Primary health care (PHC) refers to essential health care services provided at the local community level, including health promotion, disease prevention, and treatment of common illnesses. PHC aims to make health care accessible, affordable, and equitable for all through a community-based approach. Key principles of PHC include community participation, intersectoral coordination between health and other sectors, and making available basic services such as maternal/child care, immunization, treatment of common diseases, and ensuring access to safe water and nutrition. PHC forms the first level of contact with the larger health system and aims to deliver fundamental health care that is close to where people live and work.
