‘Zombie apocalypse’ would wipe out humankind in just 100 days, students calculate

A student study suggests that one hundred days after zombie infection spread less than 300 people would remain alive globally. After one hundred days human survivors would be outnumbered a million to one by zombies. Students worked on the assumption that a zombie would have a 90% probability of turning others into the undead. However, factoring in humans killing zombies and human reproduction rates, world’s population would eventually be able to recover.
