Congenital varicella syndrome occurs in 2% of children born to women who develop varicella during the first or second trimester of pregnancy. [24] It manifests as intrauterine growth retardation, microcephaly, cortical atrophy, limb hypoplasia, microphthalmia, cataracts, chorioretinitis, and cutaneous scarring. Fetal injury risk is unrelated to the severity of disease in the mother. Zoster exposure during pregnancy has not been associated with fetal injury.
