After World War II, world leaders realized that diseases and health crises could spread across borders and affect millions of people. During the United Nations Conference in 1945, countries proposed the creation of a global health organization.
In 1946, the WHO Constitution was adopted at the International Health Conference in New York. It officially came into force on 7 April 1948, marking the birth of the World Health Organization.
The first World Health Assembly was held in Geneva in 1948. Early priorities included:
- Malaria control
- Tuberculosis prevention
- Maternal and child health
- Nutrition improvement
- Sanitation and public health services
Since then, WHO has expanded its activities to cover virtually every aspect of global health.

International politics sometimes influence decision-making and cooperation among countries.
Emerging Diseases
New diseases and virus outbreaks require rapid global responses.
Health Inequalities
Many developing countries still struggle with limited healthcare resources.
Climate Change
Climate-related health risks such as heatwaves, floods, and disease spread create new challenges for global health systems.
Importance of WHO in the Modern World
WHO remains one of the most important international organizations because it:
