A dimensão transnacional da hanseníase: Leste de Minas e os Estados Unidos

Abstract

This study aimed to analyze the relationship between territory, migration, and health, investigating how disease circulation occurs in the context of Eastern Minas Gerais, a region historically marked by international migratory flows, especially to the United States. The research was conducted through a case study using a qualitative approach and documentary analysis of clinical and laboratory data from a participant residing in an area endemic for leprosy. Sociodemographic information, health history, results of serological and molecular tests, and records of clinical evaluations at two distinct stages were examined. The results were positive for the bacterium Mycobacterium leprae by qPCR and serology with the anti- LID-1 reagent, indicating possible subclinical infection, even in the absence of clinical alterations. The discussion articulated the empirical findings in relation to the literature on transnational disease circulation, social vulnerability, and territorial determinants of health, highlighting that regions with high population mobility exhibit greater epidemiological interdependence between origin and destination regions. It is concluded that the movement of people between historically connected territories can favor the silent spread of neglected diseases, requiring integrated surveillance and a transnational approach to public health.
