The document discusses primary health care (PHC). It defines health as a state of complete physical, mental and social well-being, not just the absence of disease. PHC is defined by the WHO as essential health care made universally accessible through community participation and affordable costs.
The key principles of PHC include addressing main health problems through promotion, prevention, treatment and rehabilitation. Its essential components are environmental sanitation, disease control, immunization, health education, maternal and child care, nutrition, medical care, and treatment of local diseases. PHC relies on health workers like nurses and community workers to form a team and respond to community needs.
