The result is a comprehensive introduction to modern epidemiology accessible to readers of all backgrounds and interests.Features in this new Foundations include:- Coverage of all the fundamentals of epidemiology, including measuring health status, characteristics of outbreaks, design and construct of epidemiologic studies- Exercises to check understanding- Chapters devoted to clinical epidemiology, fieldwork, evidence-based medicine, and evidence-based public health contextualize epidemiology and its place in medicine and societyDevoid of the digressions and inaccessibility that characterize many other introductory epidemiology texts, this new Foundations of Epidemiology will inform thinking and learning in the population sciences for decades to come. It is affordable, comprehensive, and enjoyable to read, one not likely to sit on the shelf collecting dust but to be consulted over time as one would when seeking guidance from a wise friend or mentor.
