WHO: Ebola cases cross 20,000

More than 20,000 people have been infected by the deadly virus in Sierra Leone, Liberia and Guinea alone, WHO says.

The WHO also said in a statement on Monday that there have been more than 7,842 Ebola-related deaths recorded, and 20,081 cumulative cases of infection in the three worst hit countries.
More than a third are laboratory-confirmed cases in Sierra Leone, which has become the worst-hit country in the worst outbreak of the disease on record, the organisation said.
