Epidemiology is a basic science in preventive medicine that is also becoming increasingly important in clinical practice. The large number of epidemiology courses in universities illustrates the importance of the discipline in modern medicine. It is not only being taught to medical and public health students, but also to students of sociology, statistics and other disciplines. This book is designed for instructors; it points out the key elements in the teaching of modern epidemiology at different levels. It presents clear, practical information on implementing courses in epidemiology, on key methodological concepts, and on specific areas of disease- and exposure-oriented aspects of epidemiology.
