World Health Organization
United Nations agency concerned with international public health
The World Health Organization (WHO) is a specialized agency of the United Nations (UN) which coordinates responses to international public health issues and emergencies. It is headquartered in Geneva, Switzerland, and has six regional offices and 150 field offices worldwide. Only sovereign states are eligible to join, and it is the largest intergovernmental health organization at the international level.
The WHO's stated purpose is to achieve the highest possible level of health for all the world's people, defining health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." The main functions of the World Health Organization include promoting the control of epidemic and endemic diseases; providing and improving the teaching and training in public health, the medical treatment of disease, and related matters; and promoting the establishment of international standards for biological products.
The WHO was established on 7 April 1948, and formally began its work on 1 September 1948. It incorporated the assets, personnel, and duties of the League of Nations' Health Organization and the Paris-based Office International d'Hygiène Publique, including the International Classification of Diseases (ICD). The agency's work began in earnest in 1951 after a significant infusion of financial and technical resources.
The WHO's official mandate is to promote health and safety while helping the vulnerable worldwide. It provides technical assistance to countries, sets international health standards, collects data on global health issues, and serves as a forum for scientific or policy discussions related to health. Its official publication, the World Health Report, provides assessments of worldwide health topics.
Begin with the source’s own compact description: “World Health Organization” is united Nations agency concerned with international public health. The dossier treats that line as a proposition to test through World, Health and Organization, not as a finished interpretation.
Why this record matters
The phrase “united Nations agency concerned with international public health” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q7817. VIAF identifies the subject as 135618969. The Library of Congress control number is n79059041. Authority coordinates are 46.234, 6.134. 5 of 12 selected statements include explicit references; 8 carry qualifiers and 1 use preferred rank. The first chronological checks are 1948 and 1951.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
