The two American aid workers who contracted Ebola while doing missionary work in West Africa have been cured from the diseased after receiving treatment at a U.S hospital.

Dr. Kent Brantly and Nancy Writebol were transported to a Georgia hospital after they were both diagnosed with the deadly virus earlier this summer. Dr. Brantly arrived on Aug. 2 after contracting the disease while working in a Liberian Ebola ward with the Christian-based organization Samaritan's Purse.

Although over 1,350 West Africans have died from Ebola, American doctors were able to save the Christian medical workers through the use of experimental treatment.

After being released from Emory University Hospital in Atlanta, Dr. Brantly delivered a speech calling his recovery "miraculous" and thanking God for saving his life.

"I am thrilled to be alive, to be well, and reunited with my family," said the 33-year-old doctor, adding that "today is a miraculous day," reports The New York Times.

He went on to praise God and thank the thousands of people who prayed for his health.

"I am forever thankful to God for sparing my life, and I'm glad for any attention my sickness has attracted to the plight of West Africa in the midst of this epidemic," Dr. Brantly said at the news conference, while standing by his wife, reports ABC News.

Writebol was discharged from the hospital on Tuesday. However, the North Carolina native did not appear at the conference. Instead, her husband released a statement:

"Nancy is free of the virus, but the lingering effects of the battle have left her in a significantly weakened condition. Thus, we decided it would be best to leave the hospital privately to be able to give her the rest and recuperation she needs at this time," David Writebol wrote.

During his speech, Brantly said that when Writebol, who worked for the Christian aid group SIM USA, left the hospital on Tuesday, "All she could say was 'To God be the glory.'"

Initially, critics argued against the idea of allowing the infected workers to return to the U.S. in fear that the virus would spread on American soil. However, Emory doctors backed its decision to admit Brantly and Writebol, saying that doctors gained information that would "advance the world's understanding" of the virus.

"It was the right decision to bring these patients back to Emory for treatment," Dr. Bruce S. Ribner said.
