The science and discipline of epidemiological applications and research are continuously expanding. This is not only from the perspective of theoretical suppositions but extends to the application of epidemiological principles in real life situations. It subtends an ever widening reach across multiple disciplines and arenas of community-based inquiry with respect to its importance to modern day societal interests. This book brilliantly encapsulates the swiftly evolving and complex field of public health epidemiology from both its theoretical foundations to its practical applications.

The book begins by defining in a clear, concise manner the theoretical underpinnings of epidemiology. It then goes on to explain, from a historical perspective, how the field of epidemiology evolved over time. The discussion includes an elucidation of the fundamental concepts of causation and their relationship to natural phenomena. A full review of its uses in the fields of disease prevention, disease outbreak investigation, cluster analysis, and surveillance techniques then follows. Several chapters are devoted to epidemiologic study designs and experimental studies. These include analytic ecological and cross-sectional studies, prospective and retrospective cohort studies, and case-control studies.

The book goes further, to firmly establish how the morbidity and mortality measurements are utilized in the field of epidemiology as well as the comparison of rates. The practical applications are then explained through the lens of association and causation theory. Screening and the detection of diseases are explained with a full discussion of their practical implications for the population being serviced. The analysis of intervention outcomes is then addressed from the standpoint of accuracy of the intervention utilized to reach a desired outcome. The book ends with a contemplation of what the future holds for the discipline of epidemiology.
