RDT performance in comparison to RT-qPCR stratified by age categories, VOC, and COVID-19 symptomatology. Fig. 2 A–C: RDT sensitivity (n = 351), logarithmised viral load (n = 348), and symptomatology (n = 351) in SARS-CoV-2 RNA copies/ml stratified by age categories (first year of life, 1 to 5 years, 6 to 11 years, 12 to 17 years). D portrays the logarithmised viral load in SARS-CoV-2 RNA copies/ml, separated by RDT and COVID-19 symptomatology, n = 339. The viral load of specimen of typically COVID-19 symptomatic children and adolescents exceeded statistically significant the viral load of atypically symptomatic or asymptomatic individuals. E included 346 specimens with either molecularly confirmed or epidemiologically assigned VOC (in case of no molecular VOC diagnostics or, if available, known VOC of the infection source, VOC was assigned based on the VOC corresponding to at least 90% of the German COVID-19 cases at RDT performance).F: Viral load in 306 specimens with known COVID-19 vaccination status stratified by vaccination status only and by vaccination status and RDT result. The viral load threshold of 106 SARS-CoV-2 RNA copies/ml, suggested as infectivity threshold, is added as horizontal dotted line to B,D,F. n: Number of enrolled RDT per group.
