I saw an interesting video on the problems with the protective wear health care workers are using around ebola patients, possible ways to contaminate oneself. The gear itself does a pretty good job of protecting. The danger comes in taking it off.
A guy who is pretty familiar with the protocols demonstrated by having chocolate sauce poured on his gloves and then he smeared a little from his gloves onto the front of the suit. (Note that most local hospitals do not have the facilities to rinse off before removing the gear. The workers have to remove it "dirty".)
He then removed the gear, very slowly, demonstrating and explaining each step. It all looked good.
When he was finished and examined, he had a small smear of chocolate on the inside of one forearm, and another on the side of his neck.
