A surgeon from Sierra Leone, who is critically ill with Ebola, has arrived in the US for treatment.
Martin Salia, who has US residency and is married to an American, has been taken to a hospital in Nebraska.
Meanwhile France has advised its citizens not to travel to parts of Mali, following the deaths of three people there from the disease.
More than 5,000 people have been killed in the current Ebola outbreak — almost all of them in West Africa.
Sierra Leone is one of the three worst affected countries, along with Liberia and Guinea.
Dr Salia, 44, had been working as a general surgeon at Kissy United Methodist Hospital in the Sierra Leone capital, Freetown.
It is not clear whether he was involved in the care of Ebola patients, BBC informs.
