Epidemiology 7th Edition

Epidemiology, now in its seventh edition, remains the standard introductory textbook for students and professionals seeking a comprehensive foundation in epidemiologic methods and principles. Leon Gordis guides readers through the core concepts that define modern public health practice - from disease causation and measurement to study design and evidence evaluation. The text balances theoretical frameworks with real-world application, making complex statistical and methodological concepts accessible without sacrificing rigor.

This edition reflects current epidemiologic practice and incorporates contemporary examples of disease surveillance, outbreak investigation, and population health assessment. Gordis's approach emphasizes the logic underlying epidemiologic reasoning, helping readers understand not just what methods exist, but why they matter for answering critical public health questions. The book covers descriptive and analytical studies, screening and diagnostic testing, and the broader context of disease prevention and health policy.

Ideal for undergraduate and graduate students in public health, medicine, nursing, and related fields, this text serves equally well as a reference for practicing epidemiologists and health professionals. Clear diagrams, worked examples, and chapter summaries reinforce key concepts without oversimplifying the discipline.
