CD40LG and infection: Prior studies that evaluated the Panbio Dengue Early Rapid test (used in this study) found that using antigen (NS1) and antibody (IgM and IgG) tests together increased the sensitivity of DENV diagnostics (93% sensitivity) and expanded the window of detection of infection.52 We found that the prevalence of DENV infections in clusters varied by DENV serotype (DENV1: 20.0%, DENV2: 36.6%).
