Ever wonder why zombies want to eat brains? So they can prevent strategizing like this.
Working with a professor and two other graduate students, Munz built a mathematical model of a city of one million residents, in which an outbreak occurs when a single zombie arrives in town. He based the speed of zombie infection on the general rules you see in George Romero movies: after getting bitten, people turn into zombies in 24 hours and sometimes don't realize what's happening to them until they change.Turns out the only thing that worked was smacking the zombies down quickly and early. Word to the wise, people!
When he ran the model on a computer, the results were bleak. "After 7 to 10 days, everyone was dead or undead," he says. He tried several counterattacks. Quarantining the zombies didn't work; it only bought a few extra days of survival for humanity. Even creating a "cure" for zombification led to a grim result. It was possible to save 10 to 15 percent of the population, but everyone else was a zombie. (The cure in his model wasn't permanent; the cured could be rebitten and rezombified.)
