Another Sierra Leonean doctor has died from Ebola, the 10th to succumb to the disease, a health official said Sunday.

Dr. Aiah Solomon Konoyeima died Saturday, according to Chief Medical Officer Dr. Brima Kargbo. His death came a day after two other doctors died from Ebola, emphasizing the tremendous toll the disease has taken on health care workers.

Konoyeima worked at a children's hospital in the capital and tested positive for Ebola about two weeks ago. He was treated at the Hastings Ebola Treatment Center, which is staffed exclusively by Sierra Leonean medical personnel, as compared to many other treatment units, which are run by international organizations or employ some foreign staff.

Because Ebola is transmitted through the bodily fluids of the sick and dead, it is sometimes called the "caretakers' disease." Hundreds of health workers have been infected in this outbreak.

In the current outbreak, Ebola has sickened more than 17,500 people, mostly in Guinea, Liberia and Sierra Leone. Of those, about 6,200 have died. It is currently spreading fastest in Sierra Leone.
