What does an Ebola isolation ward look like?

The seven-bed, 4,000-square-foot biocontainment unit at the National Institutes of Health Clinical Center in Bethesda, Md., is a state-of-the-art facility built to keep the world’s scariest pathogens from escaping. The four U.S. facilities are all different — NIH’s even has a gym — but they contain many of the same things. This layout is based on the unit at Emory University in Atlanta.
