Dozens of people are being monitored in Mali after the country confirmed its first case of Ebola.
The patient is a two-year-old girl who recently arrived from Guinea, which along with Liberia and Sierra Leone has seen most of the 4,800 deaths.
However, the Malian health ministry says her condition is now improving.
The World Health Organization (WHO) has meanwhile announced that hundreds of thousands of vaccine doses should be available in the first half of 2015.
