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. Diseases ranging from malaria to cancer have shaped the social landscape--sometimes through brief, furious outbreaks, and at other times through gradual occurrence, control, and recurrence. Grob integrates statistical data with particular peoples and places while giving us the larger patterns of the ebb and flow of disease over centuries. Throughout, we see how much of our history, culture, and nation-building was determined--in ways we often don't realize--by the environment and the diseases it fostered. The way in which we live has shaped, and will continue to shape, the diseases from which we get sick and die. By accepting the presence of disease and understanding the way in which it has physically interacted with people and places in past eras, Grob illuminates the extraordinarily complex forces that shape our morbidity and mortality patterns and provides a realistic appreciation of the individual, social, environmental, and biological determinants of human health.

Findings from the field of evolutionary biology are yielding dramatic insights for health scientists, especially those involved in the fight against infectious diseases. This book is the first in-depth presentation of these insights. In detailing why the pathogens that cause malaria, smallpox, tuberculosis, and AIDS have their special kinds of deadliness, the book shows how efforts to control virtually all diseases would benefit from a more thorough application of evolutionary principles. When viewed from a Darwinian perspective, a pathogen is not simply a disease-causing agent, it is a self-replicating organism driven by evolutionary pressures to pass on as many copies of itself as possible. In this context, so-called "cultural vectors"--those aspects of human behavior and the human environment that allow spread of disease from immobilized people--become more important than ever. Interventions to control diseases don't simply hinder their spread but can cause pathogens and the diseases they engender to evolve into more benign forms. In fact, the union of health science with evolutionary biology offers an entirely new dimension to policy making, as the possibility of determining the future course of many diseases becomes a reality. By presenting the first detailed explanation of an evolutionary perspective on infectious disease, the author has achieved a genuine milestone in the synthesis of health science, epidemiology, and evolutionary biology. Written in a clear, accessible style, it is intended for a wide readership among professionals in these fields and general readers interested in science and health.

Not far from Chattanooga in northern Georgia, the Confederacy won one of its most decisive battles at Chickamauga. This guide uses firsthand accounts to illustrate how this skirmish, only two days long, turned into the second-bloodiest battle of the Civil War with over 34,000 Union and Confederate soldiers killed, wounded, or captured. The U.S. Army War College Guides to Civil War Battles series was developed for “staff rides” on key battlefields by military professionals. Eyewitness accounts by battle participants make these guides invaluable resources for visitors to the national military parks and armchair strategists alike who want a greater understanding of five of the most devastating yet influential years in our nation’s history. This is an on-the-ground guide with explicit directions to points of interest and maps—illustrating the action and showing the details of troop position, roads, rivers, elevations, and tree lines as they were more than 150 years ago—that help bring the battle to life. In the field, these guides can be used to re-create each battle’s setting and proportions, giving the reader a sense of the tension and fear each soldier must have felt as he faced his enemy.
