Let's get right into it:
I got this thought stuck in my head that either in the TV series or in the telltale game the survivors get the idea that it doesn't even have to be a bite but that a mere scratch caused by the walkers would be enough to turn you into one of them. Is that true or was that something they discovered before they knew that you just need to die in order for you to turn?
Edit: Right off the bat I want to apologize because I didn't make this clear enough. My question was: does a scratch kill you as well? I'm not talking about infection and stuff like that, we all know that everybody is infected per se. Regardless of that:thanks for your feedback!
Final edit: case closed thanks to RedGrimes!
