Malaria y determinantes sociales de la salud: un nuevo marco heurístico desde la medicina social latinoamericana

Abstract

Traditionally, malaria research and study have followed the positivist scientific paradigm and its biomedical conception of disease. From this perspective, diverse control actions and strategies have been designed. However, despite a century of scientific experience and the depth and thoroughness achieved in the knowledge of malaria, this has not been translated into a constant and progressive decrease of its epidemiological burden. This essay argues for the need for a change in malaria conception, reconfiguring it as a process of biological and social character, where the geno-phenotypical possibilities of the host-parasite relationship and of the diseases clinical expression are articulated with the historic and social dynamics of the spaces in which they occur. In addition, it proposes rethinking the epidemiological research of this entity on the basis of the visualization of the dynamic, heterogeneous, dialectic and complex character of biosocial organizations that constitute the reality of malaria (from the social structure to the genetic and phenotypic level of parasite individuals, vectors and humans). To achieve this, it is suggested that: 1) the Latin American perspective on the social determinants of health be adopted; 2) new analytical categories (for instance, malaria social territory) and new investigation tools (matrices of critical processes of social determination) be incorporated, and 3) the conventional epidemiological categories of infectious diseases such as the transmission and infectiousness be reinterpreted.
