True, but it is still a horrible transmission vector, just ask any contagion expert. Relying on biting, especially with such obvious and violent symptoms, it wouldn't spread beyond the initial town. Too easy to spot, and too easily stopped.

The entire threat of zombies (especially the virus form, versus the voodoo form) is the large number, but the common propagation method simply doesn't allow that number to be reached. That was what caused me to consider alternatives, which led to this thread.
