Introduction
The World Health Organization (WHO) is a specialized agency of the United Nations (UN) responsible for directing and coordinating international public health efforts. Established in 1948, it leads global action to improve health systems, respond to emergencies, and promote well-being for all people worldwide.
WHO defines health as “a state of complete physical, mental and social well-being, not merely the absence of disease or infirmity.”
Today, WHO works with 194 Member States across six regions, supporting countries to achieve universal health coverage, disease prevention, and emergency preparedness.
History and Background
The WHO was founded on 7 April 1948, following the adoption of its Constitution by UN member countries.
Key historical milestones:
- Pre-1948 origins: Built on earlier international health bodies such as the International Office of Public Health
- 1948: WHO officially established as a UN specialized agency
- 20th century: Major achievements in global disease control, including smallpox eradication
- 1980: Smallpox officially declared eradicated globally through WHO-led vaccination campaigns
- 2020: WHO declared COVID-19 a global pandemic and coordinated international response
WHO has since become the central institution for global disease surveillance, health standards, and emergency coordination.
Mission and Purpose
The mission of WHO is to ensure that all people can attain the highest possible level of health.
Core objectives:
- Promote universal health coverage
- Coordinate responses to health emergencies and pandemics
- Improve maternal, child, and elderly health
- Combat infectious diseases such as HIV/AIDS, malaria, and tuberculosis
- Address non-communicable diseases (NCDs) like cancer and diabetes
- Strengthen health systems globally
WHO’s work is guided by its constitutional principle of health equity and human rights.
