From reviews of previous editions: "This book brings together the theoretical and practical information crucial to 'planning, organizing, analyzing, interpreting, and communicating surveillance information in the context of contemporary society and public health practice.' Nearly all the contributors are former or currently epidemiology specialists from the Centers for Disease Control and Prevention, and the 13 chapters of the book systematically cover the subject....The volume not only discusses system design and datainterpretation but also includes chapters on ethical and legal issues, computerized surveillance, and questions particular surveillance in developing countries." --American Journal of Public Health"Principles and Practice of Public Health Surveillance is a wonderful source of information on this underappreciated topic. It has two strengths in particular. First, it is by and large written by people who deal with public health surveillance systems and data on a daily basis and are intimately acquainted with their strengths and weaknesses. Second, the book is a one-stop source on public health surveillance and provides a single source reference onall aspects of surveillance in a straightforward, well-referenced, and readable manner. This is and will continue to be the single best source on public health surveillance. I recommend it to public healthpractitioners, public health students, and for researchers interested in further exploring this treasure trove of data."--American Journal of Epidemiology
