What is community health?
community health is The combination of sciences, skills and beliefs directed towards the maintenance and improvement of the health of all the people through collective or social actions. The programmes, services and institutions involved emphasize the prevention of disease and the health needs of the population as a whole. Community health activities change with changing technology and social values, but the goals remain the same.
