Social determinants of health and migrant access to public healthcare in Brazil during the COVID-19 pandemic.
Article in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn recent decades, Brazil has emerged as a significant destination for migrants and refugees, contributing to a Global South-South migration trend. This trend is particularly notable for its influx from South and Central American countries, as well as African countries. Healthcare access in Brazil is universal through the Brazilian Health System (SUS). Although the existence of a social protection system is relevant, there are challenges to the law’s actual applicability in the country. Given the profound social and territorial inequalities existing in Brazil, the consequences of the pandemic have been particularly severe. The critical situations of social vulnerability have been intensified during the COVID-19 pandemic, posing a significant threat to the most impoverished populations, including international migrants. This article investigates how social determinants of health (SDH) shaped the experiences of international migrants in Brazil during the COVID-19 pandemic, particularly regarding access to the public health system.
methodsDrawing on qualitative, multi-sited fieldwork conducted in six Brazilian states between 2022 and 2023, the study analyzes in-depth interviews with 84 migrants from Venezuela, Haiti, Bolivia, Angola, Colombia, and Syria.
resultsThe research highlights significant vulnerabilities linked to employment status, housing, and racialized exclusion, while also documenting widespread access to Brazil’s Unified Health System (SUS) for COVID-19 testing, vaccination, and care. Despite systemic barriers—including xenophobia, documentation requirements, and language barriers—the findings underscore SUS’s role as a vital mechanism for inclusion.
conclusionThe study argues that an SDH framework is essential for understanding the intersectional inequalities affecting migrant health and for developing coordinated, rights-based, and transnational public health responses to global crises.
