Direct answer (HL only): The World Health Organization (WHO) coordinates international responses to health challenges, establishes standards, provides technical support and monitors health trends. However, it cannot compel sovereign states to follow its recommendations.
How the WHO Influences Global Health
The WHO is a specialized United Nations agency and an important institution of global governance. It responds to health problems that cross borders and therefore require cooperation among states, international organizations and non-state actors.
| Role | How it operates | Contemporary example |
|---|---|---|
| Setting standards | Produces evidence-based guidelines and evaluates medicines, vaccines and public-health practices | In 2023, the WHO recommended the R21/Matrix-M malaria vaccine for children in malaria-endemic areas. |
| Coordinating emergencies | Collects information, assesses risks and coordinates international action under the International Health Regulations | On 14 August 2024, the WHO declared the mpox outbreak centred in the Democratic Republic of the Congo a public health emergency of international concern. |
| Supporting states | Provides expertise, surveillance assistance, training and emergency resources | Its 2024 mpox response plan supported laboratory capacity, vaccination, surveillance and clinical care. |
| Facilitating cooperation | Provides a forum in which member states negotiate shared rules | The World Health Assembly adopted the WHO Pandemic Agreement on 20 May 2025 to strengthen pandemic preparedness and equitable access to health products. |
The WHO demonstrates interdependence because infectious diseases cannot be contained effectively by one state acting alone. Its influence rests mainly on expertise, coordination and soft power, while its legitimacy depends on scientific credibility and support from member states.
A common misconception is that the WHO controls national health policy. It does not: remains with states, which decide whether and how to implement WHO guidance. This limits enforcement, especially when governments withhold information, resources or cooperation.
