The MV Hondius, a Dutch-flagged luxury expedition cruise ship, arrived at the port of Granadilla in Tenerife on May 10 carrying the remnants of a hantavirus outbreak that has killed three people and infected at least six.

The evacuation is now underway. According to CNBC, Spanish Health Minister Mónica García confirmed passengers are being sorted by nationality, bused to Tenerife airport in military vehicles, and flown home on government charter planes. Spanish and French nationals departed first. The Netherlands, Canada, UK, Turkey, Ireland, and the United States followed. Australia's flight — carrying New Zealand citizens and others — was expected Monday.

Americans returning home aren't just going back to their couches. According to the Washington Post, U.S. passengers are being quarantined in Nebraska. The CDC has activated a Level 3 hantavirus response, according to Fox News.

The timeline of the outbreak

The first passenger died more than three weeks before anyone knew what this was. According to CNBC, hantavirus was NOT detected until May 2 — 21 days after that first death — when South African health officials tested a British man who was in intensive care. A person died on a ship, then two more followed, and it took three weeks to identify the pathogen.

Two of the three confirmed dead are a Dutch couple. The third is a German national, according to CNBC. Eight people total who had been on the ship have now fallen ill, six confirmed with hantavirus, according to WHO Director-General Tedros Adhanom Ghebreyesus, who traveled to Tenerife himself to oversee the evacuation.

The Andes strain

Hantavirus is normally a rodent-to-human disease. You breathe in contaminated dust from infected rodent droppings. It does NOT typically spread person-to-person. Most coverage has mentioned this reassuring fact prominently.

The specific strain identified on the MV Hondius is the Andes strain. According to BBC News, the Andes strain DOES transmit between humans — making it the exception to the rule that health officials keep citing. That distinction becomes significant when you have 147 people locked on a ship together for weeks.

The WHO said the first case was likely infected before boarding — possibly during travel in Argentina or Chile, where Andes hantavirus is endemic — with spread then occurring on the ship, according to CNBC. No rodents were detected on the vessel.

The remote island case

One passenger disembarked the MV Hondius on April 14 at Tristan da Cunha — a British overseas territory in the South Atlantic with a population of 221 people and NO airstrip. According to BBC News, that man reported diarrhea on April 28 and fever on April 30. His condition is described as stable, and he is isolating.

The British Army's response: parachute in. According to BBC News, six paratroopers and two medical clinic personnel were dropped onto the island from an RAF A400M aircraft, along with oxygen supplies that the Ministry of Defence described as being at a "critical level." This is an extraordinary logistical response to a single suspected case on one of the most isolated inhabited places on Earth.

Tracking dispersed passengers

Fox News reported that officials were scrambling to locate approximately 40 passengers who had already disembarked before the outbreak was identified. The WHO has now recommended a 42-day quarantine for all 147 passengers and crew from Sunday's date of evacuation, according to CNBC.

Six U.S. states are actively monitoring returning passengers: Arizona, California, Georgia, Texas, Virginia, and New Jersey, according to a former CDC official cited by CNBC. Health departments in Arizona, Georgia, and Texas confirmed those passengers have shown no symptoms so far.

Assessing the risk

Prediction market platform Kalshi put the odds of WHO declaring hantavirus a "public health emergency of international concern" in 2026 at just 21%, according to CNBC. Trading volume on that contract hit $174,000 — high for a new market, suggesting real interest, but the odds remain low.

WHO's Tedros told media: "While this is a serious incident, WHO assesses the public health risk as low. It's possible that more cases may be reported."

Health officials are right to downplay pandemic risk based on available data. This is NOT COVID. But three people are dead from a pathogen that took 21 days to identify, on a ship that has now scattered passengers to a dozen countries, with one case sitting on an island that required a military parachute drop to reach.

The cruise industry outlook

According to CNBC, the global cruise industry served a record 37.2 million passengers in 2025, up 7.5% from 2024. Expedition cruising — the high-end segment that takes wealthy travelers to Antarctica, the Arctic, and remote Atlantic islands — is booming. Luxury travel company Travelopod's founder Ritu Panesar told CNBC her clients routinely spend $30,000 to $50,000 per person on these itineraries. Interest in Antarctica trips was up 34% year-over-year through April 2026, according to travel insurance marketplace Squaremouth's chief marketing officer Jacqueline Mondelli.

Travel experts told CNBC the outbreak is unlikely to dent demand. But those same experts might want to ask: when you're three days from the nearest airstrip on a ship with no quarantine infrastructure, what exactly is the evacuation plan if something goes wrong?

Three families now know the answer to that question.
