First case of confirmed congenital Zika syndrome in continental Africa

Trans R Soc Trop Med Hyg. 2018 Oct 1;112(10):458-462. doi: 10.1093/trstmh/try074.

Abstract

Background: Zika virus has been responsible for recent outbreaks in the western hemisphere with known neurological complications such as microcephaly. This complication has not been previously documented in continental Africa.

Methods: Neurological evaluation of the newborn was performed after birth, at one and two months of age. The mother and the newborn sera samples were tested by immunofluorescent assay (IFA; immunoglobulin G [IgG] and IgM) for Zika virus and the presence of Zika virus ribonucleic acid (RNA) was checked by qualitative real-time reverse transcription polymerase chain reaction (RT-PCR) in placenta, blood and urine samples.

Results: We report on a newborn, born in Portugal, with microcephaly with confirmed congenital Zika virus infection (Asian lineage) imported from Angola with typical clinical and imaging findings.

Conclusions: To our knowledge this is the first report that shows the circulation of the Asian lineage in Angola and the first report of a congenital Zika syndrome in continental Africa.
