Two U.S. health workers infected with Ebola in Liberia were released from Emory University Hospital in Atlanta after treatment there helped wipe out the deadly virus from their blood.

Kent Brantly, a doctor, was discharged Thursday. Nancy Writebol, an aid worker, was released Aug. 19, the hospital said in a statement. They had been evacuated to the U.S. for treatment and are expected to make a full recovery.

"Today is a miraculous day," Brantly said at a news conference in Atlanta. "I am thrilled to be alive, to be well, to be reunited with my family."
