This is not coronavirus. This is a very different virus.
Before anyone knew a virus was moving among them, passengers from a dozen nations stepped off an expedition cruise ship and returned to their lives — carrying with them, in some cases, a rare and deadly infection. The MV Hondius became the site of a hantavirus outbreak that killed three people and sickened at least eight, setting off a global contact-tracing effort that now spans continents. Health authorities are working to locate and monitor those who disembarked before the outbreak was detected, while international organizations remind a watchful public that this moment, though grave, is not the prelude to a pandemic.
- Three people are dead — a Dutch couple and a German national — and at least eight others infected after hantavirus spread silently aboard an expedition cruise ship before anyone raised an alarm.
- Because passengers from more than a dozen countries disembarked at a remote South Atlantic island weeks before the first confirmed case emerged, health officials are now racing to find people who have long since scattered across the US, Canada, Europe, and beyond.
- The Andean strain of hantavirus can, in rare cases, pass between people — a detail that sharpened the urgency when a KLM flight attendant who assisted a dying passenger was hospitalized showing possible symptoms.
- States from Georgia to California and countries from Switzerland to Denmark are conducting health checks, issuing isolation advisories, and monitoring returning travelers, turning a cruise itinerary into an international contact map.
- The WHO and CDC are working to contain both the virus and the fear, stressing that public risk remains extremely low — while quietly preparing guidance for the dozens of passengers still aboard as the ship approaches the Canary Islands.
On a Thursday in early May, health authorities across multiple continents began the difficult work of finding people they had not known to look for. The MV Hondius, an expedition cruise ship, had been carrying a hantavirus outbreak for weeks before anyone detected it — and by the time the first confirmed case emerged, passengers from at least twelve countries had already gone home.
Three people died: a Dutch woman who became so ill mid-flight from Johannesburg that she was removed from a KLM plane before she could reach home, her husband who had sailed with her since April 1, and a German passenger. Three others were evacuated from the ship and hospitalized in the Netherlands and Germany. Among them was expedition guide Martin Anstee, who spoke to reporters from his hospital bed, describing his condition as manageable but still uncertain.
The geographic complexity of the outbreak was staggering. A port stop at St. Helena on April 24 — before the virus was known to be present — had allowed passengers to disperse worldwide. American states including Georgia, Arizona, California, and Texas were tracking returning residents. Canada was monitoring three citizens, one of whom had shared a flight with a symptomatic person. Switzerland, Denmark, and France were each following their own cases or contacts.
Adding to the concern was the nature of the strain involved. The Andean variant of hantavirus can, in rare circumstances, spread person to person — a fact that became relevant when a KLM flight attendant who had assisted the dying Dutch woman was hospitalized in Amsterdam with possible symptoms.
Public health leaders moved quickly to prevent alarm from outpacing the facts. The WHO's Maria Van Kerkhove was direct: this was not a coronavirus-like scenario, and the risk to the general public remained extremely low. As the ship approached the Canary Islands with dozens of asymptomatic passengers still aboard, the WHO was preparing disembarkation guidance, and the ship's operator was reconstructing a full passenger manifest stretching back to March 20 — the quiet, methodical work of trying to draw a boundary around something that had already crossed many.
On Thursday, health authorities across the globe began a coordinated effort to track hundreds of people who had stepped off a cruise ship before anyone realized a virus was spreading among those aboard. The MV Hondius, an expedition vessel, had become the site of a hantavirus outbreak that would ultimately claim three lives and sicken at least eight others—five confirmed cases and three more suspected.
The dead included a Dutch couple and a German national. The Dutch woman had become so ill during a flight from Johannesburg on April 25 that KLM airline staff removed her from the plane; she died before reaching home. Her husband, who had boarded the ship with her on April 1, also succumbed to the infection. The third fatality was a German passenger. Three patients were evacuated from the vessel on Wednesday—two were admitted to hospitals in the Netherlands, while a third was transferred to Germany for treatment. Martin Anstee, an expedition guide who was among those evacuated, told reporters from his hospital bed in the Netherlands that he was managing but still undergoing extensive testing.
The challenge facing public health officials was one of geography and timing. The ship had made a stop in St. Helena, a remote island in the South Atlantic Ocean, on April 24—before anyone knew the virus was present. Passengers from at least twelve countries disembarked there, including seven British citizens and six Americans. The first confirmed case did not emerge until early May, by which time those travelers had already scattered across the world. Now, authorities in the United States, Canada, Europe, and elsewhere were attempting to locate and monitor them. Georgia was watching two asymptomatic residents who had returned home. Arizona was tracking one. California was monitoring several. Texas had identified two residents who had come back before the outbreak was detected. In Canada, three citizens who had been on the ship were under observation, including one who had shared a flight with a symptomatic person. A Danish passenger had returned home and was advised to isolate as a precaution. A Swiss man who had traveled on the Hondius tested positive after being admitted to a hospital there. A French citizen who had been in contact with an ill person was also being monitored.
Hantavirus is typically transmitted by rodents, but the Andean strain found in several victims can, in rare cases, spread from person to person. This possibility added urgency to the tracking effort. A KLM flight attendant who had been near the Dutch woman during her medical crisis was admitted to a hospital in Amsterdam showing possible symptoms of the infection. Dutch authorities were conducting daily health checks on crew members and passengers who had assisted the woman.
The World Health Organization moved to calm public concern, emphasizing that the risk to the general population remained extremely low. Maria Van Kerkhove, the WHO's director of epidemic and pandemic management, drew a deliberate distinction at a press conference: "This is not coronavirus, this is a very different virus. This is not the same situation we were in six years ago." The U.S. Centers for Disease Control and Prevention echoed that assessment, saying the risk to Americans was extremely low, though the agency was monitoring developments closely.
The immediate question facing health officials was what would happen when the ship reached the Canary Islands on Saturday or Sunday. Dozens of passengers remained aboard, none currently showing symptoms, and the WHO was preparing step-by-step guidance for their disembarkation and travel home. Oceanwide Expeditions, the ship's operator, had begun the painstaking work of establishing a complete record of everyone who had boarded and disembarked at various stops since March 20. The outbreak had transformed a routine expedition cruise into an international contact-tracing operation, with health authorities in multiple nations now waiting to see whether the virus would spread further or whether the cases already identified would mark the extent of the damage.

Why does a virus that usually comes from rodents suddenly appear on a cruise ship in the middle of the ocean?
That's the unsettling part—we don't know exactly how it got there. Hantavirus is typically found in rodent droppings, but the ship had to have been contaminated somehow, or someone brought it aboard. Once it was there, the close quarters of a ship made it easy to spread.
And the fact that it can spread person-to-person in rare cases—how worried should people actually be?
The WHO is being careful to say the risk is low, and they mean it. This isn't like COVID. But "rare" doesn't mean impossible, which is why they're tracking everyone who left the ship. One flight attendant is already in the hospital with symptoms after being near a sick passenger.
So the real problem is that hundreds of people scattered across the globe before anyone knew there was a problem.
Exactly. The ship stopped in St. Helena on April 24, people got off and flew home to a dozen different countries, and the first confirmed case didn't show up until early May. By then, those passengers were already back in their lives—on planes, in their homes, around their families.
What happens now with the people still on the ship?
They're heading to the Canary Islands this weekend. None of them have symptoms yet, but health officials are preparing detailed guidance for how they'll disembark and travel home safely. It's a waiting game at this point.
Has anyone else gotten sick besides the people already identified?
Not that we know of yet. But authorities in multiple countries are monitoring people who were on the ship or had contact with sick passengers. A lot of asymptomatic people being watched, a lot of tests being done. The next week or two will tell us whether this stays contained or spreads further.
