6 Preface Most of the textbooks for epidemiology and veterinary medicine mentioned surveillance and survey as approaches to monitor and subsequently prevent the spread of diseases. Most of these books, however, assume that readers and users of epidemiology have the knowledge to excuse scientifically based plan for surveillance program. There are several methodological issues that need to be considered before such planning. Although some of these issues have been addressed in some of these textbooks, their relevant values to surveillance or monitoring were not included. Furthermore, most of these excellent books in epidemiology and preventive medicine have ignored the potential implementers and users of surveillance programs specifically, government, international organizations, and public health agencies. Such users may require different ways to present information with more instruction on how to do it and fewer academic concepts. This book attempts to satisfy the requirements for an effective and scientifically sound surveillance for animal diseases or other health issues. Both concepts and examples are given for several of the approaches to such surveillance systems. The intention is to avoid in-depth academic elaboration of specific issues, as such elaboration is found in other classical textbooks. Mo Salman vii

7 Acknowledgments This book has been influenced by many people. I wish to gratefully acknowledge the dedication of the contributors to this book. They are the essential nucleus for this book without their input, this book would not have been published. My special thanks to Ian Gardner, who has contributed several chapters of this book. Ian was the power that generated this book as a friend and colleague, his support was valuable for the completion of this book. His persistence and encouragement for moving ahead with the project were the main reasons for its existence. Several of my teachers, colleagues, and graduate students have contributed mentally to this book. Without them I will not be able to challenge myself for issues to be addressed in this book. My thanks to all of those who challenged me and accepted my extreme ideas. The research team that worked on the United States Animal Disease Surveillance System (what is currently known as Animal Health Monitoring System) in the early 1980s has contributed to several of the ideas for this book. My thanks and appreciations go to the team members for their input. Finally, my sincere appreciation goes to my wife Carole Salman, who has been so patient with me in accepting long hours of work. She accepts me as a man attached to veterinary epidemiology. Mo Salman viii
