A New York Times article on the Year in Ideas features an idea about zombie science.
Philip Munz, a graduate student at Carleton University in Ottawa, an apparent fan of zombie genre films, realized that people who get bitten by zombies could be regarded as a classic paradigm of infectious spread. Munz applied the tools of epidemiology to the potential public health crisis of a zombie outbreak using the George Romero rules of zombification.
Munz, along with a professor and two other graduate students built a mathematical model of a city of one million residents in which an outbreak occurs when a single zombie arrives in town. In this model, people turn into zombies with 24 hours of infection, and don't always realize they are infected. The results were bleak.
"After 7 to 10 days, everyone was dead or undead," Munz says. Even quarantining the zombies only bought a few extra days of survival, and a cure might only save as few as 10-15% of the population (which could still be rezombified). The only winning solution relied on an immediate policy of "eradication," then the zombies can be beaten.
I suspect Mr. Romero feels chuffed that his classic remedy for a zombie epidemic is the best choice.
