(CNN) -- An airborne virus is rapidly turning people into zombies. Two-thirds of humanity has been wiped out. Scientists desperately look for a cure, even as their own brains deteriorate and the disease robs them of what we consider life.
Relax, it's only fiction -- at least, for now. This apocalyptic scenario frames the new novel "The Zombie Autopsies" by Dr. Steven Schlozman, a child psychiatrist who holds positions at Harvard Medical School and the Massachusetts General Hospital/McLean Program in Child Psychiatry.
You might not expect someone with those credentials to take zombies seriously, but it turns out the undead are a great way to explore real-world health issues: why certain nasty diseases can destroy the brain, how global pandemics create chaos and fear, and what should be done about people infected with a highly contagious and incurable lethal illness.
