On Saturday, Dr. Kent Brantly arrived in Atlanta, Georgia. He is understood to be the first person carrying ebola who has been inside the United States. Dr. Brantly, of Texas, contracted the highly contagious virus while working in Liberia to help treat ebola patients, and he has been brought back to the US for intensive care at Emory University Hospital. The university is equipped with a special facility — designed in partnership with the US Centers for Disease Control — made to treat patients with extremely contagious conditions. Dr. Brantly’s co-worker, Nancy Writebol, also contracted ebola at the same clinic in Liberia. She is expected to return to the US for intensive care in a few days, according to The New York Times.
