The World Health Organization (WHO) was established in 1948 as the United Nations specialized agency responsible for international public health. WHO works to promote health, protect populations from health emergencies, and improve access to essential health services worldwide.

WHO serves as a central coordinating body for global health by setting international standards, providing technical assistance to countries, monitoring health trends, and supporting responses to disease outbreaks and other public health emergencies. Its work also includes strengthening health systems, expanding universal health coverage, preventing disease, and addressing disparities in access to health care.

As health challenges increasingly cross national borders, WHO relies on international cooperation and science-based policy to coordinate effective responses. Through collaboration among governments, health professionals, and international partners, WHO strives to ensure that all people, regardless of circumstance, have the opportunity to achieve the highest possible level of health as a fundamental right.
