The Role of Epidemiology and Public Health: Past, Present and Future; a Permanently Current Debate in the Life of the Communities

Abstract

The application of epidemiological knowledge is aimed at the control and prevention of diseases and the study of the health and disease process itself. This defines it as a science (with methodological rules, contributions to knowledge over time, hypothesis and analysis proposals with their valuations and rejections, and the generation of useful information for decision and action).
