I only say either/or because I want to say that a character in the comics turned after dying without being bit or infected, but I can't remember a name. I really need to read through them again!
Edit - Basically, it's the fever and the injury from the bite or attack that kills them more than the "becoming a zombie" thing. If they can get that under control, then they won't turn. At least I think that's how it is in this zombie-verse.
