The second American infected with Ebola has arrived in Atlanta for treatment at Emory University Hospital. The plane carrying Nancy Writebol first landed at Bangor International Airport in Maine Tuesday for refueling and federal customs inspection before flying to Atlanta. Wearing white Tyvek protective suits like the workers taking care of her, Writebol was wheeled on a gurney into the hospital from an ambulance that brought her from the airport. She'll join Ebola-infected colleague Dr. Kent Brantly in Emory's isolation ward. Both Americans received an experimental serum that appears to be helping them survive the extremely lethal virus, which has a fatality rate as high as 90 percent.
