The World Health Organization (WHO) is a specialized agency of the United
Nations responsible for international public health.[1] The WHO Constitution, which
establishes the agency's governing structure and principles, states its main objective as
"the attainment by all peoples of the highest possible level of health".[2] It is
headquartered in Geneva, Switzerland, with six semi-autonomous regional offices and
150 field offices worldwide.
The WHO was established by constitution on 7 April 1948,[3] which is commemorated
as World Health Day.[4] The first meeting of the World Health Assembly (WHA), the
agency's governing body, took place on 24 July 1948. The WHO incorporated the
assets, personnel, and duties of the League of Nations' Health Organization and
the Office International d'Hygiène Publique, including the International Classification of
Diseases (ICD).[5] Its work began in earnest in 1951 following a significant infusion of
financial and technical resources.[6]
The WHO's broad mandate includes advocating for universal healthcare, monitoring
public health risks, coordinating responses to health emergencies, and promoting
human health and well being.[7] It provides technical assistance to countries, sets
international health standards and guidelines, and collects data on global health issues
through the World Health Survey. Its flagship publication, the World Health Report,
provides expert assessments of global health topics and health statistics on all
nations.[8] The WHO also serves as a forum for summits and discussions on health
issues.[1]
The WHO has played a leading role in several public health achievements, most notably
the eradication of smallpox, the near-eradication of polio, and the development of
an Ebola vaccine. Its current priorities include communicable diseases,
particularly HIV/AIDS, Ebola, COVID-19, malaria and tuberculosis; non-communicable
diseases such as heart disease and cancer; healthy diet, nutrition, and food
security; occupational health; and substance abuse. As p
