Hantavirus on Cruise Ship MV Hondius: What We Know About the Outbreak

Spring 2026 shocked the world with news of a hantavirus outbreak on a cruise ship. The MV Hondius with 150 passengers was heading from Antarctica. People started getting sick on board. Three died. This is the first mass infection case outside South America.
It all began when the ship left Ushuaia, Argentina. Several days after departure, passengers felt unwell. Symptoms resembled severe cold. But condition rapidly worsened.
Who became the infection source — couldn't be established. Presumably, infection happened before boarding. A Dutch couple — likely "zero" patients. They went on a birdwatching excursion. Visited an Argentine landfill. That's where they apparently caught the virus.
Andes Strain — the Most Dangerous
The virus that struck passengers is the Andes strain. It's the only hantavirus that transmits from person to person. This property makes it especially dangerous.
For comparison: in Russia and Europe, hantaviruses almost don't transmit from person to person. Andes strain is the exception. That's why WHO raised the alarm.
| Indicator | Value |
|---|---|
| Infected on board | 7 people |
| Died | 3 people |
| Mortality | About 43% |
| Strain | Andes virus |
| Human transmission | Yes, with prolonged contact |
Mortality turned out to be high. Three of seven infected died. For comparison: with ordinary HFRS form in Russia, lethality is about 0.3%.
How Events Developed
First symptoms appeared in an elderly couple from the Netherlands. The man felt bad several days after boarding. Temperature rose. Fever started. Condition rapidly worsened.
The man died on board. His wife died later — in an Amsterdam hospital after evacuation. The third victim was an elderly woman from Germany.
Other infected were hospitalized. Some were in intensive care units. Several developed hantavirus pulmonary syndrome.
Evacuation and Quarantine
The ship couldn't dock anywhere for several days. Spain, Morocco, Portugal — all refused. Finally, Canary Islands agreed to accept the liner.
Passengers were evacuated by special flights. Americans were sent to the National Quarantine Center in Nebraska. Britons were asked to self-isolate for 45 days. Spaniards were placed in a military hospital.
WHO Director-General Tedros Ghebreyesus personally flew to Tenerife. Watched the evacuation. Assured the public: risk for others is extremely low. The virus doesn't transmit by airborne droplets.
Is This Virus Dangerous for Others
Doctors reassure: this won't become a new pandemic. Main difference from COVID-19 — transmission method.
Hantavirus doesn't fly through the air. You can only get infected with prolonged contact with a sick person. Or with contact with rodents. Ordinary masks aren't needed.
Nevertheless, authorities warn: Andes strain is dangerous. If it mutates and gains ability to transmit by airborne droplets — then catastrophe begins. So far this hasn't happened.
After the incident, monitoring is enhanced. Track passengers of all flights who could have contacted the sick. In several countries, new infection cases were identified.
What This Means for Travelers
If you plan cruises in South America — be careful. Avoid places with many rodents. Don't visit landfills and abandoned buildings.
If temperature rises after the trip — see a doctor immediately. Tell about the route. This will help diagnose quickly.
Otherwise — panic isn't needed. Chance of infection is extremely low. Especially in Russia, where different strains circulate.
