Epidemiology, by award-winning educator and epidemiologist Leon Gordis, is a best-selling introduction to this complex science. Dr. Gordis leverages his vast experience teaching this subject in the classroom to introduce the basic principles and concepts of epidemiology in a clear, uniquely memorable way. He guides you from an explanation of the epidemiologic approach to disease and intervention, through the use of epidemiologic principles to identify the causes of disease, to a discussion of how epidemiology should be used to improve evaluation and public policy. It's your best choice for an accessible yet rich understanding of epidemiology! Overall, I think it is an excellent book for medical students and occupational medicine trainees and a useful revision and reference text for consultant occupational physicians one of the most clearly laid out and readable general epidemiology texts that I have ever seen .
