The Italian woman had a high fever and was put under medical supervision on arrival at Istanbul Ataturk Airport, Cihan news agency reported.
She had travelled on a Turkish Airlines flight from Kano in Nigeria, where there have been 12 confirmed cases and four deaths of the Ebola virus.
The woman was taken from the airport to Istanbul’s Haseki Training and Research Hospital, Cihan said.
When contacted by The Local, a spokeswoman for Turkish Airlines was not immediately able to comment on the report. An airport spokesperson was not available to discuss the case.
The Ebola outbreak has so far killed 1,350 people, including suspected and probable cases of the disease, the World Health Organization (WHO) said this week.
The worst-affected countries are Liberia, Guinea and Sierra Leone, although fears have been raised that the virus could spread internationally through air travel. As of Wednesday, however, there were no confirmed Ebola cases outside West Africa, WHO said.
