Collective health and regional integration in Latin America: An opportunity for building a new international health agenda.

From its origins, the Latin American Social Medicine and the Collective Health (LASM/CH) movements have focused on thinking about health from and for the region. After the implementation of neoliberal policies, social improvements and the geopolitical strengthening of the region became the roots of new regional integration projects in South America. The objective of this article is twofold. First, we explore the legacy of long-standing efforts in the region that address the social and political dimensions of health, associated with the LASM/CH movements and their influence on the contemporary regional health agenda. Second, we analyze the UNASUR Health policy, its role in the construction of a regional health agenda, and the principles of South-South cooperation it supports. In order to accomplish this, a qualitative analysis was conducted, involving primary and secondary data. Through UNASUR, a new framework of regional health integration and regional health diplomacy emerged in South America and a 'window of opportunity' opened for the ideas of Social Medicine and Collective Health to occupy a dominant place on the regional health agenda. It is possible to observe a confluence between the principles and values of these movements and those of the main constituent bases of UNASUR Health.
