Diseases have significantly shaped the course of the world's history. From the fourteenth-century plague to HIV/AIDS today, diseases have fundamentally altered the shape of society, politics, and culture. In a sweeping, thoughtful account, Twelve Diseases That Changed Our World considers the history of twelve important diseases: their impact, their consequences, their costs, and the lessons, learned. Examining porphyria, hemophilia, blight, tuberculosis, cholera, smallpox, bubonic plague, influenza, malaria, yellow fever, syphilis, and AIDS, this book not only covers the diseases' histories but also addresses public health responses and societal upheavals. Historical perspectives on these diseases will be indispensable for a better understanding of how we and our forbearers survived the onslaught of "plagues" and how we might avoid their devastating consequences in the future.
