Another US Doctor in Liberia Contracts Ebola

Elwa hospital

Another American missionary doctor has tested positive for Ebola in Monrovia, Liberia; making him the third American health care worker to contract the virus.

The name of the doctor, who worked for the Christian aid group SIM, has not been released. But the group said in a statement that he did not treat Ebola patients. Instead, he saw obstetrics patients at the organization's main ELWA hospital, which is separate from its Ebola isolation unit. How he became infected is unknown.

The doctor isolated himself at the onset of symptoms and is currently being treated at the isolation facility, according to the group. They added that he is "doing well and is in good spirits."
