The Ecology Of Human Disease

This book summarizes current advances in our understanding of how infectious disease represents an ecological interaction between a pathogenic microorganism and the host species in which that microbe causes illness. The contributing authors explain that pathogenic microorganisms often also have broader ecological connections, which can include a natural environmental presence; possible transmission by vehicles such as air, water, and food; and interactions with other host species, including vectors for which the microbe either may or may not be pathogenic. This field of science has been dubbed disease ecology, and the chapters that examine it have been grouped into three sections. The first section introduces both the role of biological community interactions and the impact of biodiversity on infectious disease. In turn, the second section considers those diseases directly affecting humans, with a focus on waterborne and foodborne illnesses, while also examining the critical aspect of microbial biofilms. Lastly, the third section presents the ecology of infectious diseases from the perspective of their impact on mammalian livestock and wildlife as well as on humans. Given its breadth of coverage, the volume offers a valuable resource for microbial ecologists and biomedical scientists alike.

News headlines are forever reporting diseases that take huge tolls on humans, wildlife, domestic animals, and both cultivated and native plants worldwide. These diseases can also completely transform the ecosystems that feed us and provide us with other critical benefits, from flood control to water purification. And yet diseases sometimes serve to maintain the structure and function of the ecosystems on which humans depend. Gathering thirteen essays by forty leading experts who convened at the Cary Conference at the Institute of Ecosystem Studies in 2005, this book develops an integrated framework for understanding where these diseases come from, what ecological factors influence their impacts, and how they in turn influence ecosystem dynamics. It marks the first comprehensive and in-depth exploration of the rich and complex linkages between ecology and disease, and provides conceptual underpinnings to understand and ameliorate epidemics. It also sheds light on the roles that diseases play in ecosystems, bringing vital new insights to landscape management issues in particular. While the ecological context is a key piece of the puzzle, effective control and understanding of diseases requires the interaction of professionals in medicine, epidemiology, veterinary medicine, forestry, agriculture, and ecology. The essential resource on the subject, Infectious Disease Ecology seeks to bridge these fields with an ecological approach that focuses on systems thinking and complex interactions.

First published in 1998, this book contributes to our understanding of emergent and resurgent infectious diseases and health ecology in developing areas through detailed spatial and temporal analysis of recent cholera and bacillary dysentery epidemics in Mozambique. The book examines the influence of environmental, demographic and socio-economic changes on the nature and context of cholera and bacillary dysentery. It provides a detailed background to the two diseases based on their ecology and contemporary status in human communities together with analysis of extensive primary field data centered on three key urban areas in central Mozambique. Influences are weighed up against factors relating to the individual ecologies of the different pathogens, primary subsistence, and the impacts of Mozambique's history of conflict and development policies on human vulnerability. The extensive case study material is used to provide clear indications of appropriate ways forward in the field of environmental health management.

Social Ecology of Infectious Diseases explores how human activities enable microbes to disseminate and evolve, thereby creating favorable conditions for the diverse manifestations of communicable diseases. Today, infectious and parasitic diseases cause about one-third of deaths and are the second leading cause of morbidity and mortality. The speed that changes in human behavior can produce epidemics is well illustrated by AIDS, but this is only one of numerous microbial threats whose severity and spread are determined by human behaviors. In this book, forty experts in the fields of infectious diseases, the life sciences and public health explore how demography, geography, migration, travel, environmental change, natural disaster, sexual behavior, drug use, food production and distribution, medical technology, training and preparedness, as well as governance, human conflict and social dislocation influence current and likely future epidemics. Provides essential understanding of current and future epidemics Presents a crossover perspective for disciplines in the medical and social sciences and public policy, including public health, infectious diseases, population science, epidemiology, microbiology, food safety, defense preparedness and humanitarian relief Creates a new perspective on ecology based on the interaction of microbes and human activities

Introduces readers to key case studies that illustrate how theory and data can be integrated to understand wildlife disease ecology.

This book provides descriptions of public health problems, including historical background and ecological perspectives.
