As a basic introduction to epidemiology and public-health medicine, Lecture Notes on Epidemiology and Public Health Medicine covers the theory and practice of epidemiology, including study design, sources of information, medical demography, preventive medicine, public health, and the organization of medical care. The aim of this book is to place basic medical science into a global and clinical context. This edition has been fully revised with particular attention paid to the recent resurgence of some infectious diseases, the continuing developments in AIDS research, and the ongoing restructuring of health-care provision. This book will appeal to all medical students and practising doctors who want to make clinical decisions based on sound evidence.
