Another doctor has died from the Ebola virus in Sierra Leone.

He had contracted the disease while treating infected patients.

More than 20 health workers have so far lost their lives to the virus in that country.

Earlier, Liberia lifted a quarantine cordon on a large slum it sealed off more than a week ago to contain the spread of the virus.
