A rare virus killed three passengers on the MV Hondius.
Three passengers died. Eight countries refused to help. Inside the hantavirus outbreak on the MV Hondius.
For the past week I have been collecting everything I can find about what life is actually like on board the MV Hondius. TikTok videos filmed from cabins. Instagram captions typed with nothing but ocean outside the window. Interviews given via phone from self-isolation. Press statements released by passengers who became, without wanting to, the faces of something no travel insurance policy covers.
.
I did this because the official version of this story — the one told in WHO press releases and government statements — tells you almost nothing about what it feels like to be trapped on a ship where people are dying, where no country will let you dock, and where nobody can tell you with certainty whether you are next. The numbers are clean. The reality on board is not.
But to understand what happened on the MV Hondius, you first need to go to a birthday party in Argentina.
The Party
On the evening of November 3, 2018, a 68-year-old man walked into a birthday party in the village of Epuyén, in the Patagonian province of Chubut. It was a modest gathering, around 100 people, the kind of party that happens in small communities everywhere: a table with food, people talking too loudly, someone’s grandmother in the corner. He had just started running a fever. He stayed for 90 minutes.
He sat at a table within a metre of several people. On the way to the bathroom, he passed someone in the corridor and said “Hello.” That person was later infected.
Five people who had been in contact with him developed symptoms in the following weeks. Three of them became what scientists would later call superspreaders. One of those three infected six more people through his active social life. He died 16 days after his symptoms first appeared. His wife, the third superspreader, was already feeling ill when she attended his wake. Ten more people were infected there.
By the time the outbreak was over, 34 people had been confirmed infected and 11 were dead. All from a single introduction of the Andes strain of hantavirus into one village in southern Argentina.
European health authorities filed the report and moved on. It was, after all, Argentina.
Most people have never heard of hantavirus
In Europe and the United States, it barely registers as a medical concept. This is partly because it is genuinely rare, and partly because the strains that circulate in the northern hemisphere are unpleasant but rarely fatal — the sort of thing that occasionally sends someone to hospital after cleaning out a mouse-infested barn.
The Andes strain is a different matter.
It is found almost exclusively in South America, mainly Argentina and Chile, and it is the only hantavirus known to transmit from person to person. It is carried by the long-tailed pygmy rice rat, a small, unremarkable rodent common in agricultural areas across Patagonia. Humans are typically infected by inhaling aerosolised particles from the animal’s urine, droppings or saliva. This can happen while clearing a shed, walking through tall grass, or, it now appears, visiting a landfill on the outskirts of Ushuaia with a pair of binoculars.
What the virus does once inside a human body is methodical and terrible. It begins like influenza: fever, muscle aches, fatigue, the ordinary vocabulary of feeling unwell. Then, in roughly half of cases, it moves to the lungs. The resulting syndrome causes shortness of breath and coughing that can escalate to complete respiratory failure. A significant part of the damage is caused not by the virus itself but by the body’s own immune response, which overreacts and attacks the lungs. Hantavirus infection can be lethal in up to 40 percent of cases.
There is no specific treatment. There is no vaccine. Doctors manage symptoms and hope.
Despite all of this, the WHO has classified hantaviruses as emerging priority pathogens with high potential to spark international public health emergencies. The world has simply not paid sufficient attention, because the worst strain lives in South America, and South America is far away.
Until it is not.
The Voyage
The MV Hondius left Ushuaia, Argentina on April 1. It carried 61 crew attending to 88 passengers, many of them older birdwatchers. Each had paid around $10,000 for a once-in-a-lifetime Atlantic expedition: South Georgia, Tristan da Cunha — the most remote inhabited island on earth — then north past Saint Helena toward Cape Verde and the Canary Islands.
Among the passengers was Jake Rosmarin, an American travel vlogger who had been documenting everything. I watched his early videos. Birdwatching and penguin spotting, iced lattes on board. Of Tristan da Cunha he told his followers:
“Moments like these are hard to explain, but they’re the ones that stay with you the most.”
The footage is beautiful. It is also painful to watch now, knowing what came next.
Also on board: Kasem Hato, a Jordanian travel influencer. Helene Goessaert, a Belgian woman traveling alone.
And a Dutch couple, aged 69. They had spent the previous four months on a birdwatching trip across Chile, Uruguay and Argentina before boarding in Ushuaia. One leading hypothesis, disputed by local authorities in Tierra del Fuego, is that they contracted hantavirus at a landfill on the outskirts of Ushuaia, where the long-tailed pygmy rice rat is common. They had probably been infected before they ever set foot on the ship. The incubation period for Andes hantavirus is up to six weeks. They almost certainly did not know.
The man fell ill on April 6. He died on April 11.
“The Ship Is Safe”
On the morning of April 12, Ruhi Çenet felt something was wrong before he heard a word.
The ship’s intercom clicked on. The captain’s voice filled the corridors. He had not spoken to the passengers like this before. Çenet, a 35-year-old Turkish travel vlogger, pulled out his phone and pressed record.
“This is my sad duty to inform you that one of our passengers sadly passed away last night. Tragic as it is, it was due to natural causes, we believe. And also whatever health issues he was struggling with, I’m told by the doctor, were not infectious, so the ship is safe when it comes to that. The ship is safe. This gentleman, unfortunately, succumbed to natural causes.”
Then they went to breakfast.
What happened in the twelve days after that breakfast is the story the official updates never told. Subscribers get the full account: the passengers who isolated themselves, the ones who didn't, the science of how this particular virus moves between people — and why Europe had every reason to know, and chose not to look.
