PRAIA, Cape Verde (AP) — Three patients with suspected hantavirus infections were being evacuated from a cruise ship to the Netherlands on Wednesday, the U.N. health agency said, as the vessel at the center of a deadly outbreak remained off Cape Verde with nearly 150 people on board waiting to head to Spain’s Canary Islands.

Associated Press footage showed health workers in protective gear heading to the ship for the evacuation that included the ship's doctor, who Spain's health ministry said had been in “serious condition” but has improved. An air ambulance later departed.

Three people have died, and one body remained on the ship, the World Health Organization said. Eight cases have been recorded in all, three of them confirmed by laboratory testing.

Contact tracing had begun on two continents, Europe and Africa, in search of infections around people who earlier left the ship, which departed over a month ago from South America for stops in Antarctica and several remote Atlantic islands. Hantavirus usually spreads by inhaling contaminated rodent droppings and can spread person-to-person, though the WHO calls that rare.

Two Argentine officials investigating the origins of the outbreak said the government’s leading hypothesis is that a Dutch couple contracted the virus during a bird-watching outing in the city of Ushuaia before boarding.

They said the couple visited a landfill during the tour and may have been exposed to rodents. The officials spoke on condition of anonymity because they were not authorized to brief the media, with the investigation ongoing. Authorities previously said Ushuaia and surrounding Tierra del Fuego province had never recorded a hantavirus case.

Officials say those still on board show no symptoms

The Dutch foreign ministry said the three people evacuated were a 41-year-old Dutch national, a 56-year-old British national and a 65-year-old German national who would be "immediately transferred to specialized hospitals in Europe.” A Dutch hospital confirmed it would take one, and German authorities said they were preparing for a second.

Two “remain in a serious condition," Dutch ship operator Oceanwide Expeditions said, and the third had no symptoms but was “closely associated” with a German passenger who died on the MV Hondius ship on May 2.

Health officials said passengers and crew members still on the ship are without symptoms. Their journey to the Canary Islands will take three or four days, Spain’s health ministry said, adding that the arrival “won´t represent any risk for the public."
