Figure Lengend Snippet: Serological study 1: ViroTrack Sero Zika IgG/IgM serological evidence study. ( a ) ZIKV IgM measured by ViroTrack Sero Zika IgG/IgM. ( b ) ZIKV IgM measured by DIA.PRO ZIKV ELISA kit. ( c ) ZIKV IgG measured by ViroTrack Sero Zika IgG/IgM. ( d ) ZIKV IgG measured by DIA.PRO ZIKV ELISA kit. ZIKV IgM and IgG values were measured by ViroTrack Sero Zika IgG/IgM for serial draw samples collected on different days from illness for 3 different ZIKV RT-PCR positive patients from the Dominican Republic. The expected seroconversion pattern is clearly measurable, and it is comparable with the ZIKV IgG and IgM patterns measured by commercial ZIKV ELISA kits.

Article Snippet: In serological study 1, we included three serial ZIKV samples (cat.no.1043-TDS-0220, 1043-TDS-0230 and 1043-TDS-0238) from the Dominican Republic (Boca Biolistics, Pompano Beach, FL, USA).

Figure Lengend Snippet: Serological study 3: Zika and dengue differential study. ( a ) ROC curve analysis by R for differentiation of ZIKV- from DENV-infected samples based on ZIKV IgG measurements: four groups of samples were analyzed, they are 25 pZIKV-infected samples, 25 DENVpZIKV-infected samples, 25 pDENV-infected samples and 25 sDENV samples; and ( b ) ROC curve analysis by R for differentiation of ZIKV- from DENV-infected samples based on ZIKV IgM measurements: four groups of samples were analyzed, they are 25 pZIKV-infected samples, 25 DENVpZIKV-infected samples, 25 pDENV-infected samples and 25 sDENV samples. ( c ) Violin plot of ViroTrack Sero Zika IgG/IgM measurements on ZIKV IgG and ( d ) IgM level from serum samples from four groups of samples as described in ( a ). ( e ) Violin plot of ViroTrack Sero Zika IgG/IgM measurements on ZIKV IgG level to compare primary and secondary DENV-infected samples from 25 serum samples with primary DENV infection collected at convalescent phase (around 20 days post-onset of illness), 25 serum samples with secondary infection collected at convalescent phase (around 20 days post-onset of illness), 20 serum samples with primary DENV infection (pDENV_>3MPO, sample collected 3 months post-onset of illness) and 20 serum samples with secondary DENV infection (sDENV_>3MPO, sample collected 3 months post-onset of illness). ( f ) Both sDENV samples from different stages of illness onset show significantly higher IgG levels than both groups of pDENV samples. ** p ≤ 0.05, **** p ≤ 0.0001.
