I had a cousin that worked at a research facility (in Maryland I think, heck this was back in the ‘70s) where they studied the deadliest diseases known to exist. Told me the story of how you got to and from the hot room. When you left, you stepped into this small compartment which sealed off and flooded your suit with some kind of disinfectant. Next you went into another sealed compartment that flooded your suit with water, then into another compartment that did the same thing. Finally a sealed compartment where you stripped, put all of your clothing into some kind of hampers. Next another sealed compartment that sprayed you completely with some kind of cleaner. Then into two successive compartments that sprayed you with what appeared to be water. Finally into a small dressing area (mainly for underwear) and then into the final dressing area.
He told me this story around the thought, “I'll tell you, you never want to go in there if you think there is even the slightest chance of diarrhea, because this whole process takes nearly 30 minutes.”
I suspect something not even one tenth that thorough is being followed with regard to Ebola.
