Epidemiology is the fundamental science for studying causation in humans. Causal research pertains to both numerous diseases of unknown origin and the study of specific epidemics, as well as therapeutic medicine, since treatment essentially constitutes the cause of better prognosis.

This book focuses on general and clinical epidemiology, without reference to issues of special epidemiology of specific infectious or non-infectious diseases. Medical knowledge is being revised and enriched at a rapid pace. Continuous updating of physicians and health officials and their critical assessment of published findings becomes imperative.

Knowledge of general and clinical epidemiology is therefore essential, as more than half of the articles published in major international medical journals are based on epidemiological principles and methods.

The second edition of the book General and Clinical Epidemiology was written with the aim of serving as a useful aid for students and young professionals in medicine and other sciences dedicated to the protection and restoration of human health.
