(AP Photo/David Goldman) (Newser) – Emory University Hospital is preparing to treat its third Ebola patient, who landed at Dobbins Air Reserve Base outside Atlanta this morning. The hospital said the patient would be treated in its isolation unit. Last month, two aid workers who contracted Ebola while working in Liberia were treated successfully at Emory. Another US patient, an American doctor, is being treated in Nebraska. The World Health Organization said yesterday that one of its doctors working in an Ebola treatment center in Sierra Leone had tested positive for the disease and was to be evacuated. The patient's identity hasn't been released.
