The mission of the World Health Organization (WHO) is to promote health, keep the world safe and serve vulnerable populations. Its constitutional objective is "the attainment by all peoples of the highest possible level of health." WHO is the United Nations specialized agency for international public health, working with countries and partners to improve health and well-being. (WHO Constitution)
WHO's mission is grounded in the principle that health is a fundamental human right.
The organization works to ensure that people can access the health services they need, that countries are better prepared for health emergencies and that populations have opportunities to live healthier lives.
Its work includes:
Expanding universal health coverage.
Preventing and controlling diseases.
Coordinating responses to health emergencies.
Supporting stronger health systems.
Developing public-health standards and guidance.
Improving access to essential medicines and health technologies.
Addressing mental health and noncommunicable diseases.
Promoting healthier environments.
WHO works with governments, health professionals, researchers, civil society and other international organizations to advance these priorities.
WHO's constitutional objective provides the clearest official foundation for its vision: the highest attainable standard of health for all people.
In practical terms, this means a world where people can achieve better health regardless of where they live, their income or their circumstances.
It also means that countries should have stronger systems to prevent illness, provide essential care and respond to public-health emergencies.
The exact wording of WHO's strategic vision can vary between strategy documents and planning periods, so it is best to distinguish the organization's enduring constitutional objective from the specific goals of a particular strategic plan.
WHO describes its work around three broad objectives:
WHO supports policies and programmes that prevent disease and help people live healthier lives. This includes work on nutrition, physical activity, environmental health, mental health and disease prevention.
WHO helps countries prepare for, detect and respond to health emergencies, including infectious disease outbreaks and other public-health threats.
WHO works to improve health outcomes for populations facing barriers to healthcare, including people affected by poverty, conflict, displacement and unequal access to essential services.
These priorities are closely connected. Health systems need to be accessible, resilient and able to respond to both everyday healthcare needs and major emergencies.
WHO develops technical guidance, coordinates international cooperation, provides policy advice, collects health data and supports countries in strengthening their health systems.
It also works with partners on vaccination, disease prevention, emergency preparedness, access to medicines and many other public-health priorities.
WHO does not replace national health ministries or operate as a worldwide hospital system. Its role is to support and coordinate international public-health action.
WHO's mission is to promote health, protect people from health emergencies and serve vulnerable populations. Its enduring constitutional objective is to help all people attain the highest possible level of health. Through international cooperation, technical guidance and support for national health systems, WHO works toward a healthier and safer world.
