The World Health Organization (WHO) is the United Nations specialized agency responsible for international public health. Its role is to promote health, expand universal health coverage, coordinate responses to health emergencies and support countries in improving their health systems.
WHO was founded in 1948 and is headquartered in Geneva, Switzerland.
WHO has a broad global health mandate.
Its work includes:
WHO describes its overall work as promoting health, keeping the world safe and serving vulnerable populations.
One of WHO's most important functions is international coordination.
Health problems do not stop at national borders. Infectious diseases can spread between countries, while issues such as antimicrobial resistance, climate change and health emergencies can require international cooperation.
WHO provides countries with scientific and technical guidance and helps coordinate international responses.
WHO plays a major role in health emergencies.
Its activities can include:
WHO says it provides global health leadership, mobilizes expertise and works with national authorities and frontline providers during health emergencies.
WHO is not a global hospital system.
Its primary role is to provide leadership, coordination, technical expertise, standards and support to countries and partners.
National governments remain responsible for operating their healthcare systems.
WHO develops international technical guidance and standards covering many areas of public health.
These can involve disease prevention, medicines, health emergencies, nutrition, vaccination, healthcare quality and other health issues.
WHO's role in setting global health standards is one of the reasons it is central to international public health cooperation.
WHO currently has 194 Member States, organized into six regions. Member States elect the Director-General, who leads the organization.
WHO employs professionals from many areas, including:
Therefore, WHO careers are not limited to medical doctors.
WHO is part of the broader UN system, but it is a separate specialized agency with a specific health mandate.
The UN itself has a much broader mandate covering international peace and security, development, human rights, humanitarian affairs and international law.
For people searching “What is the role of WHO?”, “What does WHO do?”, or “What is WHO responsible for?”, the answer is that WHO provides global health leadership, develops standards and guidance, supports countries and coordinates international health responses.
