Veterinary Epidemiology provides a comprehensive introduction to the principles and methods used to study the patterns, causes, and effects of diseases in animal populations. The book covers essential topics such as disease surveillance, outbreak investigation, study design, risk factor analysis, and statistical methods in epidemiology. It emphasizes the application of these concepts in real-world veterinary practice, helping readers understand how to prevent, control, and manage diseases in livestock, companion animals, and wildlife. Practical examples and case studies are included to illustrate key epidemiological methods and decision-making processes. The text also explores the role of epidemiology in public health, biosecurity, and policy development, highlighting the interconnectedness of animal health, human health, and the environment (One Health approach). By combining theory with applied techniques, the book equips students, researchers, and veterinary professionals with the knowledge to monitor disease trends, design effective control programs, and make evidence-based decisions in veterinary practice. The book is intended for veterinary students, researchers, and professionals involved in animal health, disease control, and public health. It is also valuable for epidemiologists, veterinary officers, and policymakers seeking a practical understanding of disease dynamics in animal populations.
