cdc zombie : A Brief History of Zombies

A couple dressed as zombies - Danny Zucco and Sandy Olsson from the movie Grease walking in the annual Toronto Zombie Walk.

In movies, shows, and literature, zombies are often depicted as being created by an infectious virus, which is passed on via bites and contact with bodily fluids. Harvard psychiatrist Steven Scholzman wrote a (fictional) medical paper on the zombies presented in Night of the Living Dead and refers to the condition as Ataxic Neurodegenerative Satiety Deficiency Syndrome 

The rise of zombies in pop culture has given credence to the idea that a zombie apocalypse could happen. In such a scenario zombies would take over entire countries, roaming city streets eating anything living that got in their way. The proliferation of this idea has led many people to wonder “How do I prepare for a zombie apocalypse?”
