A Review on Microcephaly Associated with Zika Fever in New Born Babies

A widespread epidemic of Zika virus (ZIKV) infection was reported in 2015 in South and Central America and
the Caribbean. A major concern associated with this infection is the apparent increased incidence of
microcephaly in fetuses born to mothers infected with(ZIKV). In this report, it was described the case of an
expectant mother who had a febrile illness with rash at the end of the first trimester of pregnancy living in Brazil.
Ultrasonography performed at 29 weeks of gestation revealed microcephaly with calcifications in the fetal brain
and placenta. After the mother requested termination of the pregnancy, a fetal autopsy was performed. Microcephaly (an abnormally small brain) was observed, with almost complete agyria, hydrocephalus, and multifocal dystrophic calcifications in the cortex and subcortical white matter, with associated cortical displacement and mild focal inflammation. ZIKV was found in the fetal brain tissue on reverse-transcriptase– polymerase-chain-reaction (RT-PCR) assay, with consistent findings on electron microscopy. The complete genome of (ZIKV) was recovered from the fetal brain.
