Explores the role disease has played in American history. More Indians were killed by smallpox than by guns. Smallpox and typhus among the French helped the British win the French-Indian War, and their soldiers in turn were significantly weakened by a malaria epidemic during the War of 1812. During westward expansion, pioneers spent much of their time burying one another, beset by malaria, typhus, diphtheria, pneumonia, yellow fever, smallpox, and cholera.
