The World Health Organization is a specific group within the United Nations that directs and pulls together international health work. WHO currently has 192 member states. In 1945 the United Nations conference held in San Francisco approved a proposal to create a new international health organization. Other health organizations had existed before WHO, but were not as wide in scope as the United Nations. The constitution for the World Health Organization was created in 1945, and was enacted on April 7, 1948.      WHO’s mission stated in the Constitution is “attainment by all people of the highest possible level of health.” The definition of health for WHO: “Is a state of complete physical, mental, and social well-being and not merely an absence of disease or infirmity.”      The functions of WHO are: Give worldwide teaching in the field of health Set standards for health Create peace with governments in building national health programs Develop and transfer appropriate technology, information, and standards about health      Currently WHO is dedicated to eliminating polio and leprosy, among other diseases.
