I agree, the only way Shane could have gotten more direct was just to get bitten.
Its like he tried everything he could do to contract the virus, except actually try and get bitten.
Some people on another site are saying that you have to get bitten, and the saliva holds the virus, and that's how you contract it.
I say BS, and bad form on the writers if they make it that way. What a bunch of BS?!?!
What virus is only contracted through a bite, and a bite alone. Its not freaking venom, the virus went through their whole bodies, that's why their body died, was because of the high fever it creates, then it re-animates the brain and the rudimentary nervous system, but nothing else.
He better become a zombie or I'm calling BS on the writers.
