A French woman is currently receiving supportive care at Hôpital Bichat-Claude-Bernard in Paris after being evacuated from a cruise ship in the Canary Islands due to hantavirus infection. This outbreak has raised alarm as hantavirus can be deadly, particularly the Andes strain, which is capable of limited person-to-person transmission. The woman, one of five French nationals aboard the MV Hondius, is in the 'final stage of supportive care,' which includes the use of extracorporeal membrane oxygenation (ECMO) to assist her breathing. Health experts emphasize that hantavirus is primarily transmitted from rodents to humans through inhalation of particles from rodent droppings, urine, or saliva. While most strains do not spread efficiently among humans, the Andes strain has been linked to documented cases of human transmission. The fatality rate for hantavirus can be as high as 35% in the U.S., and even higher for some strains, making early diagnosis and intensive care critical for improving survival odds. Currently, there is no vaccine or specific antiviral treatment available, and care is largely supportive. Health authorities are urging anyone who had close contact with confirmed cases to monitor their health closely and seek medical attention if symptoms arise.
