not sure if i should do a spoiler warning, but i guess if you haven't watched season 2 this will be a spoiler
as seen earlier in the show, you turn no matter how you die. shane got stabbed by rick. moments later, he's back up as a zombie. but apparantly, zombie bites and scratches (or in dale's case, having your guts ripped out) cause infections that can be 100% fatal if given the chance to spread throughout the system.
