Three Dead in Suspected Hantavirus Outbreak on Cruise Ship
Three passengers have died and at least three others are ill in a suspected hantavirus outbreak aboard the MV Hondius, an expedition cruise ship currently anchored off Praia, the capital of Cape Verde. The World Health Organization confirmed the situation Sunday.

Of the six symptomatic individuals, just one case of hantavirus infection has been confirmed in a laboratory so far, while the other five are suspected cases, the WHO said.
Two crew members, one British and one Dutch national, are currently experiencing acute respiratory symptoms requiring urgent care, according to ship operator Oceanwide Expeditions.
Dutch couple among the dead
Two of the deceased were a married couple. A 70-year-old Dutch man died onboard on April 11 and was declared dead on arrival to the remote Atlantic island of Saint Helena on April 24. His 69-year-old wife collapsed at Johannesburg’s international airport while attempting to fly home to the Netherlands and died there.
Oceanwide Expeditions said at the time that it had not confirmed whether the couple’s deaths were connected to the onboard outbreak.
The third victim was a German national, although the official cause of death has not been established, Oceanwide said.
One confirmed hantavirus case
After the ship left Saint Helena, a British national fell sick on April 27. He is now in critical condition at a private medical facility in Johannesburg and is the only case confirmed to be hantavirus, according to South Africa’s Health Department. The UK’s Foreign Office said it is monitoring the situation and is in touch with the cruise company and local authorities.
Oceanwide Expeditions said 149 people remain onboard, including 17 Americans. They will not be allowed to disembark in Cape Verde, the island nation’s health minister told Radio Cabo Verde. The ship is considering sailing to Las Palmas or Tenerife in the Canary Islands for disembarkation.
How hantavirus spreads
Hantavirus is most commonly spread when infected rodents’ urine, saliva, or droppings dry out and become airborne, and humans become infected by inhaling the contaminated particles, according to the WHO. There is no dedicated treatment or cure, though early detection improves the odds of survival. Unlike norovirus, which is commonly reported on cruise ships, hantavirus cases at sea are essentially unheard of.
The WHO stressed there is no need for alarm. “The risk to the wider public remains low. There is no need for panic or travel restrictions,” WHO Regional Director for Europe Dr. Hans Henri P. Kluge said.
“Detailed investigations are ongoing, including further laboratory testing and epidemiological investigations. Medical care and support are being provided to passengers and crew,” the WHO said.
The MV Hondius, operated by Netherlands-based Oceanwide Expeditions, departed Ushuaia, Argentina and made stops in Antarctica and Saint Helena before anchoring off Cape Verde. The ship has a passenger capacity of 170.
