Noted science writer William Sargent delves into the murky, often intertwined worlds of medical research and biological warfare to determine if Covid-19 was caused by accidents similar to those that have occurred from 1617 to the present.

Sargent reveals that mistakes made in dual use medical research and biological weapons facilities led to tick borne diseases in the United States, smallpox, anthrax and other germ outbreaks in Russia.

He helps unearth the factors that caused Covid-19, closing with the hope that these conditions will be altered or permanently banned in the future.
