The two American patients diagnosed with Ebola in July have been released from the hospital in Atlanta, Georgia, where they were receiving treatment.

After 19 days in isolation in a special unit at the Emory University Hospital, Dr. Kent Brantly, 33, was discharged on Thursday. Nancy Writebol, 59, who had been held with Brantly, was released on Tuesday, which the university revealed on Thursday as well. Both have recovered from the deadly virus.

“Today is a miraculous day,” Brantly, who got infected while working in Liberia for the U.S. aid group Samaritan’s Purse on July 23, said during a press conference at the hospital, where he thanked and hugged the medical staff.

“God saved my life,” he added.

Ebola has a fatality rate of up to 90%; the latest strain has spread throughout West Africa over the past few months, killing more than 1,200 and infecting more than 2,000 in Guinea, Liberia, Nigeria and Sierra Leone. It is already the worst outbreak in history.

Brantly is not the first to recover from Ebola. While no cure exists for the virus, treatment is available.

In his time at the Emory University Hospital, Brantly was received ZMapp, an experimental serum that has yet to receive approval from the U.S. Food and Drug Administration (FDA), though the U.N.’s World Health Organization recently said it was “ethical” to use during the current Ebola outbreak. (It’s still unclear whether ZMapp was key to Brantly and Writebol’s recovery.)

On Aug. 8, Brantly said he was “growing stronger every day,” indicating that the treatment might have been working.

Dr. Bruce Ribner, the lead physician who treated Brantly and Writebol, said that their discharge “poses no public health threat.” He acknowledged the concern among the American public regarding the virus, but said it is time for people to deal with it more rationally: “We cannot let our fears dictate our actions.”
