Key points
- Primary health care is a whole-of-society approach to health: it covers promotion, prevention, treatment, rehabilitation and palliative care, close to where people live.
- It has three parts: primary care and essential public health functions; multisectoral policy and action; and empowered people and communities.
- Primary health care is not the same as primary care. Primary care is the first-contact service level; primary health care is the wider approach that contains it.
- WHO calls primary health care the cornerstone of universal health coverage, and the foundation of an effective health system.
- WHO estimates that scaling up primary health care in low- and middle-income countries could save 60 million lives and add 3.7 years to life expectancy by 2030.
Direct answer: Primary health care is the first level of contact people have with a health system, and the approach that organises health around communities rather than hospitals. The World Health Organization (WHO) describes it as a whole-of-society approach: health promotion, disease prevention, treatment, rehabilitation and palliative care, delivered as close as possible to where people live and work. It is the foundation of an effective health system and the cornerstone of universal health coverage — not a synonym for a GP visit, and not a service for poor countries only. Every country has primary health care; what differs is how strong it is.
What primary health care means
The idea was first set out in the Declaration of Alma-Ata in 1978, when WHO and UNICEF defined primary health care as essential health care, based on practical, scientifically sound and socially acceptable methods, made universally accessible to individuals and families in the community, at a cost the community and country can afford. The Declaration of Astana, adopted at the Global Conference on Primary Health Care in October 2018, renewed that commitment forty years on and restated primary health care as the path to universal health coverage and the health-related Sustainable Development Goals. The Astana Declaration was endorsed by the World Health Assembly in May 2019.
WHO’s definition has three inter-related parts, and all three matter. A system that has only the first — clinics — is primary care, not primary health care. The three parts are set out in the next section.
The three parts of primary health care
First, primary care and essential public health functions as the core of integrated health services. This is the service level most people meet: the GP or family doctor, the community nurse, the midwife, the pharmacist, the community health worker — plus the public health functions that sit behind them, such as immunisation, screening, surveillance and health protection. Care is meant to be continuous across a person’s life, not a series of one-off visits.
Second, multisectoral policy and action to address the wider determinants of health. Health is shaped outside clinics — by housing, education, income, water, food and work. Primary health care therefore involves action across sectors, not only inside the health ministry. This is the same ground as the social determinants of health, explained in the guide on that topic.
Third, empowered people and communities. People and communities are not passive recipients of care: they take part in shaping services, and they are supported to look after their own health. Community participation was a founding principle at Alma-Ata and remains one at Astana.
Primary health care is not the same as primary care
The two phrases are often used as if they meant the same thing. They do not. Primary care is a level of service: the first-contact care a person turns to — a GP surgery, a family medicine clinic, a community health centre. Primary health care is the wider approach that contains primary care and adds the public health functions, the cross-sector action and the community participation described above. A country can have plenty of primary-care clinics and still have weak primary health care, if those clinics are disconnected from prevention, from other sectors and from the communities they serve.
A related confusion is with family medicine. Family medicine is a medical specialty: doctors trained to care for people of all ages, across most conditions. Primary care is a level of service, delivered by family doctors and by many others — nurses, midwives, pharmacists, community health workers. Primary health care is bigger than both: it is the approach that organises all of them around communities.
Primary health care and universal health coverage
WHO calls primary health care the cornerstone of universal health coverage. The reasoning is practical: most health needs can be met, or prevented, at the primary level, and meeting them there costs less than meeting them in hospital. When primary care is weak, people arrive at hospitals later and sicker, and households pay more. WHO estimates that scaling up primary health care in low- and middle-income countries could save 60 million lives and add 3.7 years to life expectancy by 2030, and that primary health care could deliver 75% of the projected health gains linked to the Sustainable Development Goals. Both figures are WHO estimates, not measured outcomes.
That is also why primary health care is the route to universal health coverage rather than a rival to it. Universal health coverage means everyone getting the quality services they need without financial hardship; primary health care is the way services are organised so that coverage is real in practice, not only on paper.

Primary health care around the world
The shape of primary health care differs by country, because the first point of contact differs. In the United Kingdom, the GP is the first point of contact and the gatekeeper to specialist care. In Canada, family physicians play the same role inside provincial plans. In many low- and middle-income countries, community health workers and nurses carry much of the first-contact load. In Japan, patients can choose any provider without a referral, so first contact is less structured. What the strong systems share is not one structure but three habits: first contact that is easy to reach, care that continues over time with the same team, and services that connect prevention with treatment instead of keeping them apart. The country profiles in this site show how six systems organise that first contact differently.
Frequently asked questions
Is primary health care the same as primary care?
No. Primary care is the first-contact level of services — the GP, family doctor or community clinic a person turns to first. Primary health care is the wider approach: primary care plus essential public health functions, action across sectors, and empowered communities.
Is primary care the same as family medicine?
No. Family medicine is a medical specialty — doctors trained to care for people of all ages. Primary care is a level of service, delivered by family doctors and by many other workers, including nurses, midwives and community health workers.
Why does primary health care matter for universal health coverage?
Because most health needs are met, or prevented, at the primary level. WHO calls primary health care the cornerstone of universal health coverage: without strong primary care, hospitals carry a load they cannot carry alone, and people pay more, later, for care that could have come earlier.
