I don't really see how a zombie infection could spread. It seems like the rate at which people can kill zombies is always way higher than the rate at which Zombies infect people. If everyone could just kill on average one zombie before becoming infected themselves the number of zombies would never increase, even if everyone just shot themselves before they turned that would work. If you kill the zombie that infected you AND shoot yourself before you turn, congratulations you just reduced the zombie population by 1. And in most fictional scenarios you see people gunning down zombies right and left and not even getting infected.
It seems like the only advantage zombies ever have over normal humans is large numbers, but it's never explained how they reach those numbers to begin with. You never see the actual spreading take place. It's always one zombie at first, then flash to 3 weeks later and everyone's a zombie. How did that happen?
It seems like the zombie outbreak scenario assumes 95% of people will just let zombies walk right up to them and infect them without doing anything about it, which I doubt. Once there's even a dozen or so zombies, news will get out about it fast and people will start fleeing the area as they bring in the SWAT to clear things up.
In other words the Zombie epidemic would be halted before it even begins.
