Abstract
This paper presents a conceptual approach to the category of intersectionality, in the quest for new meanings for better understanding and addresing the issue of inequalities related to mother-to-child HIV transmission. To this end, some of the most outstanding theoretical development of the intersectional debate are initially shown. Subsequently, the tensions that have emerged from different currents of feminist critical epistemology with respect to its conceptualization and methodological operationalization will be addressed. Next, several works are presented that show the power of intersectional analysis in the empirical study of health inequities related to HIV. Finally, it discusses the importance of including intersectionality as an analytical framework in the reflection of the work of public health in the transformation of inequalities in the determinants of health and health outcomes, as well as providing key elements that help to overcome discrimination. It also suggests tools for advocacy work and the elaboration of public health policies in order to build a culture of human rights as a fundamental axis of the political exercise and of public health praxis itself.
