The World Health Organisation is a specialist institution in the United Nations for health, and was founded on 7 April 1948. As stipulated in its Constitution, the aim of the World Health Organisation is to bring the highest level of health possible to all people. Health is defined in this same document as a state of full physical, mental, and social well-being, and is not the absence of disease or infirmity alone.
The WHO is run by the 192 Member States that meet at the World Health Assembly. This assembly is made up of delegates representing Member States. Its main roles are to approve the WHO programme and budget for the next biennial accounting period and decide on the main political directions of the Organisation.
