Brantley made comments at a press conference today at Emory Hospital.

"As a medical missionary I never expected to find myself in this position," Brantly said. "Ebola was not on our radar."

After Ebola made its way to Liberia, Brantly said he sent his family back to the United States and poured himself into his work treating patients with the virus.

"We took every precaution to protect ourselves from this dreaded disease," Brantly said. "I woke up three days later feeling under the weather" and was later diagnosed with the deadly virus.

Brantly thanked the hospital workers who cared for him in Atlanta and administered the experimental serum that cured him. "Above all I am grateful to God for sparing my life," Brantly said.

The Ebola virus has killed more than 1,300 people in West Africa, reports the World Health Organization, which recently issued a warning that the outbreak was vastly underreported.
