Argentine investigators now believe a Dutch couple contracted the rare hantavirus while bird-watching at a landfill in the southern city of Ushuaia, weeks before the disease tore through their expedition cruise ship, killed three passengers, and left the vessel stranded off the coast of Africa with no port willing to take it in.
The couple visited the landfill in mid-March as part of a bird-watching tour, Argentine officials told the Associated Press on Wednesday. They likely inhaled the virus from infected rodent droppings at the site, the standard transmission route for hantavirus, which spreads through contact with the feces or urine of mice and rats.
The finding, if confirmed, would mark the first recorded case of hantavirus in Ushuaia or the surrounding province of Tierra del Fuego. Authorities had previously said the region had never logged a single case. That a tourist attraction, a landfill open to bird-watchers, served as the apparent point of infection raises hard questions about local health monitoring and site management in one of the world's most popular gateways to Antarctic expedition cruises.
The 353-foot MV Hondius, operated by Oceanwide Expeditions, departed an Argentine port on March 20 for a 35-day expedition. The 70-year-old Dutch man began showing symptoms on April 6, fever, headache, abdominal pain, and diarrhea. Five days later, on April 11, he developed acute respiratory distress and died.
His death was only linked to hantavirus weeks later. In the meantime, his body remained onboard for roughly two weeks.
During that grim stretch, his wife fell ill. On April 25, she flew with her husband's body to South Africa. She died in a Johannesburg hospital. As we previously reported when the ship was first stranded off Cape Verde, the vessel carried roughly 149 people, passengers and crew, all trapped aboard as the situation deteriorated.
Over the following nearly two weeks, eight more passengers and crew members got sick. By May 2, a third passenger had died onboard.
The timeline is striking. More than three weeks passed between the first death and the third. The ship kept sailing. The body stayed aboard. And the virus kept spreading.
On Wednesday, three patients believed to be infected were evacuated from the ship, which remained anchored off Cape Verde. The patients were identified by nationality and age: a 56-year-old British national, a 41-year-old Dutch citizen, and a 65-year-old German. The World Health Organization said they were evacuated to receive medical care in the Netherlands. Two of the three are believed to be seriously ill.
The ship's doctor was also among those removed. Spain's health ministry said the doctor had been in "serious condition" but has since improved.
In Praia, Cape Verde's capital, the patients were taken from an ambulance and escorted to a waiting jet. The scene, sick passengers airlifted off a stranded cruise ship in a developing nation's capital, underscored how far the crisis had spiraled from its origins at a bird-watching stop in Patagonia.
With the evacuations underway, the WHO and Oceanwide Expeditions said the MV Hondius is now expected to port and disembark passengers in Tenerife, part of Spain's Canary Islands. That plan has triggered a political dispute in Spain.
Fernando Clavijo, the president of the Canary Islands, told reporters Wednesday that his government has not received detailed information on how the disembarkation process will be carried out. He raised fears that passengers could spread hantavirus to local residents. Earlier coverage noted that the WHO itself had warned that human-to-human transmission of the virus could not be ruled out, a statement that did little to calm nerves in potential port communities.
Representatives for Spain's central government fired back, calling Clavijo's remarks "irresponsible." Health officials have said the risk of spreading hantavirus is very low.
The clash between Madrid and the Canary Islands government is a familiar pattern: central authorities insist the science supports their plan, while the local officials who would bear the consequences of any failure demand answers they haven't received. Clavijo may or may not be right about the risk. But his complaint, that his government was not given detailed information, is the kind of procedural failure that erodes public trust in health bureaucracies everywhere.
El Pais reported that 14 Spanish nationals remain on board the vessel, adding another layer of domestic pressure on Madrid to resolve the standoff.
Hantavirus is not a household name. It is typically transmitted when people inhale particles from infected rodent droppings, urine, or nesting materials. It is not, under normal circumstances, considered easily transmissible between humans, though the WHO's earlier refusal to rule out person-to-person spread aboard the Hondius rattled that assumption.
The mortality rate can be high. Three people are already dead from this single outbreak. The speed with which the virus moved through a confined shipboard environment, eight additional cases in under two weeks, suggests that close quarters and limited ventilation may have played a role, even if the original exposure happened on land.
For travelers, the lesson is sobering. A bird-watching excursion at a landfill in a region with no recorded history of hantavirus led to an international health emergency spanning Argentina, South Africa, Cape Verde, the Netherlands, and Spain. Cruise passengers who pay premium prices for expedition voyages to remote destinations are entitled to ask what health screening, if any, was in place at the Ushuaia site, and what protocols the ship followed once the first passenger died.
The broader cruise industry has faced a string of high-profile incidents in recent months. A cruise ship ran aground near Fiji, stranding tourists. Elsewhere, vessels have navigated geopolitical flashpoints that would have been unthinkable a few years ago.
Argentine officials have offered a theory, the landfill, the rodents, the bird-watching tour, but they have not publicly detailed the evidence that led them to that conclusion. Was the virus detected in rodent samples at the site? Were other tour groups exposed? Did local health authorities know the landfill posed any risk before the outbreak?
The names of the dead have not been released. The identity of the third passenger who died onboard by May 2 remains unknown, and it is unclear whether that death has been formally confirmed as hantavirus or is simply presumed given the circumstances.
Travelers weighing international itineraries, whether by cruise ship or otherwise, face a world where regional instability and health risks can upend plans without warning. The MV Hondius passengers signed up for a 35-day adventure. They got a floating quarantine, three dead fellow travelers, and a political fight over whether any port will let them off.
When governments and health agencies cannot even agree on where to dock a ship carrying sick passengers, the system has already failed the people trapped aboard.
