It has been one year since Emory University Hospital prepared to accept the first patient to be treated for Ebola virus disease in the United States. Over the next three months, the hospital's Serious Communicable Disease Unit successfully treated four patients, and over the past year physicians, nurses and scientists have worked with the CDC and other institutions to share lessons of preparedness, prevention and treatment with colleagues throughout the United States and in West Africa and to conduct research aimed at developing more effective vaccines and therapies.
