What is hantavirus and how does it spread?
What do we know about the victims?
The first victim was a 70-year-old Dutchman, who suddenly fell ill on the ship with a fever, headache, abdominal pain and diarrhea, South Africa’s Health Department told CNN. He died on board on April 11, Oceanwide said Monday, adding that the cause of death couldn’t be determined on the ship. His body was disembarked at Saint Helena on April 24, to be repatriated.
The man’s wife, who was 69 years old and also Dutch, then collapsed at an airport in South Africa while trying to fly home to the Netherlands and died at a nearby hospital, the department said. “At this time, it has not been confirmed that these two deaths are connected to a current medical situation on board,” Oceanwide added.
After the ship left Saint Helena, a British national fell sick on April 27, Oceanwide said. He is now in a critical condition at private medical facility in Johannesburg, South Africa’s Health Department said, and is the only case confirmed to be hantavirus.
CNN has reached out to the British Foreign, Commonwealth and Development Office.
On May 2, a German national died on board the MV Hondius, though his cause of death has not yet been established, Oceanwide said.
And two crew members — one British and one Dutch national — are currently experiencing acute respiratory symptoms, requiring urgent care, the tour operator added. Hantavirus has not been confirmed in either case.
One passenger, travel vlogger Jake Rosmarin, spoke of the fear and uncertainty percolating through the ship on Monday.
“What’s happening right now is very real for all of us here. We’re not just a story. We’re not just headlines,” he said in a video posted on Instagram, his voice cracking with emotion.

“We’re people, people with families, with lives, with people waiting for us at home. There’s a lot of uncertainty, and that’s the hardest part.”
A medical team has begun treating those on the ship who “require specific care,” said da Luz Lima, Cape Verde’s health minister, though no decision has been made about whether to transfer the crew members to receive medical care, the tour operator said.
Dutch authorities have agreed to repatriate the symptomatic crew members, as well as the body of one deceased individual, to the Netherlands, Oceanwide Expeditions said.
The WHO said it 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 Dutch Foreign Ministry echoed that, saying it is working “to explore the possibilities of medically evacuating a few individuals from the ship.”
It’s not clear how long the ship, and its passengers, will remain off the coast of Praia. Cape Verde’s health authorities are “monitoring this situation very closely … and will provide an update as soon as possible,” the country’s health director, Angela Gomes, told local outlet RTC.
How did the outbreak occur?
Nor is it clear how the infections occurred. The Ministry of Health of Tierra del Fuego province, where Ushuaia is located, said there has never been a reported case of hantavirus in the province. However, hantavirus is endemic in other parts of Argentina and Chile, according to the WHO.
In late 2018 and early 2019, the Patagonian town of Epuyén — 1,400 kilometers (about 870 miles) from Ushuaia — experienced dozens of hantavirus infections, resulting in at least 11 deaths.."
How deadly is hantavirus?
Early symptoms include fatigue, fever and muscle aches, as well as headaches, dizziness, chills and abdominal problems in some patients. Later symptoms of hantavirus pulmonary syndrome include coughing, shortness of breath and tightness in the chest.
Hantaviruses found mostly in Europe and Asia can also lead to severe kidney disease.
There is no cure for hantavirus infection, beyond treatment of symptoms. Patients with severe breathing difficulties may need to be intubated, the CDC said.
The disease is rare but highly deadly — about 38% of people who develop respiratory symptoms may die, according to the CDC. If the patients are elderly or immunocompromised, the mortality rate could be higher, Miscovich said.
While it can be severe, “it is not easily transmitted between people,” Kluge added.
As of the end of 2023, just 890 confirmed cases of hantavirus disease have been reported in the US since surveillance began in 1993
