Update — 11:22 a.m. ET:
Dr. Kent Brantly was discharged from Emory Hospital today after completely recovering from the Ebola virus.
In a press conference, the missionary thanked God, global ministry groups SIM and Samaritan's Purse, the experimental drug ZMapp, and the medical team at Emory Hospital for his treatment and recovery.
"Today is a miraculous day," he said. "I am thrilled to be alive, to be well, and to be reunited with my family.
"I am forever thankful to God for sparing my life and am glad for any attention my sickness has attracted to the plight of west Africa in the midst of this epidemic. Please continue to pray for Liberia and the people of west Africa, and encourage those in positions of leadership and influence to do everything possible to bring this Ebola outbreak to an end."
He said he will be going away with his family for a period of time to recover from the physical and emotional ordeal.
Nancy Writebol, the other American missionary who contracted Ebola, was tested clear of the virus and discharged from Atlanta's Emory Hospital on Tuesday, Aug. 9, SIM said in a press release.
SIM said that Writebol "and her husband, David, have gone to an undisclosed location to rest and spend time with one another."
David Writebol issued a statement today saying his wife is free of the virus but that the "lingering effects of the battle have left her in a significantly weakened condition."
He added: "During the course of her fight, Nancy recalled the dark hours of fear and loneliness, but also a sense of the deep abiding peace and presence of God, giving her comfort. She was greatly encouraged knowing that there were so many people around the world lifting prayers to God for her return to health. Her departure from the hospital, free of the disease, is powerful testimony to God's sustaining grace in time of need."
"The discharge of both patients poses no public health threat," Dr. Bruce Ribner, director of Emory's Infectious Disease Unit, which led the medical team treating Writebol and Brantly, said at today's press conference.
The condition of two doctors and a nurse infected by Ebola in Liberia has improved after they received the same experimental drug given to both American patients, the World Health Organization said Thursday.
Clinicians working with the Ebola patients told WHO that the nurse and one of the doctors showed a "marked improvement" after receiving ZMapp. The second doctor is still in a serious condition but has "improved somewhat."
The San Diego-based manufacturer of ZMapp said that the limited supplies of the drug are now exhausted.
The pair contracted the Ebola virus while working in a missionary clinic outside the Liberian capital, Monrovia.
The Ebola virus is spread by coming into contact with the bodily fluids of infected people.
During the current outbreak, 1,350 people have died across West Africa. Click here for a breakdown of the latest World Heath Organization figures on the disease.
