French Health Minister Stéphanie Rist said Tuesday there was “no evidence to suggest widespread circulation of the virus within the country” after several passengers returned from the MV Hondius cruise ship, where an outbreak was reported.
She also said it was not yet certain whether the hantavirus strain linked to the ship had mutated, although officials were “rather reassured.”
The World Health Organization said there was no indication the strain on the ship was unusual beyond its location. The outbreak has been linked to the Andes strain of hantavirus, and officials have consulted Argentina, where an outbreak involving the same strain ended in 2019.
A French woman repatriated from the MV Hondius remained in intensive care on a ventilator after developing a severe case, a doctor said. The woman was one of five French passengers flown back from the ship and placed in isolation in Paris. She became very unwell Sunday night and tested positive.
“The patient now has the most severe form of cardiopulmonary presentation,” Dr. Xavier Lescure told a press conference at the health ministry.
“She is on an artificial lung and a blood bypass to allow her, we hope, to get through this stage.”
He said she was older than 65 and had pre-existing conditions, without giving further details.
Three passengers from the Hondius — a Dutch couple and a German woman — died, while others became ill with the disease, which usually spreads among rodents.
The World Health Organization confirmed nine cases and said more were expected because of passenger interactions before the virus was detected. It also said there was no sign of a wider outbreak. No vaccine or specific treatment exists for hantavirus.
Health officials said the risk to global public health was low and cautioned against comparisons to the Covid-19 pandemic.
