The basis of public health is to analyze the health status of people and the threat to health. The definition of public can range from a small village to a continent, while the definition of health can range from physical health, mental health and social happiness.
Public health is interdisciplinary. For example, epidemiology, biostatistics and health services are closely related to public health. In addition, public health also involves environmental health, behavioral health, health economics, public policy, occupational safety and other fields.
