Dr. Kent Brantly, one of the 2 American doctors infected with the ebola virus is released from Atlanta's Emory University Hospital on Thursday.
The other doctor, Nancy Writebol, was released earlier this week.
Brantly's blood tests now show he is clear of the virus.
He was treated with an experimental drug known as ZMapp
When doctors at Emory University Hospital, where Brantly received treatment, were asked about the role that ZMapp played in the recoveries, the resonse was entirely uncertain. They "do not know whether it helped them, whether it made no difference," or whether it might have delayed their recovery.
Dr. Bruce Ribner, director of Emory's Infectious Disease Unit said he also did not know whether Brantly was helped by a blood transfusion he received from a young Ebola survivor in Liberia.
A news conference was held at 10:00am, where Dr. Brantly gave a statement before leaving the hospital.
“Through the care of Samaritan's Purse, and the group in Liberia, the use of an experimental drug, and the expertise and resources of the health care team at Emory University Hospital, god saved my life. “
Meanwhile, the number of new ebola cases continues to grow.
The World Health Organization said there are 1350 confirmed, suspected, and probable ebola deaths in West Africa.
