Please Explain: Rabies

Rabies is a virus most often transmitted through the bite of an infected animal, and it has been around as long as humans have. Veterinarian Monica Murphy and  journalist Bill Wasik, authors of Rabid: A Cultural History of the World’s Most Diabolical Virus, explain the history, science, and cultural mythology surrounding rabies—and how it has spawned stories of pandemic, werewolves, and zombies.
