A medical crisis aboard the expedition cruise ship MV Hondius has left three people dead and sparked widespread alarm as passengers face quarantine in the middle of the Atlantic. The vessel, which remained anchored off Cape Verde for several days, has become a focal point of concern following an outbreak of the hantavirus.
Health officials have identified the specific strain as the Andes variant. This particular version of the virus is notable for being the only hantavirus species capable of limited human-to-human transmission, particularly among those in close and prolonged contact.
Evacuations and Medical Emergencies
The emergency response has involved complex international medical transports. On May 6, 2026, a 65-year-old German woman was flown to Europe via a special aircraft after having close contact with a deceased fellow citizen. She was admitted to the University Hospital Düsseldorf for precautionary medical clarification, though the clinic noted she was a contact person without a confirmed infection.
Two crew members—a 56-year-old British man and a 41-year-old Dutch man—were also evacuated for urgent medical care. One transport aircraft was forced to make an unplanned stop in Gran Canaria due to a defect in an isolation capsule.
Since May 10, the process of evacuating passengers from the MV Hondius has continued. To date, there are six additional confirmed cases of the virus and two suspected cases. Separately, Switzerland has reported one case of hantavirus on land.
Assessing the Pandemic Risk
The imagery of 150 people in quarantine has drawn comparisons to the early days of the COVID-19 pandemic. However, virologist Jonas Schmidt-Chanasit suggests such a comparison is inappropriate. While he describes the situation on the MV Hondius as “unusual” and something that “must be taken very seriously,” he believes a scenario similar to SARS-CoV-2 is “very unlikely.”
Schmidt-Chanasit explains that the primary difference lies in transmissibility. While SARS-CoV-2 spread efficiently through the respiratory tract—even via asymptomatic individuals—the Andes virus does not behave this way. He notes that the virus is dangerous because of the severity of the illness it causes, rather than its ability to spread easily through the general population.
Current Status and Next Steps
Several German passengers have already been transported to Germany, arriving in Frankfurt for examination and further distribution. Another German national is currently in Great Britain.
The remaining passengers are scheduled to travel to Tenerife. Once the passengers have been disembarked, the MV Hondius is expected to sail toward Rotterdam with a portion of its crew. The body of the deceased German passenger will remain on the ship until it reaches its destination.
Medical experts emphasize that the most critical steps moving forward may include the continued isolation of the sick, rigorous contact tracing, and strict medical monitoring to keep the number of infections low.
Frequently Asked Questions
Is there a vaccine for the Andes virus? No, there is currently no vaccine or direct therapy available to treat the virus. How is the Andes virus different from other hantaviruses? The Andes variant is the only type of hantavirus that can be transmitted from one human to another, specifically through close and long-term contact. Is the general public at risk from this outbreak? According to virologist Jonas Schmidt-Chanasit, the risk is relevant for those who had close contact on board the ship, but not for the general population.
Do you think current international maritime laws are sufficient to handle sudden viral outbreaks on expedition cruises?
