Engrossing true stories of the pioneers of epidemiology who risked their lives to find the source of deadly diseases—now revised to include updated information and a new chapter on Covid-19.

More people have died in disease epidemics than in wars or other disasters, but the process of identifying these diseases and determining how they spread is often a terrifying gamble. Epidemiologists have been ignored, mocked, or silenced all while trying to protect the population and identify “patient zero”—the first person to have contracted the disease, and a key piece in solving the epidemic puzzle.

Patient Zero tracks the gripping tales of eight epidemics and pandemics—how they started, how they spread, and the fight to stop them. This revised edition combines a brand-new design with updated information and features diseases such as Spanish Influenza, Ebola, and AIDS, as well as a new chapter on Covid-19.
