They literally say "don't get it on your skin or in your eyes". It's also why they wear huge coats and gloves.
(episode was good)
Believe it or not I have a major continuity nitpick with the second episode. I haven't seen it yet and don't want to spoil but it has to do with how they get through the zombie crowd: if I am in an environment with a highly deadly communicable disease with no known cure that is proven to be passed through fluid contact, THE LAST THING I'm GONNA DO IS SMEAR IT ALL OVER ME! That's like saying "Hey guess what? They can't smell AIDS!"
Exactly, and then it RAINS lol, but while they're walking about, you get to see WICKED zombie character development. Different levels of zombie consciousness, etc. Pack mentality and reactivity.
remember in the remake when they discover they don't react to dogs, just people? Same idea.
