Where do pandemics come from? In this Zombified episode, author and science communicator David Quammen talks with us about the origins of viral diseases and the stories behind how pandemics start and spread. We talk about bats and their role in zoonotic diseases, the origins of AIDS, and David presciently warns of the Zombie Apocalypse by way of single stranded DNA viruses (despite the fact that we recorded this episode before the COVID19 outbreak).
