Dr. Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, told NBC on Sunday that Brantly's condition seems to have improved and that it was encouraging to see Brantly walk out of the ambulance unassisted when he arrived at the hospital.
Frieden said he understands the public's concerns about Ebola, and the public health role is to ensure that the infection is not spread.
"Ebola is very deadly. And it's normal to be scared of deadly diseases," he said.
Few of those nearest the hospital Saturday seemed concerned.
"I just think it's a blessing that we can help possibly make the infected person's life a little more tolerable," said Ashley Wheeler, who was shopping just down the street on Saturday. "If I were that person I would want my country to help me the best way they could."
Emory's infectious diseases' unit was created 12 years ago to handle doctors who get sick at the CDC. It is one of about four in the country equipped with everything necessary to test, treat and contain people exposed to very dangerous viruses.
In 2005, it handled patients with SARS, which unlike Ebola can spread when an infected person coughs or sneezes.
In fact, the nature of Ebola — which is spread by close contact with bodily fluids and blood — means that any modern hospital using standard, rigorous, infection-control measures should be able to handle it.
Still, Emory won't be taking any chances.
"Nothing comes out of this unit until it is non-infectious," said Dr. Bruce Ribner, who will be treating the patients. "The bottom line is: We have an inordinate amount of safety associated with the care of this patient. And we do not believe that any health care worker, any other patient or any visitor to our facility is in any way at risk of acquiring this infection."
Ribner also said the patients deserve help.
"They have gone over on a humanitarian mission, they have become infected through medical care and we feel that we have the environment and expertise to safely care for these patients and offer them the maximum opportunity for recovery from these infections," he said Friday.
Amber Brantly was heartened to see her husband climb out of the ambulance that met his plane at Dobbins Air Reserve Base outside Atlanta. He climbed out dressed head to toe in white protective clothing, and another person in an identical hazardous materials suit held both of his gloved hands as they walked gingerly inside.
"It was a relief to welcome Kent home today. I spoke with him, and he is glad to be back in the U.S.," she said in a statement. "I am thankful to God for his safe transport and for giving him the strength to walk into the hospital."
