List of specialized agencies of the United Nations The World Health Organization (WHO) acts as a coordinating authority on international public health and deals with health and sanitation and diseases and sends medical teams to help combat epidemics. Established on 7 April 1948, the agency inherited the mandate and resources of its predecessor, the Health Organization, which had been an agency of the League of Nations. It was established in April 7, 1948 when 26 members of the United Nations ratified its Constitution. April 7 is celebrated as the World Health Day every year. The WHO is governed by 194 Member States through the World Health Assembly. Its headquarters are at Geneva in Switzerland.
