^aInfants were laboratory-confirmed with ZIKV infection by rRT-PCR within 1 wk of symptom onset at 1–12 mo of age.

^bPreterm birth refers to an infant born at less than 37 wk of age.

^cPercentiles were based on sex- and age-adjusted using World Health Organization standards.

^dOne of the children with hypotonia had a diagnosis of Down syndrome, and the other child had sensorineural hearing loss.

^eTwo of these three children did not receive diagnostic ABR.

^fOne child with a structural abnormality had retinal scarring and reported congenital toxoplasmosis, and one child had an optic nerve pit.

^gTwo children with possible visual impairment had diagnoses of strabismus, independent from those children with structural abnormalities.

^hPercentages may not sum to 100 due to rounding.
