High performance assays are essential for the serological diagnosis of recent and past Zika virus (ZIKV) infections but few are presently available. We used two commercially available NS1 antigen-based enzyme-linked immunoassays to study the kinetics of anti-ZIKV IgM and IgG in fifteen ZIKV-infected patients for up to 180days after clinical onset. The Diapro assay detected anti-ZIKV IgM reactivity more frequently (100%) and for longer (median 53days) than did the Euroimmun assay (60%; 13days, p<0.005). Both assays detected anti-ZIKV IgG reactivity 11days after clinical onset in all subjects. ZIKV IgG reactivity decreased in 3 subjects, suggesting long term false negative results with the Euroimmun assay. Existing anti-Dengue antibodies seem to modify the detection of ZIKV IgG but the specificity of the immunoassays was not assessed. These enzyme-linked immunoassays were user-friendly and provided results rapidly in our hands but they need further assessment before being widely used for diagnosis or public health surveys.
