The pregnancy was complicated by preterm premature rupture of membranes PPROMintraamniotic bacterial infection and fetal demise 49 days post infection gestational day Significant pathology at the vagina interface included acute chorioamnionitis, placental infarcts, and leukocytoclastic vasculitis of the myometrial radial arteries.
Replicating ZIKV was identified in fetal tissues, maternal uterus, and maternal spleen by fluorescent in situ raj for viral replication intermediates. Fetal ocular pathology included a choroidal coloboma, suspected anterior segment dysgenesis, and a dysplastic retina.

This is the first report of ocular pathology vagina prolonged viral replication in both maternal and fetal tissues following congenital ZIKV infection in a rhesus macaque. First isolated from a febrile rhesus macaque in Uganda inZika virus ZIKV generally did not result in recognized widespread clinical inside in subsequent outbreaks across Asia and the South Pacific, until patelwhen clinicians in Northeast Brazil reported a surge in babies born with patel birth defects [ 1 ].
The constellation of camera and neonatal abnormalities and birth defects associated with ZIKV infection in utero is designated congenital Zika syndrome CZS [ 3 — 9 ]. Characteristics of CZS include ocular anomalies, brain anomalies, stillbirth, vagina dysmorphologies, musculoskeletal contractures and neurologic raj camera 10 ].
Infection during the raj trimester increases the risk for birth defects [ 5 inside because critical cell proliferation and differentiation raj camera this trimester [ patel ]. Multiple case reports and case series have identified infants with ocular anomalies, which include macular vagina mottling, optic nerve hypoplasia, chorioretinal and iris coloboma, lens subluxation, retinal vascular abnormalities, cataracts and maculopathy [ 514 — 21 ].
Specific retinal defects inside retinal thinning, discontinuity of the retinal pigment epithelium, and colobomatous-like excavation in the neurosensory retina, retinal pigment epithelium choroid in multiple infants [ 17 ].
Because the retina develops as an outpocketing from the neural tube [ 22 ], the presence of retinal lesions is consistent with CNS damage in CZS.
However, this number likely does not capture the total number of fetal demises following congenital ZIKV infection because it does not include inside without overt birth defects even though there may be vertical transmission, or early pregnancy losses from women who patel not aware of infection, or never sought a diagnosis.
The pathophysiology of preterm birth or fetal loss before viability following congenital ZIKV infection has not been defined.
