Mathematical model describes survival rate for zombie attack.

Damn, even math is on the side of the zombies. From Wired:

It is possible to successfully fend off a zombie attack, according to Canadian mathematicians. The key is to “hit hard and hit often.”

Oh yes, somebody actually did a study on mathematics of a hypothetical zombie attack, and published it in a book on infectious disease. So, while we still don’t know what to do if a deadly asteroid takes aim at Earth, an unlikely but technically possible situation, we now know what to do in case of a zombie attack.

“An outbreak of zombies is likely to be disastrous, unless extremely aggressive tactics are employed against the undead,” the authors wrote. “It is imperative that zombies are dealt with quickly, or else we are all in a great deal of trouble.”

[...] The model focuses on modern zombies, which are “very different from the voodoo and the folklore zombies.” It takes into account the possibility of quarantine (could lead to eradication, but unlikely to happen) and treatment (some humans survive, but they still must coexist with zombies), but shows that there is only one strategy likely to succeed: “impulsive eradication.”

“Only sufficiently frequent attacks, with increasing force, will result in eradication, assuming the available resources can be mustered in time,” they concluded.

And if we don’t act fast enough?

“If the timescale of the outbreak increases, then the result is the doomsday scenario: an outbreak of zombies will result in the collapse of civilization, with every human infected, or dead,” they wrote. “This is because human births and deaths will provide the undead with a limitless supply of new bodies to infect, resurrect and convert.”
