Meanwhile, Emory University Hospital planned to hold a news conference Thursday morning to discuss both patients' discharge.
Alison Geist, a spokeswoman for Samaritan's Purse, told the Associated Press she did not know the exact time Dr. Kent Brantly would be released but confirmed it would happen Thursday.
Meanwhile, Franklin Graham, president of Samaritan's Purse, said in a statement that Brantly has recovered.
"Today I join all of our Samaritan's Purse team around the world in giving thanks to God as we celebrate Dr. Kent Brantly's recovery from Ebola and release from the hospital," Graham's statement said.
Brantly and Nancy Writebol were flown out of the west African nation of Liberia earlier this month and have been getting treatment for the deadly disease in an isolation unit at the hospital. The two were infected while working at a missionary clinic outside Liberia's capital.
The Ebola outbreak has killed 1,350 people and counting across West Africa.
Ebola is spread only through direct contact with the bodily fluids of sick people experiencing symptoms.
