France Quarantines Five MV Hondius Passengers After Hantavirus Symptom Case

France placed five MV Hondius passengers in strict isolation in Paris after one of the evacuees, a French national, developed symptoms on a chartered flight from Tenerife. The plane landed in the capital and was met by emergency vehicles, a visible sign of how seriously officials treated a case linked to the rare hantavirus outbreak aboard the cruise ship.

Prime Minister Sébastien Lecornu said the five would remain quarantined in Paris until further notice. The isolation was meant to separate close contacts quickly, not to imply that every symptomatic traveler was confirmed ill. In outbreaks like this, symptoms after repatriation can signal exposure that still needs testing and monitoring, which is why health authorities are treating the flight as a containment event rather than waiting for a diagnosis to settle the question.

The MV Hondius evacuation began Sunday off Tenerife in Spain’s Canary Islands and was expected to continue through Monday. Spanish passengers were the first to disembark and were flown to Madrid for admission to a military hospital. The ship, a Dutch-flagged vessel operated by Oceanwide Expeditions, had left Ushuaia, Argentina, on April 1 with 88 passengers and 59 crew members from 23 nationalities, according to the World Health Organization.

By May 4, the World Health Organization said seven cases had been identified among the 147 passengers and crew, including two lab-confirmed hantavirus cases, five suspected cases, three deaths, one critically ill patient and three people with mild symptoms. The agency said illness onset ranged from April 6 to April 28, with fever, gastrointestinal symptoms, rapid progression to pneumonia, acute respiratory distress syndrome and shock. Health officials have emphasized that the public health risk remains low and that this outbreak is not the start of another COVID pandemic.

The virus involved has been identified as the Andes strain of hantavirus, the only known subtype that can spread person-to-person. That detail explains why contact tracing has stretched beyond the ship itself: French health authorities had already been monitoring a separate French contact case who was on the same plane as another cruise-ship patient before that patient was hospitalized. The U.S. Centers for Disease Control and Prevention has also said it was coordinating a response for American travelers aboard the ship with confirmed hantavirus.

As the evacuation continued and hospitals received passengers in Paris and Madrid, officials were balancing two realities at once: the outbreak is serious for those exposed, but the broader public risk remains limited when contacts are isolated quickly and monitored closely.
