Public Health

A sub-discipline of Health Professional Education

The science and art of avoiding disease, extending life, and increasing quality of life via organized efforts and educated decisions of society, organizations (public and private), communities, and individuals are incorporated within the larger discipline of 'public health'.

The foundation of public health is the analysis of a population's determinants of health and the challenges it faces. The public can be as tiny as a few individuals or as vast as a village or a metropolis; in the case of a pandemic, it could span multiple continents. The term 'health' refers to a person's physical, mental, and social well-being.

The field of public health is multidisciplinary. Epidemiology, biostatistics, social sciences, and healthcare management, for example, are all relevant. Environmental health, community health, behavioral health, health economics, public policy, mental health, health education, health politics, occupational safety, disability, dental public health, gender issues in health, and sexual and reproductive health are some of the other major subfields. Public health is a component of a country's entire healthcare system, along with primary, secondary, and tertiary care.
