DV,
No concrete here, but a little more food for thought. ... I served in the Air Force stationed in West Germany during the Cold War. We constantly trained for a war with the Warsaw Pact forces and we assumed they would use chemical weapons including nerve agents that can kill with a wiff or a drop on the skin. Getting suited up and operating in chemical warfare suits was no fun, but it wasn't that hard to do. The hard part was getting them off after (simulated) exposure without getting contaminated. The decontamination process was lengthy and required other personnel to also be in proximity to the contaminated person. Peacetime training never reveals subtle lapses that might kill someone in a real situation. But it wouldn't surprise me a bit to find that people could survive the initial chemical weapons attack only to die while trying to get out of the contaminated gear. Same reasoning could apply to people wearing protecting gear around a disease like ebola.
