If there are openings, as there were when they didn’t cover their necks, absolutely, yes. The heat and humidity alone shouldn’t ge an issue *if* they were properly suited.
But we know for a fact that they were not properly suited because their necks were exposed.
Their sweat would carry his bodily fluids off their necks and down into the suit where they would contact it when the suit came off.
That is almost certainly why two of his nurses have had Ebola. The CDC didn’t give them the information they needed to not get sick. This is well known information, by the way. Nothing new. Nothing they shouldn’t have had in place.
I’d think that exposed skin at the neck alone would suffice, no need to be transported anywhere via sweat. Seems the salt in sweat would kill it or weaken it, but maybe it multiplies.
