Hantavirus Outbreak Grows to 11 Cases as Critically Ill French Patient Fights for Life
A French woman infected in the cruise ship hantavirus outbreak is on life support in Paris as the total case count climbs to 11, with WHO urging caution.
French Hantavirus Patient on Life Support as Case Count Climbs
A French woman who contracted hantavirus during a deadly outbreak aboard a cruise ship is fighting for her life at a Paris hospital, where doctors have placed her on an artificial lung support system. The total number of reported cases linked to the outbreak has now risen to 11, with 9 officially confirmed.
Severe Condition Prompts Extreme Medical Intervention
Dr. Xavier Lescure, an infectious disease specialist at Bichat Hospital in Paris, described the woman's condition as grave. The infection has triggered life-threatening damage to both her lungs and heart, forcing medical staff to connect her to an extracorporeal membrane oxygenation (ECMO) device — a machine that circulates blood through an artificial lung, enriches it with oxygen, and returns it to the body.
Dr. Lescure described the intervention as "the final stage of supportive care," noting that the goal is to take enough strain off the vital organs to allow them time to heal.
WHO Monitors Situation Closely
The World Health Organization's Director General, Tedros Adhanom Ghebreyesus, addressed the outbreak on Tuesday, offering cautious reassurance while warning that vigilance remains essential.
"At the moment, there is no sign that we are seeing the start of a larger outbreak," Tedros said. However, he added that the situation could shift, noting the virus carries a long incubation period — potentially up to eight weeks — meaning additional cases could still emerge in the weeks ahead.
Tedros confirmed that all known cases so far have been traced exclusively to passengers or crew aboard the affected vessel, with no evidence of broader community transmission.
New Case Confirmed in Spain
Spain's health ministry reported Tuesday that a Spanish passenger who was evacuated from the ship has tested positive for hantavirus. The individual is currently in quarantine at a military hospital in Madrid, marking the latest addition to the growing case list.
The Cruise Ship Outbreak: What We Know
Health authorities have identified this as the first known hantavirus outbreak to originate on a cruise ship. The MV Hondius, operated by Oceanwide Expeditions, has since completed the evacuation of all passengers and most crew members and is now en route to Rotterdam in the Netherlands for a thorough cleaning and disinfection.
A total of 87 passengers and 35 crew members were escorted off the vessel at Tenerife by personnel wearing full-body protective equipment and respiratory masks. The carefully coordinated evacuation concluded on Monday night. Two chartered aircraft subsequently landed in the Dutch city of Eindhoven carrying Dutch nationals, passengers from Australia and New Zealand, and Filipino crew members — all of whom were immediately placed into quarantine.
Three Deaths Linked to Outbreak
Three people have died as a result of the outbreak, including a Dutch couple whom the WHO believes were among the first passengers exposed to the virus. The couple had spent several months traveling through Argentina and neighboring South American countries before boarding the cruise ship.
Argentine officials have suggested the pair may have been infected during a bird-watching excursion that included a visit to a landfill site, where rodents known to carry the virus are commonly found. Argentina's health ministry announced Tuesday that a team of scientific experts will be deployed in the coming days to investigate the site and other locations the couple visited. However, local authorities in the departure province have pushed back on the theory that the outbreak originated there.
Hantavirus: Key Facts and Transmission Risks
Hantavirus typically spreads through contact with infected rodent droppings, urine, or saliva and is not easily passed from person to person. However, the specific strain identified in this outbreak — the Andes virus — is considered unusual in that it may be capable of human-to-human transmission in rare circumstances.
Common symptoms include fever, chills, and muscle aches, typically appearing anywhere from one to eight weeks following exposure. There is currently no approved cure or vaccine for hantavirus, although the WHO emphasizes that early detection and prompt medical treatment can significantly improve a patient's chances of survival.
Quarantine Protocols and Hospital Breach
WHO chief Tedros has recommended that all returning passengers observe a 42-day quarantine period, either at home or in a designated facility. He acknowledged that the WHO cannot enforce compliance and that individual countries may adopt varying approaches to monitoring passengers who are not showing symptoms.
A separate concern emerged Monday when Radboud University Medical Center in Nijmegen, the Netherlands, revealed that 12 hospital employees had been placed into a six-week precautionary quarantine. The staff members were exposed to bodily fluids from a hantavirus-positive patient who had arrived via one of the evacuation flights, and the hospital acknowledged the fluids were not handled according to the required safety protocols. While the facility assessed the risk of infection as low, it initiated the quarantine as a precautionary measure.
