Intrauterine herpes simplex virus infection

Abstract

Neonatal herpes simplex virus (HSV) infection usually is the consequence of intrapartum infection, with disease onset between 5 and 15 days of life. More recently, intrauterine HSV infection has been identified. Intrauterine infection is apparent within the first 24-48 hr of life and is associated with skin vesicles/scarring, chorioretinitis, and/or hydraencephaly. The recognition that babies with these findings can have disease caused by HSV should prompt enhanced physician awareness in the evaluation of newborns with suspected intrauterine infection. The frequency of intrauterine infection appears to be about 5% of all babies with neonatal HSV infection.
