Scientists have confirmed that the Ebola virus is mutating - and could become more contagious.
Researchers at the Institute Pasteur in France say they have detected substantial changes to the genetic code of the virus.
Although they don't yet know what effect that will have on the epidemic, they fear the virus could spread from person to person more easily.
In previous Ebola outbreaks, the virus has only infected a few dozen people and died out within weeks.
