We all know that if you get bit by a zombie, you then become a zombie yourself.
If a mosquito bites a Zombie, then bites you, you still become a zombie right?
It's common to get spattered by zombie blood when killing zombies. This does not turn you into a zombie.
But what if you slice open a zombie, dive in with both hands and smother yourself in zombie blood and zombie organs. You would do this in order to smell just like a zombie to avoid zombies attacking you. But wouldn't that zombie blood have a tendency to infect you by means of any little knick and cut you may have spread the zombie blood over?
Or does zombie blood become harmless once it is exposed to air?
