Epidemiology of dengue in Argentina: Antibodies seroprevalence in blood donors and circulating serotypes

Currently, dengue virus (DENV) infection is a world public health concern. In recent decades, three major outbreaks and a substantial growth of DENV infection prevalence have been observed in Argentina. However, there is a paucity of data on DENV epidemiology in this country. To estimate DENV antibo...

Zusammenfassung:Currently, dengue virus (DENV) infection is a world public health concern. In recent decades, three major outbreaks and a substantial growth of DENV infection prevalence have been observed in Argentina. However, there is a paucity of data on DENV epidemiology in this country. To estimate DENV antibodies seroprevalence and determine the circulating serotypes in a population-based study. Anti-DENV IgG antibodies were determined in 1,530 prospectively collected samples from blood donors throughout the country (April 2020 to April 2021). DENV serotyping was performed in 251 retrospectively analyzed samples (2016-2020). Overall, anti-DENV IgG was detected in 220 (14.4%) blood donors. Seroprevalence was significantly higher in men (17.3%) than in women (11.3%), p
