Epidemiology is the basic science for studying causality in humans. Causal research concerns both the numerous diseases of unknown etiology and the study of specific epidemics, as well as therapeutic medicine, since treatment essentially determines better prognosis. This book focuses on general and clinical epidemiology, without reference to specific epidemiology of specific infectious or non-infectious diseases.

Medical knowledge is being revised and enriched at a rapid pace. The continuous updating of doctors and responsible health officials and their critical assessment of published findings becomes imperative. Knowledge of general and clinical epidemiology is therefore necessary, 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 being a useful aid for students and young scientists in medicine and other sciences serving the protection and restoration of human health.
