U.S. aid worker, Dr. Kent Brantly, was infected with the Ebola virus but recovered and was released from Emory University Hospital on Thursday. Another aid worker, Nancy Writebol, who also contracted the deadly virus while working in West Africa, left the hospital on Tuesday. Brantly and Writebol were treated with an experimental treatment called Zmapp, but it is not clear whether the drug helped them recover or they improved on their own, as others who survived the disease did. Doctors at the hospital in Atlanta, Georgia said that discharging patients who were infected with the deadly virus poses no public health threat.
