The 2030 health-related Sustainable Development Goals call on countries to end AIDS as a public health threat and also to achieve universal health coverage. The World Health Organization (WHO) promotes primary health care (PHC) as the key mechanism for achieving universal health coverage, and the PH ... C approach is also essential for ending AIDS and reaching other Sustainable Development Goal targets. The PHC approach is defined as a whole-of-society approach to health that aims to maximize the level and distribution of health and well-being through three components: (1) primary care and essential public health functions as the core of integrated health services; (2) multisectoral policy and action; and (3) empowered people and communities. This publication helps decision-makers to consider and optimize the synergies between existing and future assets and investments intended for both PHC and disease-specific responses, including HIV. Specifically, it aims to: • provide guidance to policy-makers, health system managers and programmatic leads from both PHC and HIV backgrounds regarding opportunities to jointly advance their respective efforts to strengthen PHC and end AIDS as a public health threat; and • provide a resource for all stakeholders who seek to contribute to strengthening PHC and ending AIDS as a public health threat in a synergistic manner, including people living with HIV, members of key and vulnerable populations, community and civil society representatives, people working in all areas of health systems, researchers, funders and private-sector decision-makers. more
