The World Health Organization (WHO) is a specialized agency of the United Nations, responsible for international public health. It was established on April 7, 1948, with its headquarters in Geneva, Switzerland. The primary objective of the WHO is to ensure the highest possible level of health for all people. Its main functions include setting international health standards, coordinating responses to global health emergencies, and providing technical assistance to countries in need.
The WHO's governance structure includes the World Health Assembly, which is its decision-making body. All 194 member states participate in the assembly, which meets annually to set policies, approve budgets, and discuss pressing health issues. The organization is led by a Director-General, who is appointed by the World Health Assembly and serves a five-year term.
Throughout its history, the WHO has played a key role in combating diseases worldwide. Notable achievements include the eradication of smallpox in 1980, one of its most successful public health campaigns. The organization also coordinates global efforts to fight other infectious diseases, such as malaria, tuberculosis, and HIV/AIDS. It develops health guidelines and standards on a variety of topics, including nutrition, sanitation, and mental health.
The WHO leads global health initiatives, such as the International Health Regulations (IHR), which aim to prevent and respond to public health risks that could cross borders. It also monitors health data and trends to provide countries with evidence-based recommendations for improving public health systems. In recent years, the WHO has been instrumental in coordinating the global response to the COVID-19 pandemic, providing guidance on vaccine distribution, safety measures, and health system preparedness.
In addition to its work on infectious diseases, the WHO focuses on non-communicable diseases, mental health, and environmental health. It promotes healthier lifestyles through initiatives targeting tobacco control, alcohol abuse, and physical inactivity. The organization also works to address health inequities, ensuring that vulnerable populations have access to essential health services.
