Public Health Care

Public health refers to "the science and art of preventing disease, prolonging life and promoting human health through organized efforts and informed choices of society, organizations, public and private, communities and individuals. “It is worried about threats to health based on population health analysis. The population in question can be as small as a few of people, or as large as all the citizen of several continents. The dimensions of health can circumscribe "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity," as defined by the United Nations' World Health Organization. Public health combines the interdisciplinary approaches of epidemiology, biostatistics and health services. Environmental health, community health, behavioral health, health economics, public policy, mental health and occupational safety and health are other important subfields.
