INTRODUCTION AND OBJECTIVES: Little is known regarding the relevance of racial/ethnic background to the risk for COVID-19 infection, particularly in Europe We evaluated the risk of COVID-19 among migrants from different areas of the world within the context of universal free access to medical care MATERIALS AND METHODS: We conducted a population-based cohort analysis of the cumulative incidence of PCR-confirmed COVID-19 among adult residents of Alcorcon (Spain) in the first wave of the disease up to April 25, 2020 RESULTS: The crude cumulative incidence among migrants (n=20419) was higher than among Spaniards (n=131599): 8 81 and 6 51 and per 1000 inhabitants, respectively (p < 001), but differed by region of origin As per a negative binomial regression adjusted for age and sex, relative risk (RR) for COVID-19 for individuals from Europe, Asia, or North Africa was not significantly different from Spaniards In contrast, a markedly increased risk was found in people from Sub-Saharan Africa (RR 3 66, 95% confidence interval (CI) 1 42-9 41, p = 007), the Caribbean (RR 6 35, 95% CI 3 83-10 55, p < 001), and Latin America (RR 6 92, 95% CI 4 49-10 67, p < 001) CONCLUSIONS: Migrants from Sub-Saharan Africa, the Caribbean, and Latin America exhibited increased risk for COVID-19 as compared to Spaniards or migrants from Europe, North Africa, or Asia Our data suggest ethnic background may play a role in risk for COVID-19 Migrants from some areas of the world may merit closer attention for both clinical and epidemiological reasons
