Basic Epidemiology

This is an authorised reprint of a World Health Organization publication. This book gives an introduction to the basic principles and methods of epidemiology. It begins with causes of diseases and how they can be prevented by modification of environmental factors, which, in turn, can lead to promotion of better health in the community. This is substantiated by numerous examples from scientific literature. Further, individual chapters deal with the application of epidemiology to communicable diseases, environmental and occupational health and health care planning for medical students, postgraduate students of community health and other health professionals doing such courses.
