A prospective study of neurodevelopmental trends between 3 and 24 months in normocephalic infants with prenatal Zika virus exposure: Evidence of emerging communication delays in the NATZIG cohort.

Developmental trends between 3 and 24 months were assessed in 194 normocephalic infants with prenatal Zika virus exposure. Bayley Scales of Infant and Toddler Development Screening Test-3rd Edition cognitive scores remained in the typical range. Communication skills developed at a slower rate suggesting that neurodevelopmental delays may emerge at older ages.
