The World Health Organization, the United Nations specialized agency for health, was established on 7 April 1948. WHO's objective, as set out in its Constitution, is the attainment by all peoples of the highest possible level of health. Health is defined in WHO's Constitution as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.

WHO is governed by 192 Member States through the World Health Assembly. The Health Assembly is composed of representatives from WHO's Member States. The main tasks of the World Health Assembly are to approve the WHO programme and the budget for the following biennium and to decide major policy questions.

The Secretariat is headed by the Director-General, who is nominated by the Executive Board and elected by Member States for a period of five years. Dr LEE Jong-wook took office as Director-General of the World Health Organization on 21 July 2003.

WHO's Secretariat is staffed by health professionals, other experts and support staff working at headquarters in Geneva, in the six regional offices and in countries. WHO's regional offices are:

• Regional Office for Africa -- located in Brazzaville, Republic of Congo

• Regional Office for the Americas/Pan-American Health Organization -located in Washington D.C., USA
