Nearly a month after the first hantavirus fatality was recorded on the expedition cruise ship MV Hondius, the vessel is finally nearing Granadilla Industrial Port on the Spanish island of Tenerife, in the Canary Islands archipelago, to launch one of the most complex public health and repatriation operations in recent European history.

Spanish health and emergency authorities have spent weeks finalizing intensive preparedness protocols to receive the ship and coordinate the safe disembarkation and repatriation of more than 100 passengers and crew trapped at sea after multiple ports denied the vessel entry following the outbreak. Though the MV Hondius is expected to enter the waters off Tenerife before dawn Sunday, strict isolation rules will remain in force from the moment it approaches the coast: a 1-nautical-mile security perimeter will be enforced around the vessel, and it will anchor offshore at the port rather than docking directly to contain any potential spread of the rare Andes hantavirus strain, which has already claimed three lives on board.

Spanish Health Minister Mónica García has labeled the multi-national operation unprecedented, noting that 23 countries are involved in coordinating repatriation efforts. The meticulous planning has been tailored in part to address widespread public concern among Tenerife residents, who have expressed anxiety over bringing a vessel carrying a dangerous virus to their island. Canary Islands President has openly stated he will not feel at ease until every person on board has left the island.

García repeatedly emphasized Saturday that the risk of community transmission to the general public remains low, warning that unnecessary alarm, misinformation and public confusion run counter to core public health safety principles. By Saturday, security had been visibly tightened across the southern Tenerife industrial port, with Spanish military police and national disaster response teams erecting large purpose-built reception areas and restricting all public access to the waterfront.

Once the MV Hondius is repositioned to its designated anchorage by approximately 07:00 CET (06:00 GMT) Sunday, specialized medical teams will board the vessel to screen every person on board for hantavirus symptoms. As of the latest updates, no additional people have developed active symptoms of the virus, which has an incubation period of up to nine weeks. After screening, passengers and crew will be sorted into groups by nationality and transported to shore in small, controlled shuttles, with pre-arranged charter planes already waiting on the tarmac at Tenerife’s airport to fly them back to their home countries. Medically equipped aircraft are also on standby to airlift any symptomatic people to isolation facilities if needed.

Spanish nationals repatriated from the vessel will be flown directly to Madrid, where they will complete a mandatory quarantine period at the Gomez Ulla military hospital. Officials have not yet confirmed how long quarantine will last for those returning to Spain or other countries around the world, given the pathogen’s unusually long incubation window.

World Health Organization Director-General Tedros Adhanom Ghebreyesus is personally present in Tenerife to oversee the disembarkation operation, and has praised Spanish authorities for their solid, effective response to the outbreak. The outbreak has been traced back to a popular birdwatching landfill site at the southernmost tip of Argentina, where the virus is carried by wild rodents. While human-to-human transmission of this strain is extremely rare, three passengers on the MV Hondius have already died from the infection. Tedros acknowledged that lingering trauma from the COVID-19 pandemic has made local residents’ anxiety legitimate, but reaffirmed that the risk of widespread community contagion is low both due to the inherent nature of the virus and the extensive prevention measures put in place by the Spanish government. He urged nervous local residents to trust the operation’s leadership.

Local medical facilities have also finalized full preparedness for potential complications: dozens of intensive care specialists are on standby at Tenerife’s Candelaria Hospital, with a fully equipped strict isolation bed stocked with testing supplies, a ventilator, and stockpiles of personal protective equipment ready to treat any severely ill patients. “We have never encountered this specific hantavirus strain before, but it is a virus with manageable complications, the same type of cases we handle every day,” said Mar Martin, chief intensive care doctor at the facility. “We are fully trained and absolutely ready.”

When the plan to divert the MV Hondius to Tenerife was first announced, it sparked significant public anger across the island, with port workers holding a noisy protest outside the regional parliament Friday over fears that safety protocols would be insufficient. In recent days, however, greater transparency around the operation has helped restore a cautious calm. In the capital city of Santa Cruz de Tenerife, local resident Jennifer, who was out walking with her child, noted: “The virus is dangerous, of course. But they say you need to have very close contact to get it. If we’re careful, we hope it’s not too serious.”

Some residents remain critical of the central Spanish government’s decision to route the vessel to Tenerife, framing the issue as a political rather than purely medical concern, and a number of locals recalled that early reassurances about COVID-19 preceded uncontrolled pandemic spread. Still, there is no widespread panic on the island. “If they don’t come into contact with us from the ship, then we’re fine,” local resident Esteban told reporters. His partner Isabel added: “If the measures are adequate, then I don’t think people here are worried.”

Not all people on board will disembark in Tenerife: approximately 30 crew members will remain on the MV Hondius to sail the vessel back to its home country of the Netherlands. For the majority of those on board, however, weeks of fear and uncertainty trapped at sea are finally coming to an end — though the next phase of the crisis, a prolonged quarantine period, still lies ahead.

Tensions are running high on the Spanish Canary Island of Tenerife this weekend, as public health authorities and local emergency services finalize strict containment protocols for the imminent arrival of the MV Hondius — a Dutch cruise vessel grappling with a deadly hantavirus outbreak that has already claimed three lives.

As residents voiced deep anxiety, with lingering trauma from the 2020 COVID-19 cruise ship outbreaks still fresh for many, World Health Organization Director-General Tedros Ghebreyesus delivered a direct public message to ease community fears, stressing that this event poses far lower public health risk than the coronavirus pandemic.

“I know you are worried,” Tedros told Tenerife residents in a public address Saturday. “I know that when you hear the word ‘outbreak’ and watch a ship sail toward your shores, memories surface that none of us have fully put to rest. The pain of 2020 is still real, and I do not dismiss it for a single moment. But I need you to hear me clearly: this is not another Covid. The current public health risk from hantavirus remains low.”

Six confirmed cases of hantavirus have been linked to the voyage, which originated in South America. Three passengers have died from the infection to date: the first fatality was recorded on April 11, a second on May 2, and a 69-year-old Dutch passenger who disembarked in St. Helena on April 24 died in South Africa two days later. Two infected British passengers are currently receiving care in the Netherlands and South Africa, while a third Briton is undergoing treatment for a suspected case on the remote Atlantic island of Tristan da Cunha, where the ship made a mid-April stopover.

The MV Hondius is scheduled to dock at Granadilla Port between 4:00 a.m. and 6:00 a.m. GMT Sunday, Spanish Health Minister Mónica García confirmed at a press briefing Saturday. The decision to allow the vessel to dock in Tenerife has been deeply controversial: regional president Fernando Clavijo has openly opposed the move, questioning why the vessel could not complete its outbreak response at its previous stop in Cape Verde. Far-right Spanish party Vox has attacked the national central government over the call, and local protests have broken out across the island in recent days. In contrast, Tedros praised Spanish Prime Minister Pedro Sánchez for the decision, framing it as “an act of solidarity and moral duty,” noting that Tenerife was selected specifically for its robust medical infrastructure, emergency response capacity, and ability to facilitate safe repatriation of passengers.

To eliminate any risk of community spread, Spanish authorities have put in place a rigorous set of containment measures. All passengers will remain quarantined aboard the vessel while initial health screenings are conducted, and no one will be permitted to disembark until a repatriation flight is waiting on the island’s tarmac to carry them directly back to their home countries. Repatriation flights are arranged for passengers from the United Kingdom, United States, France, Germany, Belgium, and Ireland, with Spanish passengers prioritized for disembarkation and repatriation.

All people who interact with passengers during transfer — including bus drivers and logistics staff — will be required to wear FFP2 masks, and passengers will only be permitted to bring a small, sealed bag of essential items such as identification documents, mobile devices and chargers, and basic personal necessities when disembarking. Notably, the body of the passenger who died aboard the vessel will not be unloaded in the Canary Islands; the ship will continue onward to the Netherlands after repatriations are complete, where the remains and personal belongings will be disinfected before being removed.

Health experts explain that hantaviruses are most commonly carried by wild rodents, and the strain detected in this outbreak — the Andes strain — can spread between humans, a mode of transmission that has raised targeted concerns. All infected passengers are believed to have contracted the virus during pre-voyage travel through Argentina, Chile, and Uruguay, where they visited areas with populations of rodent species known to carry the pathogen, Tedros confirmed. As of this publication, the exact origin of the outbreak remains unclear, and public health teams have not yet confirmed whether any additional crew or asymptomatic passengers have been exposed to the virus. A WHO expert is already aboard the vessel to monitor conditions, and Tedros has announced he will travel to Tenerife personally to observe the response operation first-hand. Symptoms of hantavirus infection range from mild flu-like effects including fever, muscle aches, fatigue, and abdominal pain to severe respiratory distress in advanced cases.

A high-profile hantavirus outbreak aboard a South Atlantic cruise ship is sparking widespread criticism of the U.S. Centers for Disease Control and Prevention, with public health experts warning the agency’s absence from the frontline response signals a dangerous erosion of its once-legendary global leadership in infectious disease management.

The outbreak first emerged in early April, when a 70-year-old Dutch passenger developed a fatal febrile illness during a voyage traveling from Argentina to Antarctica. His death was followed by two more fatalities — his wife and a German passenger — and hantavirus was formally confirmed as the causative pathogen on May 2. The World Health Organization formally classified the cluster as an outbreak days later, with roughly two dozen U.S. citizens on board the vessel: seven disembarked last month, while 17 remain on the ship currently docked in the Canary Islands.

Unlike past international public health emergencies, where the CDC stepped in immediately as a core partner to the WHO leading on-site investigations, risk communication and passenger coordination, this outbreak has been almost entirely managed by global health bodies and foreign authorities. Multiple leading public health experts say the CDC’s delayed, low-profile response represents a stark departure from its decades-long reputation as the world’s preeminent public health agency.

“The CDC is not even a player,” stated Lawrence Gostin, a Georgetown University expert in global public health law. “I’ve never seen that before.” Dr. Jeanne Marrazzo, CEO of the Infectious Diseases Society of America, called the outbreak a critical test of U.S. preparedness for emerging biological threats — one the country is failing. “This is a sentinel event that speaks to how well the country is prepared for a disease threat. And right now, I’m very sorry to say that we are not prepared,” she explained.

The muted CDC role comes after 16 months of restructuring under the second Trump administration, which has already withdrawn the U.S. from the World Health Organization, restricted CDC scientists from communicating with international colleagues at multiple points, and cut thousands of roles across the agency — including specialists working in its ship sanitation program. The administration has pivoted away from multilateral global health coordination, instead pursuing a network of one-on-one bilateral public health agreements with individual nations, which it says will advance American innovation in global health. To date, roughly 30 such agreements have been finalized.

HHS Secretary Robert F. Kennedy Jr. has framed current agency reforms as an effort to “restore the CDC’s focus on infectious disease, invest in innovation, and rebuild trust through integrity and transparency.” But experts argue the current hantavirus response exposes the flaws in this new approach.

Jennifer Nuzzo, director of Brown University’s Pandemic Center, noted that hantavirus poses minimal broader risk, as it does not spread easily between humans — the only reason the current situation has not spiraled out of control. Even so, she argues the agency’s response lays bare its weakened current state. “This situation just shows how empty and vapid the CDC is right now,” Nuzzo said.

The CDC has not remained completely silent on the outbreak. Earlier this week, the agency released a brief statement calling the risk to the U.S. general public “extremely low” and framing the U.S. as “the world’s leader in global health security.” Nuzzo pushed back on that messaging, arguing it failed to meet core public health communication standards: “Not only was that not helpful, it actually does damage because a core principle of public health communications is humility.”

Acting CDC Director Dr. Jay Bhattacharya posted on social media that the agency is sharing technical expertise, coordinating with domestic and international stakeholders, and monitoring the health of all U.S. passengers in preparation for medical support. Arizona state officials confirmed this week that one asymptomatic, non-contagious U.S. passenger who disembarked earlier has already returned to the state, with notification coming via the CDC. WHO officials also confirmed the agency has shared basic technical data related to the pathogen.

For the most part, however, federal health officials have declined interview requests and remained tight-lipped, with key updates emerging only through anonymous leaks. It was not until Friday evening that the CDC officially confirmed it would deploy a small response team to the Canary Islands to meet the ship, with a second team prepping at Offutt Air Force Base in Nebraska to receive evacuated U.S. passengers at a dedicated quarantine facility.

Experts have drawn a sharp contrast between this slow response and the CDC’s aggressive action during the 2020 Diamond Princess COVID-19 outbreak, another large cruise ship outbreak off the coast of Japan. At that time, the CDC immediately deployed on-site personnel, led evacuation efforts for U.S. passengers, managed quarantine protocols, shared viral genetic data, coordinated closely with the WHO and Japanese authorities, held regular public briefings, and published rapid research that became the global reference for COVID-19 transmission on cruise ships.

While the overall Diamond Princess response did draw criticism for failing to stop the virus’s global spread, former CDC Director Dr. Tom Frieden and other experts note that the agency was actively engaged from day one. “The CDC was right on top of it, very visible, very active in trying to manage and contain it,” Gostin said, contrasting that with the current delayed, subdued response. He added that the administration’s bilateral approach to global health cannot replace multilateral coordination: “You can’t possibly cover a global health crisis by doing one-on-one deals with countries here and there.”

Tensions are running high on the Spanish island of Tenerife this week as local residents and port workers push back against a national government agreement to allow the hantavirus-exposed cruise vessel MV Hondius to disembark its passengers this weekend. The ship, which departed Cape Verde after three infected people were evacuated and local authorities refused it docking access, is heading for Canary Islands waters after the Spanish administration struck a deal with the World Health Organization (WHO) to accept the passengers. The plan has sparked widespread anger and anxiety across the archipelago, amplifying existing frustrations over ongoing migration pressures.\n\nOn Friday, dozens of port workers gathered outside the Canary Islands regional parliament in Santa Cruz de Tenerife to demonstrate against the docking arrangement. Blowing whistles, sounding vuvuzelas and holding signs highlighting their safety concerns, protesters said they have not been given adequate protection or clear information about the vessel’s arrival. Joana Batista, a representative of the local port workers’ union speaking at the rally, said workers were uncomfortable being assigned to the port without special safety protocols when an infected ship was approaching. Some union members have threatened to block the ship’s access to the island if their demands for full protection and transparency are not met. Batista added that while the ship may be allowed to dock, it must do so with all necessary public health safeguards in place, and local residents deserve full clarity on passenger movement and potential risks to the community.\n\nFor many local residents, the arrival of the cruise ship has compounded long-simmering frustration over the Canary Islands’ status as a primary entry point for thousands of undocumented migrants arriving from North and West Africa. Nutritionist María de la Luz Sedeño, who observed the protest, called the ship’s planned arrival the “last straw” for local residents tired of bearing the brunt of unaddressed international crises. While some Canary islanders take pride in welcoming migrant arrivals, others share Sedeño’s frustration, and the crisis has become a unifying point of discontent for many who feel the national government ignores local input. According to NGO Caminando Fronteras, more than 3,000 people died attempting to reach the Canary Islands in 2025, most traveling in unsafe makeshift dinghies. The ongoing migration situation will draw global attention next month when Pope Leo is scheduled to visit the islands to meet with migrants and aid organizations. Sedeño also criticized the central government for overriding clear opposition to the cruise ship’s arrival from Canary Islands regional president Fernando Clavijo, saying “the people here are not being listened to.”\n\nIn response to accusations of overreach and lack of transparency, the Socialist-led national government has released full details of its public health plan for the vessel’s arrival. Instead of docking directly at a populated Tenerife port, the MV Hondius will anchor offshore, and passengers will be transported via ferry to the remote Granadilla industrial port in the island’s southeast, far from residential neighborhoods. After disembarkation, all foreign passengers will be immediately repatriated, while the 14 Spanish nationals on board will be transferred to Madrid for quarantine. Virginia Barcones, head of Spain’s civil protection agency, emphasized that authorities have taken all steps to ensure no contact between passengers and local residents, guaranteeing that local communities will be “absolutely and completely protected.”\n\nThe government’s detailed plan has eased concerns for some Tenerife residents. Marialaina Retina Fernández, a local pensioner, said she feels calmer now that clear information has been released. Noting that the Canary Islands have access to high-quality local healthcare, she expressed cautious acceptance of the temporary presence of the ship’s passengers. “It’s not ideal that they all end up coming here, but if the authorities say they’ll do everything possible to make sure nobody gets infected, let’s hope that’s how it is,” she said.\n\nDespite the government’s public health safeguards, far-right party Vox has sought to politicalize the issue by drawing parallels between the cruise ship arrival and undocumented migrant arrivals. Meanwhile, many local residents say the arrival of a multi-national ship with a viral outbreak brings unwanted flashbacks to the early days of the COVID-19 pandemic, when the first confirmed COVID case in Spain was a German tourist on nearby La Gomera, followed by the quarantine of 1,000 hotel guests and staff on Tenerife. Both the WHO and the Spanish government have explicitly pushed back on comparisons to the COVID-19 pandemic, downplaying the epidemiological risks of the current hantavirus situation. Still, many residents remain on edge. Retina Fernández, for her part, framed the situation as just another crisis the Canary Islands have been forced to manage, noting “we’re used to all sorts of problems arriving here, and you can see that we’re good at managing these situations.”

As the cruise ship MV Hondius, hit by an outbreak of hantavirus, steams toward the Spanish port of Tenerife in the Canary Islands, a surprising tension has emerged among its 140+ passengers and crew. For the Spanish nationals on board, anxiety stems not from the risk of contracting the virus itself, but from the hostile public reception they expect to face once they set foot on land. In exclusive phone interviews with the Associated Press on Friday, two anonymous Spanish passengers — a man and a woman — detailed the vitriol and misinformation spreading across public platforms about the ship and those aboard.

Sensationalized mainstream coverage and inflammatory social media content, including memes calling for the vessel to be sunk, have painted passengers as dangerous viral vectors to be shunned. “You go onto social media – they want to dynamite the boat. They want to sink the boat,” the male passenger told AP. “You see what’s out there and you realize you’re heading into the eye of a hurricane,” the female passenger added. “Many people forget that in here there are more than 140 passengers. In reality, there are 140 human beings.” Both requested anonymity out of fear of further backlash once they disembark, currently scheduled as early as Sunday.

This wave of public panic has echoes of the early days of the COVID-19 pandemic, when viral outbreaks on cruise ships sparked global alarm. But World Health Organization officials have repeatedly pushed back against misplaced comparisons, stressing that hantavirus poses minimal risk to the general public and this event is not the start of a new global pandemic. “This is very different virus. I want to be unequivocal here,” stated Maria Van Kerkhove, WHO’s head of epidemic and pandemic preparedness, on Thursday. “This is not the start of a COVID pandemic.”

Unlike SARS-CoV-2, which spreads easily between people, hantavirus is most commonly transmitted to humans through inhalation of particles contaminated by rodent droppings. While the Andes strain detected on the MV Hondius can spread between people in extremely rare cases, the overall risk of widespread transmission remains very low. Despite these clear expert assurances, misinformation and distrust in public health guidance — a trend that took hold during the COVID pandemic — have persisted. A Spanish anti-establishment group called Iustitia Europa, which gained prominence opposing COVID-19 public health restrictions, has publicly called for the MV Hondius to be barred from entering Spanish territorial waters. “The Canary Islands cannot become Europe’s health laboratory … We demand transparency, responsibility, and protection for Spaniards to avoid repeating the mistakes of the past,” the group posted on social media platform X.

Even some regional Spanish politicians have echoed public anxiety, taking a hard defensive stance against the ship’s arrival. Canary Islands regional president Fernando Clavijo told Spanish newspaper El País on Friday that he would not feel at ease until the ship departs Spanish waters and all passengers have reached their designated quarantine sites. Madrid regional leader Isabel Díaz Ayuso also publicly opposed the decision to transfer 12 Spanish passengers from the ship to a Madrid military hospital for quarantine, as planned by national authorities.

“The public narrative has painted this as a boat of infected people, a boat of multimillionaires, full of rats,” the male passenger on board explained. “Society is in some way contaminated with a lot of noise and a lot of lies.” He did note that he has found some comfort in the Spanish government’s promise of official escorts upon arrival in Tenerife, where port workers held a protest this week over a lack of transparency regarding planned safety protocols. Spanish authorities have clarified that the escorts are standard protocol to maintain isolation requirements, not a measure to protect passengers from violent confrontation.

Contrary to chaotic public portrayals of life on board, daily routines on the MV Hondius have remained calm in the days approaching port. After a team of epidemiologists boarded the ship off the coast of Cape Verde to brief passengers on the actual risks of the outbreak, most have been reassured that human-to-human transmission is extremely rare. Passengers who leave their cabins for common areas follow masking and social distancing rules, spending time reading, attending educational talks, joining early morning exercise groups on the upper decks, or birdwatching — a key activity for many travelers who had embarked on the voyage to photograph wildlife in remote Atlantic regions, not to become the center of a global public health story.

Remarkably, despite the stigma and uncertainty they now face, both Spanish passengers say the experience would not stop them from taking another cruise in the future. “For me, personally, traveling is a means to … live out what I’m passionate about — which is observing nature and documenting nature,” the female passenger said. “Of course I would go on a cruise again.”

In an unfolding global public health incident, a cruise ship carrying 140 passengers and crew members, already struck by a deadly hantavirus outbreak, is nearing its scheduled arrival at the Spanish island of Tenerife in the Canary Islands early Sunday, prompting coordinated international response preparations. As of current reports, at least three passengers have already succumbed to the virus, with multiple additional people confirmed infected, leaving public health agencies across multiple nations racing to address gaps in critical information about the incident.\n\nHantavirus, a pathogen most commonly transmitted to humans through inhalation of air contaminated with rodent droppings, typically presents symptoms between one and eight weeks after initial exposure. The World Health Organization has assessed that the overall risk of widespread community transmission from this outbreak remains low, but the specific Andes variant linked to the cruise ship cases carries a rare but documented potential for human-to-human spread, raising additional safety concerns.\n\nDespite incremental updates from local authorities and the vessel’s operator, Netherlands-based Oceanwide Expeditions, several core questions about the outbreak remain unanswered, slowing coordinated containment efforts.\n\nFirst, the origin of the outbreak has not been definitively confirmed. Argentine investigators have put forward a preliminary hypothesis that an infected Dutch couple may have contracted the virus during a bird-watching excursion prior to boarding the MV Hondius in Ushuaia, Argentina’s southernmost town, on April 1. Argentina’s Ministry of Health has centered its traceback investigation on Ushuaia, and announced plans to deploy investigative teams to the region in the coming days — though the statement provided to the Associated Press gave no explanation for the planned delay in the team’s arrival. No official body has yet verified where or how the index case acquired the virus.\n\nSecond, the full timeline for what happens next for the remaining passengers and crew on board remains unclear. Spanish emergency authorities are currently on standby to receive the vessel in Tenerife, and confirmed Friday that disembarkation will only proceed once repatriation flights for all people on board are fully arranged, with passengers evacuated via small boats to dedicated buses waiting to transport them directly to airports. The U.S. and U.K. governments have already confirmed they will send dedicated aircraft to retrieve their respective citizens from the Canary Islands, but most other nations have not publicly released their repatriation plans, leaving it unknown how long the remaining people on the ship will need to wait before they can leave. Virginia Barcones, head of Spain’s national emergency services, added that Spanish officials have requested medically equipped aircraft to transport symptomatic passengers, but it remains unconfirmed whether these specialized planes will be available in time.\n\nThird, the full scope of potential exposure remains unaccounted for, with conflicting data sowing confusion. According to Oceanwide Expeditions, the MV Hondius departed Ushuaia on April 1, made two intermediate stops before the outbreak was declared. Six additional passengers boarded at the remote South Atlantic island of Tristan da Cunha, after which the ship stopped at St. Helena, where 30 passengers disembarked — including a Dutch woman and the body of her husband, who had died from the virus on board. The operator says two of those 30 disembarked passengers are believed to be Chileans who boarded at Tristan da Cunha, but their nationalities have not been definitively confirmed. On Friday, a U.K. overseas territories government official confirmed that a Tristan da Cunha resident has been hospitalized with suspected hantavirus symptoms, but it remains unclear whether this person had any contact with the cruise ship. Initial passenger counts provided by the operator were inconsistent: the company first reported 114 passengers departed Argentina with an unlisted number of crew, before updating figures to confirm 61 crew from 12 countries on board, with no clarity on whether any crew changes occurred during the voyage. The operator was forced to correct passenger and nationality counts for those who disembarked at St. Helena after discovering errors in initial reporting, and the final total of people potentially exposed still differs from the estimate provided by the Dutch Foreign Ministry, with no explanation for the discrepancy.\n\nFourth, the full whereabouts of all disembarked passengers and the extent of their potential contacts remain unknown. Many of the passengers who got off at St. Helena continued onward travel to other countries. The Dutch woman whose husband died on board flew to Johannesburg, South Africa, before boarding a flight bound for Amsterdam; she was removed from the flight due to severe illness and later died. Public health officials in South Africa and the Netherlands are currently working to trace every individual who came into contact with the woman during her travels. One flight attendant who developed symptoms after interacting with the woman has already tested negative for hantavirus. Some national governments, including the U.K., have confirmed the locations of their citizens who disembarked early: British health officials say two are self-isolating at home, four remain on St. Helena, and one has been located outside of the U.K. Even so, officials have not disclosed how many additional people these citizens may have been in contact with since leaving the ship, leaving open the possibility of unmonitored exposure.
