The Deadly Truth chronicles the complex interactions between disease and the peoples of America from the pre-Columbian world to the present. Grob's ultimate lesson is stark but valuable: there can be no final victory over disease. The world in which we live undergoes constant change, which in turn creates novel risks to human health and life. We conquer particular diseases, but others always arise in their stead. In a powerful challenge to our tendency to see disease as unnatural and its virtual elimination as a real possibility, Grob asserts the undeniable biological persistence of disease.
