Description
Summary:This study aims to describe neurological, visual, and auditory findings in children whose mothers had confirmed Zika virus (ZIKV) infection during pregnancy, with most of these children not presenting congenital microcephaly; Methods: an observational, longitudinal, and prospective study was conducted in Rio de Janeiro, Brazil, from March 2015 to January 2017, involving children with in utero exposure to Zika virus, following from birth up to 30 months of age. Results: Of the 2882 pregnant women admitted, 116 had a suspected ZIKV infection, of whom 33 had laboratory confirmation. Only one child presented with congenital microcephaly. Despite this, neurodevelopment delay was observed in 36.4% of children evaluated, radiological abnormalities in 29.1%, auditory abnormalities in 8.3%, and ophthalmological abnormalities in 10%. Conclusions: Newborns of mothers with confirmed ZIKV infection during pregnancy may present with varying degrees of visual, auditory, and neurological impairment, despite the presence of congenital microcephaly.
