The patient will be treated at Emory University Hospital in the same isolation unit as two other patients who were discharged after recovering from the virus, the hospital said in a statement.
Medical workers have been hit hard by the epidemic, the worst since Ebola was discovered in 1976. As of late August, more than 240 Healthcare workers had developed the disease and more than 120 had died, the WHO said.
The outbreak has killed some 2,100 people overall in Guinea, Sierra Leone, Liberia and Nigeria, and has also spread to Senegal.
Emory's isolation unit is equipped with unique tools and infrastructure that provide a high level of clinical isolation for people exposed to serious infectious diseases, the hospital said.
