Global Health refers to health issues that transcend national boundaries, requiring international cooperation and comprehensive approaches. This field encompasses a variety of disciplines, including epidemiology, sociology, environmental health, economics, and policy studies.
Historical Context
The concept of global health emerged from earlier efforts in international health. Post-World War II, the establishment of the World Health Organization (WHO) in 1948 marked a significant milestone. Key events like the eradication of smallpox and the global response to HIV/AIDS in the late 20th century underscored the importance of international cooperation.
