Blood donor serosurveys and national dengue burden estimates in Argentina

Year: 2026

Type: article

Abstract: Blood donor serosurveys can be valuable for haemovigilance. Flichman and colleagues report increasing anti-dengue virus (DENV) IgG seroprevalence in blood donors from three Argentine regions and detectable DENV RNA in donors during the 2022–23 outbreak.1 These findings support targeted assessment of transfusion risk. However, the use of these data to infer that approximately 10.2 million new infections occurred nationally raises important concerns about target population, sampling frame, and precision.
