The World Health Organization has revealed that the deadly Ebola outbreak in West Africa could infect more than twenty thousand people before it is brought under control. The United Nations agency said the number of cases could already be four times higher than the three thousand currently registered.
 
It also called on airlines to resume vital flights across the region, saying travel bans were threatening efforts to beat the epidemic.


So far, over one thousand people in Liberia, Sierra Leone, Guinea and Nigeria have died.
