Monrovia - Liberia on Friday started a clinical trial of experimental Ebola drug ZMapp, a health official said.
About 1 000 adults and children infected with the virus are participating in the trial in two treatment centres in the capital, Monrovia, said Jerry Brown, one of the trial's principal co-ordinators.
Liberia's health department is conducting the trial with support from the United States national institute of allergy and infectious diseases.
