Even with the glass between them, their reunion was an emotional one, said missionary David Writebol about seeing his wife, Nancy, for the first time in three weeks on Sunday.
Nancy is one of two Americans
recovering from Ebola at an Atlanta hospital.
"I have had the great joy to be able to look through the isolation room glass and see my beautiful wife again," he said in a statement
released by SIM
, the Charlotte, North Carolina-based missionary group that sponsored the couple's work in Liberia, where Nancy contracted the disease.
"We both placed our hands on opposite sides of the glass, moved with tears to look at each other again," he said. "She was standing with her radiant smile, happy beyond words."
Writebol, 59, just completed a 21-day quarantine to ensure he did not have Ebola. Nancy arrived at Atlanta's Emory University Hospital
on Aug. 5.
Dr. Kent Brantley
, who arrived on Aug. 2, released an update on his condition last Friday.
"I am recovering in every way," Brantly, 33, said in a statement
released by Samaritan's Purse
, the group with which he was working in Liberia.
"I thank God for the healthcare team here who is giving me compassionate, world-class care," he said. "I am more grateful everyday to the Lord for sparing my life and continuing to heal my body."
He said he has "a few hurdles to clear" before he can go home.
David Writebol said he is looking forward to seeing his wife outside the isolation room where she is being treated.
"She is continuing to slowly gain strength," he said, "eager for the day when the barriers separating us are set aside, and we can simply hold each other again."
