The main purpose of the World Health Organization (WHO) is to direct and coordinate international public health efforts. Established in 1948 as a specialized agency of the United Nations, WHO aims to promote health, keep the world safe, and serve vulnerable populations. It provides leadership on global health matters, shapes the research agenda, and sets norms and standards. Additionally, the organization monitors health trends and provides technical assistance to countries to strengthen health systems. WHO’s initiatives address various health challenges, including pandemics, noncommunicable diseases, and health-related issues to improve the well-being of people globally.
