Developmental impacts of perinatal infections

Abstract

Purpose of review: Perinatal infections and their potential consequences on child neurodevelopment have become a topic of greater interest over the past decade. The purpose of this review is to describe the current knowledge of neurodevelopmental impacts from some of these infections including congenital cytomegalovirus, Zika virus, Chikungunya, and severe acute respiratory syndrome coronavirus 2. These infections have had recent publications about neurodevelopmental impacts.

Recent findings: Children with congenital cytomegalovirus infection, especially those with symptomatic infection, are at a high risk for developmental delays. They also seem to be at an increased risk for autism spectrum disorder. Studies indicate that prenatal exposure to severe acute respiratory syndrome coronavirus 2 may also be a risk factor for developmental delay and that all children exposed prenatally should be followed more closely for early neurodevelopment. Children with congenital Zika syndrome and birth defects are at risk for a range of neurodevelopmental sequalae and at high risk for early mortality. However, normocephalic children with antenatal Zika virus exposure are also at risk for a range of neurodevelopmental effects including lower cognitive performance at school age.

Summary: Congenital and perinatal infectious exposures increase the risk for impaired child neurodevelopment. All children with perinatal infections should have close neurodevelopmental follow-up during childhood.
