Public Health and Epidemiology
Public health is concerned with protecting the health of entire populations. Epidemiology is the study and analysis of the cause, effect, and pattern of diseases. It is the key discipline of public health and identifies risk factors for disease and objectives for preventive health care. The main part of Epidemiology is to gain a new understanding of the correlation of genetic and environmental factors affecting human health, providing the scientific basis for translation of this knowledge to global health. It is applied to cover the explanation of epidemic diseases and health-related conditions like obesity and high blood pressure.
