Ebola virus cases in the United States

On September 30, 2014, the first case of Ebola virus disease was diagnosed in the United States. It came from a 42-year-old Liberian national, Thomas Eric Duncan. Even before Duncan's diagnosis, three Americans had been medically evacuated from Africa and treated in the United States for Ebola virus disease. This was during the current Ebola virus epidemic in West Africa. Two were treated at Emory University Hospital's isolation unit and one at Nebraska Medical Center.
