A case of hantavirus, which recently sparked international alarm, has been detected in a Franco-Argentine national who holidayed in France in July before being put in isolation in Spain, the French health ministry said Thursday. The authorities have not indicated a link to a deadly outbreak of Andes strain hantavirus on a cruise ship earlier this year that triggered a global health alert. A French woman who contracted the virus on the MV Hondius was discharged from intensive care on Thursday after nearly three months in the hospital unit, the health ministry said. Spread by rodents, hantavirus is a rare virus for which no vaccines or specific treatments exist. The cases from the cruise ship pale in comparison to the tens of thousands of hantavirus infections recorded worldwide every year, which mostly involve humans being infected by close contact with a rodent.
