Public health is a broad field that touches several different medical disciplines such as epidemiology, public health informatics, health statistics, environmental protection (ecology), sociology, health promotion, disease prevention and organization of health care for nosological groups of the population. In Europe and the world today is developed a fairly extensive network of scientific and professional institutions engaged in research projects, studies, organization of scientific conferences and publishing scientific and professional articles from the field of public health. Their goal is to promote scientific advances in the field of public health through the exchange of experiences of public-health professionals, training, demonstration of appropriate research models, simulation and application in medical practice.
