A French nurse who contracted Ebola while volunteering for Doctors Without Borders (MSF) in Liberia has been cured of the deadly virus, the French health minister has said.
The nurse, who has not been identified, "is now cured and has left hospital," Marisol Touraine said in a statement.
The first French national to be infected with the virus was airlifted back to France on 19 September and received experimental treatment at a military hospital on the outskirts of Paris.
Ebola has killed more than 3,300 people in west Africa in the worst ever outbreak of the disease.
Ms Touraine authorised the use in France of three experimental drugs for the treatment of Ebola, including antiviral medicine Avigan, produced by Japanese firm Toyama Chemical, a subsidiary of FujiFilm Holdings.
The company said the nurse had been given Avigan, which was approved in Japan in March.
There is no licensed treatment or vaccine for Ebola.
Of several prototype treatments in the pipeline, one dubbed ZMapp has been fast-tracked for use, developed by Mapp Biopharmaceutical in California, in conjunction with the US Army.
Texas Ebola patient in critical condition: hospital
Meanwhile, the first person to be diagnosed with Ebola on United States soil is now in a critical condition, health officials have said.
He was previously described as seriously ill.
"Mr Duncan is in critical condition," the Texas hospital treating Thomas Eric Duncan, who travelled from Liberia to Texas in late September, said in a brief statement.
The update came as US authorities said none of the individuals believed to have had exposure to Mr Duncan, including nine deemed to be at high risk, had shown any signs of Ebola infection.
"We are confident that none of those with definite contact had any symptoms related to Ebola, none of them had fever," said Tom Frieden, the director of the US Centers for Disease Control and Prevention.
The nine people deemed at high risk would be monitored closely, Mr Frieden said.
"We will be looking very closely particularly at the nine individuals in the coming days, understanding that the peak period after exposure is about eight to nine days but can be as long as 21 days," he said.
Mr Duncan was initially sent home when he first sought medical care, leaving a four-day span when he was sick and contagious while in contact with others, sparking concern over how many others may have been exposed.
