The formation of WHO can be traced back to discussions held during the San Francisco Conference, when government representatives met between April and June 1945 to agree upon the Charter of the United Nations. Public health was not originally on the agenda, but it was raised as an important area of concern, resulting in its inclusion in Article 55 of the UN Charter as one of the areas for which international cooperation would be promoted; as well as in Article 57 where it is identified as a field in which a specialized UN agency would be established.[19]
