France has detected its first sexually-transmitted case of the Zika virus.
A senior health official announced today that a woman whose partner travelled to Brazil, the epicentre of the virus outbreak, was affected.
Earlier this week, U.S. officials said they were investigating 14 reports of the mosquito-borne disease that may have been transmitted through sex - including to several pregnant women.
Francois Bourdillon, head of France's Institute for Public Health Surveillance, said the infected woman was the country's "first confirmed indigenous case of transmission".
"This was a woman who had never travelled. Her partner had come from Brazil, so she was tested," Mr Bourdillon said, adding that both patients were doing well.
There is no cure or treatment for the virus which has so far spread to more than 30 countries.
The first case of the Zika virus has been confirmed in South Africa, health authorities have said.
The mosquito-borne virus was found in a Columbian man visiting Johannesburg.
Health Minister Aaron Motsoaledi said: "The businessman presented with fever and a rash approximately four days after arrival in South Africa but is now fully recovered."
The World Health Organization declared the outbreak a global public health emergency on February 1.
A 61-year-old woman has been confirmed as the first Zika case in Trinidad and Tobago, the country's health ministry said.

More than 200,000 Brazilian soldiers have been out on the streets today as part of an education drive to combat the spread of the Zika virus.
The troops are handing out leaflets and aim to reach three million homes in 350 cities.
