Data on molecular, serological, and immunological diagnosis for Zika virus (ZIKV) and Dengue virus (DENV) infection in a pregnant woman from El Salvador are shown. ZIKV infection in the DENV-infected mother was documented and transmission was not reported. cMRI/cUS: cerebral magnetic resonance imaging/cerebral ultrasonography; PRNT: plaque reduction neutralization test; WOP: week of pregnancy; EIA: enzyme immunoassay; IFA: immunofluorescence assay; Nt-Ab; neutralizing antibodies. In the box of molecular diagnosis, black numbers specify the week of pregnancy, while red numbers in brackets indicate the exact day of gestation. The blockade-of-binding (BOB) assay result is expressed as the ratio of inhibition, while the ELISpot assay is measured as net spots/million PBMC.
