Differential Risk for COVID-19 in the First Wave of the Disease (February-April 2020) Among Migrants From Several Areas of the World Living in Alcorcón, Spain: A Population-Based Cohort Study

The study conducted in Alcorcón, Spain, during the first wave of COVID-19 (February-April 2020) found that the cumulative incidence of PCR-confirmed COVID-19 was higher among migrants (n=20,419) compared to Spaniards (n=131,599), with rates of 8.81 and 6.51 per 1,000 inhabitants, respectively. The risk varied by region of origin; migrants from Sub-Saharan Africa, the Caribbean, and Latin America had significantly higher relative risks (RR 3.66, 6.35, and 6.92, respectively) compared to Spaniards, while those from Europe, Asia, or Northern Africa did not show significant differences. The findings suggested that migrants from certain regions might require more focused clinical and epidemiological attention.
