Brazil |
77 children (ages 11, 18 and 24 months) |
All children evaluated in the study showed clinical diagnosis of cerebral palsy (PC) at 2 years of age. Seventy-four (96.1%) showed motor skills similar to children aged 4 months or less, and 73 (94.8%) children had quadriplegia. No significant difference (p = 0.076) was found between 18 and 24 months. |

Colombia |
12 newborns |
The main abnormalities found in the MRI examination were (11/12; 91.7%) calcifications and ventriculomegaly, abnormalities of the corpus callosum (12/12; 100%), cortical malformations (8/9; 89%). At birth, most of the affected neonates (55.6%-77.8%) presented measurements of PC > 3 and standard deviation below medium. |

Characterize the ophthalmic manifestations of confirmed or suspected prenatal exposure to zika virus (ZIKV) |
Brazil |
224 breastfeeding infants |
Abnormalities in the CNS (40.2%), including microcephaly (27.7%). Eye abnormalities were found in 49 of 90 infants (54.4%) and correlated with the presence of CNS findings (odds ratio 14.9; 95% CI: 7.3-30.3; p < 0.0001). Of the children without microcephaly or other abnormalities in the CNS, 3.7% had ocular abnormalities. |

Brazil |
173 children with microcephaly |
Of the children evaluated, 49.1% presented abnormal findings in the CNS; 35.8%, microcephaly; and 13.3%, other abnormalities in the CNS without microcephaly. Abnormal visual function was present in 30% of children; eye alterations in 26%; nystagmus in 15,6%. |

French Guiana, Guadeloupe and Martinique |
546 pregnant women with ZIKV |
Neurological and ocular abnormalities associated with ZIKV infection were observed in 39 newborns (7.0%; CI: 95%, 5.0 to 9.5). Microcephaly was detected in 32 fetuses and newborns (5.8%): in 1.6%, it was severe; in 1.6%, it was moderately disproportionate; and in 2.5%, it was moderately proportional. Severe microcephaly or other brain abnormalities were observed in 17 fetuses and newborns (3,1%). |

Investigate the sleep characteristics of newborns/breastfeeding infants (88 with CZS and 48 with healthy development, age, and paired sex) using the Child Sleep Questionnaire. |
Brazil |
136 newborns and infants |
Of children with CZS, 34.1% had poor sleep; 3.5% had more than three night awakenings; 15% were awake at night for more than an hour; and 24% had less than nine hours of total sleep time. The average time to start sleeping at night was later for the CZS group. When the duration of night sleep was analyzed, 51% of the CZS group and 20.8% of the healthy group had less than nine hours of sleep. |

The average growth rate was lower in the group of children with CZS (p < 0.05) in weight and cephalic perimeter measurements at 20.5 months of age. There was a significant difference (p = 0.000) in cognitive and motor performance between the groups. |

Of the children, 81% had severe hypertonia and multiple contractures; 83.8% had visual impairment, of which 41.9% had severe impairment; 17% had hearing impairment; 11% had arthrogryposis. No child showed age-appropriate motor skills. Only one (1.9%) was able to sit without support or walk without support. About 50% did not hold a small object in their hands and was unable to drink liquid in a glass. |

Of the children, 40% presented alterations observed in echocardiography, while 10.8% had heart defects such as interatrial communication, ventricular interatrial communication, and persistence of the ductus arteriosus. The frequency of heart defects was observed in newborns that were exposed in the 2nd trimester of pregnancy or in those in which the image examination of the (CNS) was altered in the postnatal period or in premature. |
