Of course people get tired and so forth while using the PPE, especially in hot climates.
The issue that I see with the CDC is that Dr. Friedan is a total nerd, so that even though he communicates the correct information, people don't want to believe him. He appears to be used to speaking to highly technical audiences, not the general public. And the general public is not familiar with scientists.
Nerd doesn’t cut it. Ebola is a class 4 biological threat. Locate the source, contain, eradicate. Friedan is being misleading about it.
