You see things like that in movies where they have an airlock with a suit attached on the other end. I think they might have bio-weapon labs like that.
The problem would be, they are expensive and all that. We have about 19 total isolation beds like that. nationally.
How much do we pay for a single F-22? The problem is that they have put so little thought into how to contain Ebola. The first outbreak, in a rural area, was contained and the threat ended as soon as the victims were mostly dead. So here they are, unprepared, as the disease works its way through urban populations. May be like a war. all you can do is to minimize the casualties, and attack the objective with sufficient force.
