatality was a Dutch passenger, whose body is now on Saint Helena, a British territory in the South Atlantic. His 69-year-old wife, also a passenger, died in a Johannesburg hospital.
Deeper Dive and Context
The WHO is coordinating an international public health response, including medical evacuations and virus sequencing. The agency noted that while hantavirus is rarely transmitted between humans, it can cause severe respiratory illness. The MV Hondius, a 107.6-meter polar cruise ship, accommodates 170 passengers and 57 crew members. South African health authorities reported the first symptoms appeared in a 70-year-old passenger, who died on board. Discussions are ongoing about isolating two other symptomatic passengers in Cape Verde before the ship continues to Spain's Canary Islands.
Transmission and Symptoms
Hantaviruses are typically spread through environmental exposure to rodents, though rare human-to-human transmission has been documented. The viruses can cause hantavirus pulmonary syndrome or hemorrhagic fever with renal syndrome, both of which can be fatal. The WHO emphasized the importance of careful monitoring and support for affected individuals.
International Response
The UK Foreign Office is monitoring the situation and ready to support British nationals affected by the outbreak. The WHO is working with member states and the ship's operators to manage the public health event, including evacuating symptomatic passengers and conducting a risk assessment.
