Epidemiological trends of HIV‐1 infection in blood donors from Catalonia, Spain (2005‐2014)

Human immunodeficiency virus 1 (HIV‐1) subtype B is predominant in Spain. However, the recent arrival of immigrant populations has increased the prevalence of non‐B subtypes and circulating recombinant forms. The objective of this study was to determine the prevalence of HIV‐1 subtypes and transmitted drug‐resistance mutations in blood donors from the Catalonian region (northeastern Spain).
