Ebola outbreak: New York doctor Craig Spencer tests positive.-Video
A New York doctor who recently returned from Ebola-hit Guinea in West Africa has tested positive for the disease.
Dr Craig Spencer, who treated Ebola patients while working for the charity Medecins Sans Frontieres (MSF), came down with a fever on Thursday, days after his return, officials say.
He is the first Ebola case diagnosed in New York, and the fourth in the US.
Meanwhile, one million doses of an Ebola vaccine will be produced by the end of 2015, it has been announced.
The World Health Organization said "several hundred thousand" will be produced in the first half of the year.
Mali has confirmed its first case of Ebola after a two-year-old girl tested positive for the virus.
More than 4,800 people have died of Ebola - mainly in Liberia, Guinea and Sierra Leone - since March.
