Topline
Passengers on the hantavirus-stricken MV Hondius cruise ship will soon be evacuated in an operation that will be directly observed by the Tedros Adhanom Ghebreyesus, the World Health Organization’s director-general, who said Saturday the people would be taken back to their respective countries under strict monitoring.
Timeline
Ghebreyesus issued a lengthy statement to the Spanish island of Tenerife on Saturday, saying he will travel to the island to watch the tightly monitored operation to transport passengers of the Hondius, who remain asymptomatic, back to their respective countries.
Passengers will be transported to the island’s airport in sealed and guarded vehicles, Ghebreyesus said (read here for further details on the evacuation process).
ABC News cited an unnamed official from the Canarias Region government of Spain who said passengers will wear full protective equipment and that those who are not ready to be taken to an airplane of their destination will remain on the ship.
Fourteen passengers from Spain will be the first to be transferred.
Unnamed sources told CBS News on Friday evening that the Centers for Disease Control and Prevention activated a level three emergency response for the hantavirus ship outbreak, the agency’s lowest level of emergency response that involves the activation of disease experts, their staff and potential involvement from staff at the CDC’s Emergency Activation Center.
CNN cites unnamed health officials in reporting the estimated 17 Americans onboard the cruise ship will be escorted on a charter flight and taken to the National Quarantine Unit, a federally funded quarantine facility in Omaha. Forbes has reached out to the Centers for Disease Control and Prevention for more information.
New Jersey Gov. Mikie Sherrill says two state residents are being monitored after they were potentially exposed to a cruise passenger with hantavirus after that person disembarked the ship, joining local health officials in California, Arizona, Georgia, Texas and Virginia in monitoring potential contacts.
Spanish health official Javier Padilla says a 32-year-old woman in the southeastern Spanish province of Alicante (who shared an airplane with a MV Hondius cruise ship passenger confirmed to have hantavirus) is now showing symptoms consistent with the disease, bringing the total number of confirmed and suspected cases to nine (see map below).
Two residents of Singapore who were onboard the cruise ship during the outbreak and were on the same flight as the patient who later died have tested negative for the virus, Singaporean officials say.
Canary Islands President Fernando Clavijo says the MV Hondius will not be allowed to dock when it arrives in Tenerife on Saturday and will instead anchor off shore, where passengers will be taken to land via small boat only when their evacuation plane is already on the tarmac. Nobody still on the ship is showing symptoms as of Friday, per WHO officials.
U.K. health authorities identify a new suspected case of hantavirus linked to the cruise ship outbreak—a British man on the remote South Atlantic island Tristan da Cunha.

Oceanwide Expeditions, operator of the cruise ship MV Hondius, says at least 29 living passengers from 12 countries disembarked the ship and went home after the death of the first passenger on board (before officials knew of the outbreak). Those countries are Canada, Denmark, Germany, Netherlands, New Zealand, Switzerland, Sweden, Singapore, Saint Kitts and Nevis, Turkey, United Kingdom and the United States.
Dr. Tedros Ghebreyesus, director of WHO, says some of those passengers shared an airplane to Johannesburg with a woman from the ship who later died.
Ghebreyesus says none of the remaining passengers or crew aboard the MV Hondius are symptomatic, but that “it is possible more cases will be reported” because it can be up to six weeks before those infected with the Andes variant of hantavirus show symptoms. He insisted the public health risk remains “low.”

Where Is The Mv Hondius?
As of Friday morning, the ship is off the coast of Morocco cruising en route to the Canary Islands. Passengers are isolating in their cabins and teams of doctors, surgeons, nurses and laboratory specialists in protective gear are aboard the ship.
Big Number
Almost 150. That’s how many people are stuck onboard the Mv Hondius. That total counts people from across 23 countries, including 17 Americans.
Who Are The Hantavirus Patients?
- Suspected case: A 70-year-old Dutch man died aboard the MV Hondius on April 11. Because hantavirus was not suspected at the time of his death, no test samples were taken, but he is now believed to be the first hantavirus case on the ship.
- Confirmed case: The man’s 69-year-old wife died shortly after departing the ship with his body. Her blood later tested positive for the Andes strain of hantavirus.
- Suspected case: A German woman died aboard the ship on May 2. Her body is still on board and has not yet been tested for the disease, but officials suspect she died of hantavirus.
- Confirmed case: A British expedition guide was medically evacuated to South Africa after presenting to the ship’s doctor with symptoms. He remains in critical condition, though health officials say he is improving, and tests confirmed he had contracted the Andes virus.
- Confirmed case: A Dutch passenger was evacuated from the ship Wednesday and flown to the Netherlands to receive medical care.
- Confirmed case: A British passenger was evacuated from the ship Wednesday and flown to the Netherlands to receive medical care.

- Tested negative: A KLM flight attendant who contracted symptoms after a brief interaction with the now-deceased Dutch woman tested negative for hantavirus, officials said Friday.
What Happens To People Who May Have Been Explosed To Andes Hantavirus?
WHO Technical Officer Anaïs Legand explained Friday that officials are looking to find anyone who may have come in contact with an infected person, and will assess their level of exposure. Each person will then be given a level of risk, and a corresponding action plan, which will include a daily temperature check for 42 days and a daily assessment for any signs of feeling sick. From there it varies by country and level of risk, Legand said, but the WHO recommends a daily check in with a medical professional, either in person, by phone or through an app.
Key Background
The MV Hondius left Ushuaia, Argentina on April 1 for the Canary Islands off the coast of northwestern Africa, visiting some of the world’s most remote islands along the way. The ship made stops in Antarctica, South Georgia, Nightingale Island, Tristan da Cunha, St. Helena (where the Dutch man’s body was taken from the ship) and Ascension Island, where the British man was medically evacuated. The ship then sailed for the port of Praia in Cape Verde, but was denied permission to dock. Despite protests from the president of the Canary Islands, Spanish officials later said the ship would be allowed to dock in Tenerife, where passengers can disembark and return to their home countries.
Tangent
A passenger who was aboard the MV Hondius before disembarking several weeks into the journey told the BBC the operator of the cruise ship “didn’t inform us about any potential viruses” after the death of the ship’s first passenger amid the outbreak. Ruhi Cenet, a Turkish Youtuber, told the agency he is “very unhappy” with how the outbreak was handled and that despite being onboard for almost two weeks after the man’s death, passengers were told the man was “not infections” and, therefore, the remaining passengers took no health and safety precautions. “We were together in the lecture rooms. We were all together during breakfast, lunch and dinner. I’m talking about over 100 passengers. People were socializing, they were sitting side by side,” Cenet said of life onboard ship. The ship’s operator has said it could not have informed passengers of the disease any sooner because they did not know what killed him and believed his death to be an isolated incident.
What Is The Andes Hantavirus?
Andes is the only hantavirus strain known to be transmitted person to person. People typically get hantavirus from contact with rodents like rats and mice—normally when exposed to their urine, droppings and saliva, or sometimes through a bite or scratch—but officials say no rodents have been found on the MV Hondius ship. Andes is found in South America, specifically Argentina and Chile, and person-to-person transmission has been associated only with close and prolonged contact during the early phase of illness, when the virus is more transmissible. The U.S. Centers for Disease Control and Prevention says symptoms of hantavirus usually emerge within a week or two, but can take up to eight weeks in some cases. The agency insists there is a “low” risk to the wider population and agency information shows transmission of the Andes virus is very low when appropriate infection prevention and control measures are taken.
What Are The Symptoms Of Hantavirus?
Hantaviruses cause two syndromes: hantavirus pulmonary syndrome, mostly found in the Western Hemisphere, and hemorrhagic fever with renal syndrome, found mostly in Europe and Asia. Hantavirus pulmonary syndrome causes fatigue, fever, muscle aches, abdominal problems, headaches, chills and dizziness in the early stages, and late symptoms include chest tightness, coughing, shortness of breath and lungs filling with fluid. Of those who develop respiratory symptoms, the mortality rate is 38%. Hemorrhagic fever with renal syndrome affects the kidneys and causes a wide range of symptoms, including blurred vision, low blood pressure, acute shock, internal bleeding and kidney failure. The severity of the disease varies on the strain of hantavirus, and mortality rates range from less than 1% to 15%.
How Is Hantavirus Treated?
There is no specific treatment for hantavirus infections and patients usually receive supportive care like supplemental oxygen for respiratory issues and dialysis in the case of kidney failure. Despite a viral online claim, scientists and doctors have repeatedly said the anti-parasitic drug ivermectin is not a proven treatment.
Surprising Fact
Betsy Arakawa, the wife of actor Gene Hackman, died in February 2025 from hantavirus pulmonary syndrome. She was 65.
