Primary health care is a whole society approach for health to ensure better health and wellbeing by focusing on population’s needs and timely response to those needs including provision of services from prevention, protection up to treatment rehabilitation and palliative care.
Primary health care has been at the heart of Cambodia's health system reform since 1995. Operational district health systems, which include health centers and referral hospitals that provide basic geographical and demographic services, have played an important role in strengthening health infrastructure, providing efficient, equitable services that can better meet the needs of the population and has contributed to significantly reducing maternal, and child mortality and infant under five years and some infectious diseases such as AIDS, malaria and tuberculosis.
