  • US health officials: Hantavirus risk to Americans ‘very low’

    US health officials: Hantavirus risk to Americans ‘very low’

    U.S. national health authorities have moved to calm public anxiety after a single case of hantavirus was detected among a group of cruise ship passengers repatriated to the country. According to official statements, 18 travelers who were aboard the MV Hondius have completed their return to the United States, and routine public health screening following the voyage identified one passenger who received a positive test result for the rare rodent-borne virus.

    In the wake of the confirmation, public health leaders have moved quickly to downplay widespread concerns, stressing that the overall level of risk hantavirus poses to the general American population remains extremely low. Hantavirus infections are rare in the United States, typically transmitted to humans through contact with infected rodent droppings, urine, or saliva, rather than through sustained person-to-person spread in most common scenarios. Health agencies note they are continuing to monitor the situation and conduct follow-up with close contacts of the infected patient to prevent any potential further transmission, while urging the public to avoid unnecessary panic over the isolated case.

    A team from the British Broadcasting Corporation has launched an on-site investigation in the southern Argentine city of Ushuaia, working to unpack the origins of a dangerous hantavirus outbreak linked to the Dutch expedition vessel MV Hondius. Located on the edge of Tierra del Fuego, billed as the world’s southernmost city, Ushuaia has emerged as the key suspect in the spread of the virus that has already sickened multiple people who sailed on the vessel.

  • Hantavirus scare exposes US-China mRNA gap

    Hantavirus scare exposes US-China mRNA gap

    In late May 2026, a dramatic incident unfolded at sea that has reframed global conversations about pandemic preparedness and biotech investment: the Dutch expedition cruise ship MV Hondius, which had been adrift for weeks amid a growing public health emergency, finally docked in Tenerife. By the time the vessel reached port, three people had died from the outbreak, and eight passengers and crew had tested positive for Andes virus, a strain of hantavirus. Critically, this is the only known hantavirus variant that can spread between people. While the World Health Organization has labeled the outbreak a serious cluster, the organization has assessed the overall global risk of widespread transmission as low.

    This small but deadly scare offers more than just a reminder of emerging pathogens; it holds a valuable lesson for global health strategy that extends far beyond hantavirus itself. When any new or little-known pathogen surfaces, public discourse too often swings to unhelpful extremes: either widespread panic or outright dismissal. Hantavirus deserves neither. While it can be lethal in symptomatic cases, it does not spread at the same rate as influenza or SARS-CoV-2, the virus that caused the COVID-19 pandemic. It is precisely this low but persistent risk that makes it a perfect case study for how countries should approach future health threats.

    The core takeaway from this incident is not that the world needs to rush a hantavirus vaccine into mass distribution immediately. Instead, it highlights that modern vaccine development platforms represent a critical form of strategic health insurance – and countries around the world are now valuing this insurance in dramatically different ways.

    Hantavirus vaccine research is still in its early stages. Biotech firm Moderna has already disclosed preclinical and early-stage work on a candidate, developed in partnership with the U.S. Army Medical Research Institute of Infectious Diseases and Korea University. Still, public health experts uniformly caution that a fully approved, widely available hantavirus vaccine is likely years away without an extraordinary coordinated global push. This combination – low immediate outbreak risk, high potential catastrophic consequence, and limited commercial market incentive – is exactly the space where intentional public policy becomes indispensable.

    Against this backdrop, the growing divergence in mRNA technology strategy between China and the United States has become impossible to ignore. China has framed mRNA not merely as a short-term technology for the COVID-19 pandemic, but as a flexible, general-purpose platform that can advance everything from infectious disease control to oncology, while also supporting Beijing’s goal of biomedical sovereignty.

    Today, China’s domestic mRNA development pipeline spans multiple high-priority areas: cancer immunotherapy, influenza vaccines, respiratory syncytial virus (RSV) preventives, and countermeasures for emerging pathogens. The country has steadily expanded investment in core enabling technologies, including lipid nanoparticle delivery systems and AI-assisted antigen sequence design. In 2023, China approved its first domestically developed mRNA COVID-19 vaccine, establishing a critical domestic manufacturing baseline even though the approval came after the first major global wave of the pandemic.

    The United States, by contrast, is moving in the opposite direction. In August 2025, the U.S. Department of Health and Human Services announced it would wind down mRNA vaccine development projects administered by the Biomedical Advanced Research and Development Authority (BARDA), terminating 22 separate projects that represented nearly $500 million in public investment.

    Administration officials framed the decision as a strategic redirection, arguing that public funds would be better allocated to platforms with more proven track records against upper respiratory viruses. But many leading vaccine scientists have criticized the move as a damaging strategic retreat from a transformative technology that the United States itself originally pioneered.

    This trend is not a simple narrative of China rising and America retreating. The U.S. still retains unmatched global advantages in biomedical innovation: world-leading research universities, a rigorous regulatory system, deep capital markets, and decades of advanced manufacturing expertise. It also has legitimate policy reasons to scrutinize public spending, require rigorous evidence of efficacy, and avoid framing any single technology as a cure-all.

    For its part, China still faces significant structural challenges in expanding its mRNA ecosystem: questions around regulatory credibility, transparency of clinical data, uneven global public trust, and the ongoing difficulty of translating pipeline projects into safe, effective products that gain widespread international acceptance. Still, the divergence in long-term strategic framing between the two powers is clear and consequential.

    China’s policy approach centers on a core question: how can mRNA be embedded into a sustained long-term strategy for industrial development and national health security? The U.S. approach, by contrast, centers on a different question: how much public support for mRNA remains politically and fiscally justifiable in the aftermath of the COVID-19 pandemic? These different starting questions lead to vastly different long-term outcomes for global health.

    The deeper misstep in global discussions of mRNA is that the technology is almost always framed too narrowly. mRNA is not just a new type of vaccine. It is a programmable manufacturing platform for biological products. Once a country has established core infrastructure – reliable delivery platforms, accumulated safety data, scalable production lines, standardized quality controls, and established regulatory pathways – developing a new product for a new target can be accomplished far faster than with most traditional vaccine development approaches.

    This inherent speed does not eliminate the hard work of rigorous science. Any vaccine candidate still needs to identify the correct antigen, generate long-lasting durable immunity, prove safety through large-scale trials, and navigate clinical testing challenges that are particularly acute for rare, sporadic outbreaks. But a country that maintains a standing, robust mRNA ecosystem starts the race to counter a new threat several laps ahead of nations that treat the platform as an emergency tool to be built from scratch only after a crisis hits.

    The most productive way to frame the global mRNA conversation is to stop treating it as a narrow debate about vaccines. Instead, it is more accurately compared to the global race for semiconductor leadership. Nations do not invest billions in semiconductor design and manufacturing capacity because they know exactly which specific chips they will need a decade from now. They invest because having domestic design capacity, fabrication infrastructure, skilled talent, and resilient supply chains creates critical strategic options that can be adapted to whatever demand emerges.

    mRNA offers exactly the same kind of option value for global health. It enables faster responses to newly emerging viruses, more adaptable annual influenza vaccines, individualized cancer immunotherapies, and targeted countermeasures for threats that are too small to attract commercial investment but too dangerous to leave unaddressed.

    This is why the comparison between Chinese and U.S. strategy should not be framed as a simplistic ideological competition. Instead, it should be viewed as a lesson in institutional learning. China can learn from the U.S. model that breakthrough biomedical science depends on open inquiry, rigorous peer review, strictly controlled clinical trials, and building global public trust in data. The U.S., in turn, can learn from China that transformative platform technologies require sustained investment in long-term infrastructure, not just episodic emergency funding during acute crises.

    Both nations can benefit from the shared lesson that global biomedical leadership is not won through slogans and political posturing. It is secured through unglamorous, durable systems: a well-trained workforce, reliable public procurement pathways, transparent clinical data, flexible scalable manufacturing, and sustained public trust in health institutions.

    A balanced, effective policy approach avoids two dangerous extremes. The first is undisciplined blanket funding for every mRNA candidate, assuming all projects deserve public backing regardless of evidence. The second is a full retreat from the platform, driven by post-COVID political fatigue, unmet early expectations, or narrow metrics that obscure the broader long-term value of the ecosystem. Even the most common critique of COVID-19 mRNA vaccines – that vaccinated people could still contract and transmit the virus – misses the core point: the primary benefit of those shots was always their ability to prevent severe disease, hospitalization, and death, a goal they achieved with remarkable success.

    For countries across Asia, the implications of this divergence are immediate and actionable. Nations do not need to choose between aligning with the U.S. or Chinese model. Instead, they can pursue a middle path of building regional mRNA manufacturing capacity, participating in multinational clinical trials, requiring transparent public data from all developers, and negotiating technology partnerships that reduce dependence on any single global power. The end goal should not be divisive vaccine nationalism. It should be widespread vaccine optionality: the ability to respond rapidly to whatever threat emerges.

    It is unlikely that hantavirus will ever become the next global pandemic. In fact, the world should hope it never does. But the next unexpected pathogen, the next breakthrough cancer therapy, or the next major respiratory virus threat will test whether countries used the post-COVID years to build durable adaptive platforms – or merely spent that time re-litigating the last crisis.

    China is investing heavily as if mRNA is a core part of the world’s long-term health future. The United States would be wise to avoid treating one of its own most transformative scientific breakthroughs as nothing more than a temporary tool for wartime emergency. The real question at stake is not which country will win an mRNA race. It is whether the world will have enough trusted, distributed, and adaptable biomedical capacity when biology surprises us again. This article was written by Y. Tony Yang, an Endowed Professor at the George Washington University in Washington, DC.

  • US national on repatriation flight tests positive for hantavirus

    US national on repatriation flight tests positive for hantavirus

    A deadly hantavirus outbreak aboard the expedition cruise ship MV Hondius has triggered a coordinated global repatriation operation, with multiple nations arranging emergency evacuations after three passengers died and new positive cases were detected among returnees. The vessel, which completed a voyage through South America, is currently anchored off the coast of Tenerife in Spain’s Canary Islands, where authorities have overseen the gradual disembarkation of more than 90 international passengers since Sunday.

    The U.S. Department of Health and Human Services confirmed Monday that one American national returning on a government-chartered repatriation flight tested positive for hantavirus, while a second passenger is experiencing mild symptoms consistent with the infection. Out of an abundance of caution, both patients were transported in specialized biocontainment units during the flight. All 17 U.S. citizens on the charter, plus one British national residing in the U.S. who joined the evacuation, are now undergoing comprehensive clinical assessment and further screening at the University of Nebraska Medical Center. Seven additional U.S. passengers returned to the country earlier and are currently under active monitoring by public health officials in their home states. Officials from the U.S. have emphasized that the risk of a large-scale community outbreak remains extremely low.

    Three passengers have already died from complications linked to the outbreak: a Dutch couple and a German woman, two of whom have been officially confirmed to have contracted hantavirus. The Andes strain of hantavirus, which the World Health Organization (WHO) suspects infected passengers during a stop in South America, is most commonly carried by rodents, but limited human-to-human transmission is possible. Typical symptoms of infection include high fever, extreme muscle fatigue, body aches, abdominal pain, vomiting, diarrhea and progressive shortness of breath.

    The outbreak has sparked public disagreement between global health leaders and U.S. public health officials over safety protocols. WHO Director-General Tedros Adhanom Ghebreyesus has warned that the U.S. decision to deviate from WHO-recommended guidelines carries potential public health risks. The global health body has mandated a 42-day isolation period for all passengers disembarking the MV Hondius. However, Dr. Jay Bhattacharya, acting head of the U.S. Centers for Disease Control and Prevention (CDC), pushed back against the strict measures, saying he sought to avoid unnecessary public panic. He noted that human-to-human transmission of the virus is rare, and it should not be managed using the same strict protocols implemented during the COVID-19 pandemic.

    Photographs captured Sunday showed disembarking passengers donning full personal protective equipment, including blue medical gowns, bouffant caps and surgical face masks, as they entered the port of Granadilla de Abona in Tenerife. Multiple countries have launched their own repatriation and quarantine operations for their citizens:
    – French health authorities confirmed a French passenger who returned to Paris tested positive for hantavirus, and is currently in isolation as her health condition deteriorates. She was one of five French nationals on board the ship, and contact tracers have already identified 22 close contacts who are being monitored.
    – A charter flight carrying 20 British nationals landed at Manchester Airport on Sunday, with all passengers transported to Arrowe Park Hospital in Merseyside for a 72-hour precautionary isolation period. No passengers have reported symptoms so far, though two other British citizens with confirmed hantavirus are receiving treatment in the Netherlands and South Africa respectively.
    – Fourteen Spanish nationals repatriated to Madrid are currently undergoing mandatory quarantine at a military hospital, with two additional evacuation flights scheduled for Monday afternoon.
    – A separate flight carrying 26 passengers and crew, including eight Dutch nationals, landed in the Netherlands on Sunday. Six passengers are scheduled to travel to Australia, while another 18 will be repatriated to the Netherlands on additional flights. Both of these final flights will also carry passengers from other nations that did not arrange their own independent repatriation missions.

  • French woman evacuated from cruise ship tests positive for hantavirus

    French woman evacuated from cruise ship tests positive for hantavirus

    In recent developments linked to a global cruise evacuation operation, two passengers from the MV Hondius have tested positive for hantavirus, with one of the patients in declining health, French health authorities confirmed this week. French Health Minister Stephanie Rist shared updates with public broadcaster France-Inter on Monday, noting that the first confirmed case is a French national who was repatriated to Paris alongside four other compatriots on Sunday. The patient first began exhibiting noticeable symptoms during the return flight to the French capital, and after being admitted to a local hospital, her condition deteriorated overnight, according to Rist’s statement.

    The MV Hondius anchored off the coast of the Canary Islands earlier this week following reports of potential hantavirus exposure among those on board, prompting an international repatriation effort organized by multiple national governments. On Sunday, the first groups of passengers began departing the vessel for home aboard military and government-chartered aircraft. The disembarkation process, which was still ongoing as of Monday, saw passengers escorted from the ship to the shore of Tenerife by emergency personnel wearing full-body protective suits and filtration respirator masks to reduce the risk of virus transmission.

    Global health authorities have issued guidance for handling the evacuated passengers, with the World Health Organization recommending that all former passengers from the MV Hondius undergo close medical monitoring following their return. In response to this guidance, many countries have implemented mandatory quarantine measures for every passenger repatriated from the vessel. Late on Sunday, United States health officials confirmed a second positive case: an American national who was among 17 passengers being flown to a medical facility in Nebraska for monitoring and treatment. Unlike the French patient, this American case is currently asymptomatic, officials reported.

  • US citizen from hantavirus ship tests positive

    US citizen from hantavirus ship tests positive

    A multi-day international repatriation operation for passengers and crew of the cruise ship MV Hondius, the center of a deadly hantavirus outbreak, stretched into Monday, with U.S. health officials confirming one American passenger has tested positive for the rare virus.

    The outbreak has already claimed three lives: a Dutch couple and a German citizen, with multiple other people falling ill. Hantavirus, a pathogen most commonly carried and spread by rodents, has no licensed vaccines or targeted treatments currently available. The strain confirmed among infected people on board is the Andes virus, the only hantavirus variant capable of human-to-human transmission, a detail that has spurred global public health concern. The ship originally departed Ushuaia, Argentina in early April, where the virus is endemic.

    Despite the outbreak, global and Spanish public health officials have emphasized that the broader risk to global public health remains low, pushing back against unnecessary comparisons to the global COVID-19 pandemic. The Canary Islands regional government had initially refused to allow the vessel to dock, only granting permission for it to anchor offshore when it arrived early Sunday, with authorities stressing there would be no uncontrolled contact between evacuees and the local population of Tenerife.

    On Sunday, 94 people from 19 different nationalities were evacuated from the ship, which carries a total of nearly 150 passengers and crew spanning 23 nationalities. Spanish Health Minister Monica Garcia confirmed that all passengers who disembarked on Sunday were asymptomatic and passed a final medical screening before leaving the vessel. AFP journalists on the ground observed evacuees, clad in blue protective medical suits, disembarking at Granadilla de Abona’s industrial port before being transported via Spanish military buses in a convoy to Tenerife South Airport for repatriation flights.

    Evacuation operations were scheduled to conclude by Monday, after which the ship will refuel and depart for the Netherlands with roughly 30 remaining crew members that evening. Adverse weather forecast for later Monday forced authorities to accelerate the repatriation timeline to avoid endangering the operation.

    Even with pre-departure screenings in place, multiple countries have reported cases among evacuees. Shortly after the first evacuations began, French Prime Minister Sebastien Lecornu announced on social platform X that one of five French evacuees returning to Paris showed active hantavirus symptoms, and all five were placed into immediate strict isolation. Late Sunday, U.S. health authorities confirmed the positive mild PCR test result for one American passenger, noting a second American passenger has mild symptoms.

    By Sunday evening, repatriation flights had already carried groups of passengers to dozens of countries across the globe. A flight carrying dozens of passengers of multiple nationalities landed in the Netherlands, while other flights departed for Canada, Turkey, the United Kingdom, Ireland, and the U.S., among other destinations. A plane carrying 20 UK passengers landed in Manchester Sunday, with all passengers transferred to a Liverpool-area hospital for testing and 72 hours of quarantine. Greece’s health ministry confirmed a Greek male evacuee will complete a 45-day mandatory quarantine in an Athens hospital, while 14 Spanish citizens will isolate at a military hospital in Madrid.

    The World Health Organization has recommended a 42-day quarantine period and active daily symptom monitoring for all evacuees, per Maria Van Kerkhove, the WHO’s director of epidemic and pandemic preparedness and prevention. However, the U.S. has adopted a more flexible approach: acting CDC Director Jay Bhattacharya noted that the 17 American passengers on board would not be required to quarantine at Nebraska’s specialized medical center by default. Instead, passengers will be able to complete isolation at home based on individual risk assessment, as long as they do not put other people at risk during travel. WHO Director-General Tedros Adhanom Ghebreyesus, who was on Tenerife observing the evacuation operation, warned that this U.S. policy carries potential public health risks. A group of American passengers was expected to land in Omaha, Nebraska early Monday local time.

    Investigations into the origin of the outbreak are still ongoing. The WHO believes the initial infection occurred before the cruise departed Argentina, with subsequent spread between passengers on the cramped vessel. However, Argentine provincial health official Juan Petrina pushed back on this narrative, arguing that based on the virus’ multi-week incubation period and other evidence, the Dutch patient linked to the initial outbreak had an almost zero chance of contracting the virus in Ushuaia. Health authorities across multiple nations are currently tracking all passengers who have already disembarked the vessel, as well as any close contacts that may have been exposed to the virus.

  • What next for US passengers evacuated from hantavirus-hit cruise ship?

    What next for US passengers evacuated from hantavirus-hit cruise ship?

    A coordinated international public health response is underway after a potential hantavirus exposure on a cruise ship docked in Spain’s Canary Islands, with 17 American passengers and one British resident of the U.S. being repatriated via government charter jet for specialized screening and quarantine at a leading U.S. medical facility.

    The passengers were part of the more than 90 people evacuated from the MV Hondius on Sunday at the Port of Grandilla de Abona on the island of Tenerife. Photographs captured the group disembarking the vessel wearing full personal protective equipment, including disposable blue gowns, bouffant caps, and medical-grade face masks. Seven other U.S.-based passengers had returned to the country earlier and are already undergoing routine monitoring in their home states across the nation.

    Upon arrival early Monday morning at the University of Nebraska Medical Center (UNMC) in Omaha, the newly repatriated group will undergo formal risk assessment by public health officials to determine if they require treatment or can safely complete monitoring protocols, acting Centers for Disease Control and Prevention (CDC) Director Jay Bhattacharya confirmed to CNN.

    Officials stress that the overall risk of a large-scale hantavirus outbreak remains extremely low, and the public should not confuse this event with the rapid spread of COVID-19. Hantavirus only spreads between people through close, prolonged contact with an infected individual who is already showing active symptoms, meaning most exposed passengers face minimal public health risk.

    “ If they weren’t in close contact with someone who was symptomatic, then we’re going to deem them a low risk. If they were in close contact, we’re going to deem them a medium or high risk,” Bhattacharya explained. Tailored protocols will apply for each risk tier, he noted: low-risk passengers may be allowed to return home via controlled, isolated transportation to avoid exposing other members of the public, while higher-risk individuals will be offered the option to complete their quarantine period at the Nebraska facility. All passengers, regardless of risk classification, will complete a 42-day self-isolation period and ongoing monitoring by local health departments, with full CDC support throughout the process.

    Notably, none of the evacuated passengers are currently showing active symptoms of hantavirus infection, so broad testing is not being conducted at this time per CDC guidance.

    UNMC was selected for this operation because it houses the United States’ only federally funded national quarantine facility: a 20-bed National Quarantine Unit that opened in November 2019, just months before the onset of the COVID-19 pandemic. The facility is purpose-built for infection control, with all rooms fitted with negative air pressure systems designed to prevent the airborne spread of communicable pathogens. If any passenger does develop symptomatic hantavirus infection during their stay, they will be transferred to UNMC’s on-site Nebraska Biocontainment Unit, a specialized facility purpose-built to treat patients with high-consequence infectious diseases.

    UNMC leadership emphasized that the incoming passengers are not expected to be severely ill. “We don’t expect to see any of these passengers transported off on a gurney,” said Professor John Lowe, the center’s director. “They’re going to walk off a plane and walk into a vehicle and get driven over here and head into their quarantine room.”

    Dr. Michael Wadman, director of the National Quarantine Unit, added that the experience of quarantine for most passengers will be far from restrictive. “It’s pretty much like living in a hotel room with delivery of food. They can use their exercise devices in the room, we do daily symptom and monitoring as well as vital sign checks,” he explained, noting that passengers retain significant personal freedom during their stay.

    The seven U.S. passengers who returned earlier are currently being monitored by state health departments across the country: two are in Georgia, two in Texas, one in Virginia, one in Arizona, and an additional group is being monitored in California, with no reported symptomatic cases to date. Public health officials have repeatedly stressed that they are following decades-old, proven hantavirus containment protocols that have successfully limited past outbreaks, and there is no cause for widespread public panic. “This is not Covid. And we don’t want to treat it like Covid. We don’t want to cause a public panic over this. We want to treat it with the hantavirus protocols that were successful in containing outbreaks in the past,” Bhattacharya said.

  • Tourist hotspot at ‘end of the world’ denies causing hantavirus outbreak

    Tourist hotspot at ‘end of the world’ denies causing hantavirus outbreak

    Nestled at the southernmost tip of Argentina, Ushuaia has built its global reputation as the dramatic “End of the World” — a premier gateway for Antarctic expeditions and a starting point for explorers seeking the raw, untamed beauty of Patagonia’s landscapes. But in recent weeks, the popular tourist hub has been thrust into an unwanted spotlight, linked to a hantavirus outbreak that has spread to the Dutch cruise ship MV Hondius, currently anchored off Spain’s Canary Islands where all passengers and crew are being evacuated and repatriated.

    The MV Hondius departed Ushuaia, located in Argentina’s Tierra del Fuego province, on April 1 on a voyage that would end with an outbreak that has already claimed two lives. With 114 passengers and 61 crew members from 22 nations on board, public health investigators have operated under the working theory that the virus was introduced to the vessel during its stop in Ushuaia. But despite widespread media speculation, the exact origin of the infection and the full chain of transmission remain shrouded in uncertainty.

    The most prominent unconfirmed hypothesis, shared by anonymous Argentine officials with multiple media outlets, points to a popular birdwatching landfill on Ushuaia’s outskirts, where accumulated waste attracts large populations of rodents. But local health authorities have pushed back hard against this theory, emphasizing that Tierra del Fuego has no documented history of hantavirus infections anywhere in the province’s records.

    Juan Facundo Petrina, Tierra del Fuego’s Director General of Epidemiology and Environmental Health, has repeatedly defended his province against the ground zero claims in all recent press briefings and interviews. “In Tierra del Fuego we have no record of hantavirus cases in our history,” Petrina stated. “And specifically, since 1996 — when the National Surveillance System included it among mandatory reporting diseases — we haven’t had a single case in Tierra del Fuego.”

    Petrina, who took up his role in 2021 amid the COVID-19 pandemic, noted that the established endemic zone for hantavirus in Argentina sits more than 1,500 kilometers north of Tierra del Fuego, and the province lacks the conditions to support the disease’s primary vector. “To begin with, we do not have the subspecies of the long-tailed mouse which transmits the disease, nor do we share the same climatic conditions as northern Patagonia — neither in humidity nor temperature — for its development,” he explained. “And if rodents were to start moving, since they don’t respect geographical boundaries, it’s important to remember that we are an island. They would face the limitation of crossing the Strait of Magellan in order to infect local species, so that is an additional difficulty, beyond the climate.”

    Based on the World Health Organization’s estimated 1- to 8-week incubation period for hantavirus, Petrina estimates the original infection likely occurred between February 16 and March 13 — several weeks before the couple at the center of the outbreak arrived in Ushuaia. He believes the pair, a Dutch national who later died from the virus and is considered the likely patient zero, most likely contracted the disease in a northern Patagonian province such as Chubut, Neuquén or Río Negro. Chilean and Uruguayan health authorities have already ruled out their territories as the origin, based on the couple’s travel timeline.

    While many epidemiologists share Petrina’s skepticism that the outbreak began in Tierra del Fuego, Argentina’s national government has still authorized a team of specialist investigators to travel to the province to test for viral traces and confirm whether the disease-carrying rodent subspecies has expanded its range to the region. The team will collaborate with local biologists to trap rodents at the Ushuaia landfill and run hantavirus tests. Two days after the investigation was announced, however, the national expert team had not yet arrived, and a BBC visit to the site found no active testing or trapping underway.

    Eduardo López, head of the Department of Medicine and Infectious Diseases at Buenos Aires’ Ricardo Gutiérrez Children’s Hospital, argues that expanded investigation is still a necessary step, as shifting ecosystems have already altered rodent ranges across Argentina. “The case requires more study because ecosystems are changing,” López noted. “For example, the long-tailed pygmy rice rat, whose original habitat was the Patagonian Andes and north-western Argentina, can now be found in the province of Buenos Aires alongside other rodents that transmit the disease.”

    Beyond the public health urgency, resolving the origin question carries major economic stakes for Tierra del Fuego. Argentina’s youngest and least populated province relies on a mix of hydrocarbon extraction, fishing and tourism for its livelihood, and the cruise sector supporting Antarctic expeditions is a core economic pillar. Juan Manuel Pavlov of the Fuegian Tourism Institute confirms that more than 95% of all Antarctic-bound ships depart from Ushuaia’s port, with more than 500 vessel calls each year making the cruise industry fundamental to the provincial economy.

    To date, no official cruise cancellations have been recorded, though the industry’s summer season ended in mid-April, so any long-term impact on future bookings may not emerge for months. Local tourism stakeholders are pushing forward with preparations for the upcoming winter season, which they expect to be a strong one after years of investment in marketing and public safety protocols.

    On the ground in Ushuaia, daily life and tourist activity have continued largely as normal. Visitors still stroll the waterfront, book short excursions to landmarks like the iconic End of the World lighthouse on Isla de los Estados, and cruise the Beagle Channel. Tour operators report that the lack of local confirmed cases has helped keep visitor anxiety low.

    “The absence of cases here is very reassuring,” said Adonis Carvajal, an employee at a local tour operator. “People ask whether there are infections in the province, and the fact there are no reports of sick people here brings calm. The strain may be from the south — that’s not denied — but it didn’t originate here.”

    Many current tourists echoed that sentiment, saying they proceeded with their long-planned trips after confirming no local cases had been confirmed. David Bomparp, a Venezuelan expat living in Medellín, Colombia, who arrived in Ushuaia with his partner Daniela Sandoval just days after the outbreak news broke, said the couple decided not to cancel after checking official updates. “We planned this trip back in October, and only the day before boarding the plane did we find out what had happened,” Bomparp said. “As far as we understood, nothing had been confirmed here, so we came without worrying, following safety measures.”

    Sandoval added that while her mother was panicked enough to send constant worried updates through social media, she remained unconcerned by the unconfirmed claims. “I told her not to worry because there were no confirmed cases here,” she said. Costa Rican tourist Jordan Bermúdez, whose group traveled to Ushuaia from Chile’s Punta Arenas earlier this month, said the group researched the outbreak before departing and opted to keep their plans. “We arrived, found the city quite calm, did all the tours we had planned, and we think everything is normal,” Bermúdez said.

    Argentina’s National Ministry of Health has so far declined to endorse a definitive origin theory, noting that while a Tierra del Fuego origin cannot be completely ruled out, the province’s 27-year history of zero confirmed hantavirus cases is a critical contextual detail. Investigators hope that testing of passengers and crew evacuated from the MV Hondius in Tenerife will yield new genetic clues that help narrow down the virus’s origin. For now, however, with patient zero deceased and the couple’s full travel timeline not fully reconstructed, key questions about how the outbreak began remain unanswered.

  • French national shows symptoms on return from hantavirus-hit ship

    French national shows symptoms on return from hantavirus-hit ship

    A global public health emergency has unfolded after a hantavirus outbreak on the Dutch-operated cruise ship MV Hondius left three people dead and triggered a coordinated multinational repatriation operation off the coast of the Canary Islands. On Sunday, authorities began the carefully planned process of evacuating more than 90 of the 150 total passengers and crew from the anchored vessel, with repatriation flights scheduled for multiple nations through the following day.

    French Prime Minister Sebastian Lecornu confirmed one French national developed visible hantavirus symptoms mid-flight during a chartered repatriation trip from Tenerife to Paris. As a precautionary measure, all five French passengers evacuated from the ship were placed into immediate strict isolation upon landing at Le Bourget Airport. Photos from the scene show airport officials in full personal protective equipment (PPE) waiting on the tarmac to greet the plane, before ambulances transported the group to Paris’ Bichat-Claude Bernard Hospital. According to an official statement from France’s Ministry for Europe and Foreign Affairs, the five passengers will undergo a mandatory 72-hour quarantine and full medical assessment at the hospital, followed by a 45-day period of at-home self-isolation.

    Other nations have also implemented strict public health protocols for their returning citizens. Fourteen Spanish nationals evacuated Sunday were flown to Madrid and placed into mandatory quarantine at a military hospital in the capital. A plane carrying 26 passengers and crew, including eight Dutch citizens, landed safely in the Netherlands, while all British nationals repatriated on Sunday arrived in Manchester. The UK Health Security Agency (UKHSA) confirmed no British passengers have reported symptoms to date, but all are under active monitoring. British evacuees will spend up to 72 hours in a government isolation facility for assessment before being cleared to complete quarantine at a location suited to their living situation. Repatriation flights for Turkish, Irish and US citizens were scheduled for the same Sunday, with an additional flight bound for Australia set to depart on Monday. Spanish Health Secretary Javier Padilla confirmed all passengers and crew will be repatriated by the end of Sunday, excluding the group heading for Australia.

    The coordinated evacuation operation, developed jointly by the Spanish government and the World Health Organization (WHO), launched shortly after 7 a.m. local time Sunday, when the MV Hondius anchored in Granadilla port. Witness footage shows passengers on the vessel’s deck and at portholes all wearing white medical face masks as evacuation got underway. Passengers on the first evacuation shuttle maintained social distancing as they approached shore, where officials in full white protective suits were waiting to receive them. Some British passengers, wearing blue PPE en route to the airport, waved and gave thumbs-up to assembled media parked along their transport route.

    The outbreak has sparked local pushback, with the Canary Islands’ regional president publicly voicing concerns about the risk of local transmission on Tenerife, where the ship anchored.

    Hantaviruses are primarily carried by wild rodent populations, but the Andes strain linked to this outbreak — which the WHO confirms passengers contracted during a port of call in South America — can spread between humans. Common hantavirus symptoms include high fever, severe muscle and body aches, extreme fatigue, gastrointestinal distress including stomach pain, vomiting and diarrhea, and progressing shortness of breath that can lead to life-threatening respiratory complications.

    The outbreak has already claimed three lives: the first death was recorded on April 11, a second on May 2, and the third victim was a 69-year-old Dutch woman who disembarked the ship at St. Helena on April 24, dying in South Africa two days later. Two confirmed cases in British men are currently receiving treatment in the Netherlands and South Africa respectively, while a third British man with a suspected case is being treated on the remote Atlantic island of Tristan da Cunha. British Army medics parachuted onto the island to deliver critical medical supplies for the patient’s care.

    Once all passengers and crew have disembarked, the MV Hondius will sail to the Netherlands, where the body of the deceased passenger and their personal belongings will undergo full disinfection before being removed from the vessel.

    French evacuee from hantavirus-hit ship has ‘symptoms’: French PM

    A major public health response has been activated in France after one of five French citizens repatriated from the hantavirus-outbreak cruise ship MV Hondius has developed symptoms consistent with the rare virus, according to French Prime Minister Sebastien Lecornu. The five passengers were flown back to France on Sunday, following a deadly outbreak that has already claimed three lives on the vessel anchored off Spain’s Tenerife Island.

    In an official post on social platform X, Lecornu confirmed that one individual began showing signs of the illness mid-flight during repatriation. “These five passengers have immediately been placed in strict isolation until further notice,” the prime minister wrote, adding that all five are already receiving targeted medical care and will undergo comprehensive diagnostic testing and full health screenings to confirm their status. Lecornu also announced plans to sign an official executive decree later the same day to formalize enforceable public health isolation protocols designed to limit any potential community spread and protect the general French public.

    AFP journalists on the ground confirmed that the evacuation flight carrying the five French passengers touched down at Paris’ Le Bourget Airport, located north of the capital, shortly before 4:30 pm local time (1430 GMT). Minutes after landing, the group was transferred to a fleet of five dedicated ambulances and transported under heavy police escort to Paris’ Bichat Hospital, a leading facility for infectious disease care, an AFP photographer documented.

    The evacuation of all passengers from the MV Hondius began early Sunday, after an outbreak that has killed three people – a Dutch married couple and a German woman – and sickened multiple others with the rare virus, which is most commonly carried by rodent populations. Repatriation flights have been coordinated to move passengers to their home countries or to specialized medical facilities in the Netherlands for urgent screening, with additional flights carrying passengers bound for the United Kingdom, Canada, Ireland, Turkey, the United States and other nations continuing through Sunday.

    Prior to departure from Tenerife, one French passenger, Roland Seitre, told reporters that the planned 72-hour pre-release quarantine did not concern the group. “We haven’t had any cases on board since the end of April and nobody is sick,” Seitre said. The original protocol called for a 72-hour in-facility quarantine for full medical evaluation, followed by an additional 45 days of at-home supervised monitoring. However, Lecornu’s confirmation of a symptomatic passenger indicates French public health officials are set to implement stricter, more expansive containment measures than initially planned.

    That shift aligns with earlier guidance released Sunday in a joint statement from France’s foreign and health ministries, which explicitly outlined that any repatriated individual developing symptoms would immediately be reclassified as a “suspect case” and moved to a specialized medical facility for full evaluation and treatment. Later Sunday afternoon, Lecornu convened an emergency high-level meeting with top cabinet ministers and senior public health leaders at his office to coordinate the response to the repatriated group. Attendees included Health Minister Stephanie Rist, Interior Minister Laurent Nunez and Foreign Minister Jean-Noel Barrot, with Lecornu noting that the health minister would release a full public update on the situation later that evening.

    The World Health Organization (WHO) has classified all former passengers of the MV Hondius as “high-risk” contacts, requiring a full 42 days of continuous medical monitoring – a timeline that matches the virus’ maximum six-week incubation period. Of particular global concern is the confirmation that the strain detected in positive cases on the ship is the Andes virus, the only known hantavirus variant capable of person-to-person transmission. Despite the elevated risk, WHO officials have moved quickly to downplay comparisons to the 2020 COVID-19 pandemic, stressing that the current outbreak poses far lower overall public health risk at a global scale.
