Numbers released today by WHO include about 200 new cases since data was published yesterday. More than 6,000 people have died.
The vast majority of the infected are in Guinea, Liberia and Sierra Leone.
Also today, Sierra Leonean Health Ministry spokesman Jonathan Abass Kamara said that Dr. Thomas Rogers has tested positive for the disease and was admitted a day earlier to the British-built treatment center in Kerry Town, near the capital. Rogers had been working at Connaught Hospital in Freetown.
