Veterinary Epidemiology 4th Edition

This fully revised and expanded edition of »Veterinary Epidemiology« introduces readers to the field of veterinary epidemiology. The new edition also adds new chapters on the design of observational studies, validity in epidemiological studies, systematic reviews, and statistical modelling, to deliver more advanced material.
Features updates of all chapters to provide a current resource on the subject of veterinary epidemiology
Presents new chapters essential to the continued advancement of the field
Includes examples from companion animal, livestock, and avian medicine, as well as aquatic animal diseases
Focuses on the principles and concepts of epidemiology, surveillance, and diagnostic-test validation and performance
Includes access to a companion website providing multiple choice questions

»Veterinary Epidemiology« is an invaluable reference for veterinary general practitioners, government veterinarians, agricultural economists, and members of other disciplines interested in animal disease. It is also essential reading for epidemiology students at both the undergraduate and postgraduate levels.
MICHAEL THRUSFIELD is Professor of Veterinary Epidemiology at the Royal (Dick) School of Veterinary Studies in the University of Edinburgh in Edinburgh, UK.

ROBERT CHRISTLEY is Professor of Epidemiology and One Health at the Institute of Infection and Global Health and the Institute of Veterinary Science in the University of Liverpool in Liverpool, UK.
