RESUMO
Doctors have played an important role in the development of health institutions in Latin America. However, they are not the only profession that has had a voice in these matters. There are also other factors influencing the development of ministries of health. This issue has gone unnoticed in the literature. This article suggests that it is possible to identify two distinct trends in the creation of health ministries in Latin America. The first, of an early nature, was seen principally in Central America and the Caribbean in countries dependent on or under the influence of the United States which, from the 1880s, promoted health Pan-Americanism. The second trend, which became apparent from 1924, was characterised by the emergence of ministries in a context of institutional breakdown and the appearance of new actors (military or populist leaders). This second trend was first seen in Chile in 1924. This article analyses the creation of the Ministerio de Higiene, Asistencia y Previsión Social (Ministry of Hygiene, Assistance and Social Security) in Chile in 1924 and its subsequent development through to 1931. The analysis looks at the health measures adopted, the context in which this occurred and the debates triggered by the ministry's process of institutional development, based on parliamentary discussions, presidential speeches, official statistics, legislation, documents prepared by key actors and the press of the time.
