Cruise ship outbreak puts Ushuaia in spotlight
Argentina's southernmost city, Ushuaia, is facing scrutiny after a hantavirus outbreak on a Dutch cruise ship raised questions about whether the virus originated in the region. The MV Hondius, which departed from Ushuaia on April 1, is now anchored in Tenerife, Spain, where passengers are being evacuated. The vessel carried 114 passengers and 61 crew members from 22 countries.
Local officials reject hantavirus link
Provincial authorities in Tierra del Fuego have firmly denied that the virus originated in Ushuaia. Juan Facundo Petrina, the province's Director General of Epidemiology and Environmental Health, stated that Tierra del Fuego has no recorded hantavirus cases since the disease became notifiable in 1996.
Petrina emphasized that the region lacks the long-tailed mouse subspecies responsible for transmitting the virus and has different climatic conditions than northern Patagonia, where the disease is endemic. He also noted that the Strait of Magellan acts as a natural barrier, making it unlikely for rodents to cross into the province.
"We do not have the subspecies of the long-tailed mouse, nor do we share the same climatic conditions as northern Patagonia-neither in humidity nor temperature-for its development."

National investigation underway
Despite local assurances, Argentina's national government has dispatched a team of experts to Ushuaia to investigate potential traces of hantavirus or the presence of the long-tailed mouse. The team will collaborate with local biologists to trap and test rodents at a landfill site on the city's outskirts, a popular spot for tourists observing birds.
As of May 11, the experts had not yet arrived, and no active investigation was visible at the landfill during a recent visit. Eduardo López, an epidemiologist at Buenos Aires' Ricardo Gutiérrez Children's Hospital, stressed the need for further study, citing shifting ecosystems that may expand the habitat of disease-carrying rodents.
Economic concerns loom over tourism
Ushuaia's economy relies heavily on tourism, particularly as a departure point for Antarctic cruises. Juan Manuel Pavlov of the Fuegian Tourism Institute noted that over 95% of Antarctic voyages originate from the city's port, with more than 500 annual calls. While no official cruise cancellations have been reported, the outbreak's long-term impact remains uncertain.
Pavlov expressed optimism about the upcoming winter season but acknowledged concerns about the outbreak overshadowing tourism efforts. "We've been working hard in our main markets, and we don't want this to undermine our focus on public health," he said.
Tourists remain undeterred
Despite the uncertainty, life in Ushuaia appears unchanged. Visitors continue to explore the city's waterfront and embark on excursions to nearby attractions like Isla de los Estados and the Beagle Channel.
Adonis Carvajal, a local tour operator, said the absence of reported cases in the province has reassured travelers. "People ask about infections here, but the lack of sick individuals brings calm," he noted. "The strain may have come from the south, but it didn't originate here."
Tourists interviewed by reporters expressed confidence in their decision to visit. David Bomparp, a Venezuelan traveler from Colombia, said he and his partner proceeded with their trip after confirming no cases had been reported in Ushuaia. "We came without worrying, following safety measures," he said. Costa Rican tourist Jordan Bermúdez echoed this sentiment, stating that research before his arrival from Chile did not deter his plans.
Unanswered questions about the outbreak
Health authorities are still working to pinpoint the origin of the infection. Officials believe a Dutch couple who contracted the virus and later died may be "patient zero." Their movements through Argentina, Chile, and Uruguay are being reconstructed using border records, but no definitive source has been identified.
Chilean and Uruguayan authorities have ruled out their countries as the origin, based on the World Health Organization's estimated incubation period of one to eight weeks. Petrina suggested the couple likely contracted the virus in Argentina, possibly in northern Patagonian provinces like Chubut, Neuquén, or Río Negro.
The National Ministry of Health has not proposed a definitive theory but acknowledged that no hantavirus cases have ever been reported in Tierra del Fuego. Investigators hope the evacuation of MV Hondius passengers in Tenerife may provide new clues, though many questions remain unanswered.
