ATLANTA -- The first person infected with Ebola to be brought to the United States from Africa was safely escorted into a specialized isolation unit Saturday at one of the nation's best hospitals, where doctors said they are confident the deadly virus won't escape.
Dr. Kent Brantly and his assistant Nancy Writebol will be treated in Emory's isolation unit for infectious diseases, created 12 years ago handle doctors who get sick at the CDC. It is one of about four in the country equipped with everything necessary to test and treat people exposed to very dangerous viruses.
In 2005, it handled patients with SARS, which unlike Ebola can spread like the flu 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 noninfectious," 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."
Amber Brantly was heartened to see her husband climb out of the ambulance that met his plane at Dobbins Air Reserve Base outside Atlanta.
"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."
Inside the unit, patients are sealed off from anyone who doesn't wear protective gear.
"Negative air pressure" means air flows in, but can't escape until filters scrub any germs from patients. All laboratory testing is conducted within the unit, and workers are highly trained in infection control. Glass walls enable staff outside to safely observe patients, and there's a vestibule where workers suit up before entering. Any gear is safely disposed of or decontaminated.
Family members will be kept at a distance for now, the doctors said. The unit "has a plate glass window and communication system, so they'll be as close as 1-2 inches from each other," Ribner said.
Dr. Jay Varkey, an infectious disease specialist who will be treating Brantly and Writebol, gave no word Saturday about their condition. Both have been described as critically ill after treating Ebola patients at a missionary hospital in Liberia, one of three West African countries hit by the largest outbreak of the virus in history.
There is no cure for the virus, which causes hemorrhagic fever that kills as many as 60-80 percent of the people it infects in Africa. There are experimental treatments, but the missionary hospital had only enough for one person, and Brantly insisted that Writebol receive it. His best hope in Africa was a transfusion of blood including antibodies from one of his patients, a 14-year-old boy who survived thanks to the doctor.
There was also only room on the plane for one patient at a time. Writebol will be next, following the same route to Emory in several days.
