Disease is an ever-present threat faced by all human societies. Today, this concept has become an influential area of study known as the global burden of disease, which encompasses contemporary health concerns such as the economic costs of disease, the societal impact of illness in developing nations, and infectious diseases resulting from lifestyle exposures. Before we can ease this global burden, it is essential to establish an accurate view of the current status of human health and disease around the world.Addressing key areas that reflect our understanding of disease, The Changing Face of Disease: Implications for Society explores the evolution of disease, the implications for human societies, its ecology, and the current human response. This volume aims to broaden our view of disease at the dawn of the 21st century through topics such as epidemiological transition, mathematical modeling of disease evolution, parasitic disease, urban pollution and illness, and under-nutrition and obesity. Contributions to the text reflect the authors' diverse perspectives and studies on human population biology, biological anthropology, and biomedical and public health issues. This authoritative volume traces the evolution of modern disease and explores contemporary health challenges resulting from genetic, environmental, economic, and lifestyle factors. Through many levels of analysis, it provides a clear picture of the present state of health and disease and reminds us of the global burdens that have yet to be remedied.
