Bozeman-based author David Quammen: Coronavirus epidemic not a one-time threat – “Spillover: Animal Infections and the Next Human Pandemic.”

People worried about the coronavirus epidemic should understand that outbreaks of scary new diseases that spill over from animal viruses to humans are going to keep happening, said award-winning science writer David Quammen.

“This thing, Covid-19, is not a one-time event,” he said.

Quammen, 72, a Bozeman-based author, wrote the 2012 book “Spillover: Animal Infections and the Next Human Pandemic.”
