Abstract

© 2020 Elsevier España, S.L.U. Objectives: Given the scarcity of data regarding prevalence of various infectious diseases in Latin-American countries, our study aims to assess the burden of T. cruzi, S. stercoralis, HIV and viral hepatitis in Latin-American migrants, with a focus on Bolivian migrants. Methods: We performed a retrospective observational study of 565 screening evaluations in adults (≥18 years) carried out at our International Healthcare referral service in Barcelona. We reviewed structured clinical records and microbiological results of patients attended between February 2012 and April 2015. Results: The median age was 35 years and 74% were women. Of the population screened, 87% were of Bolivian origin. We found a 48% prevalence of T. cruzi, 16% of S. stercoralis, 0.2% of HIV, 0.2% HBV and 0.2% HCV. Conclusions: These results support the relevance of screening for T. cruzi and S. stercoralis in Bolivian migrants but challenge the pertinence of systematic screening for HBV in this population.
