In this review we summarize current knowledge related to the identification of pregnancies that may be complicated by genital herpes and describe the consequences of maternal infections with genital herpes. We address the implications of this information for the management of genital herpes during pregnancy and at delivery and for the care of neonates exposed to herpes simplex virus at delivery. On the basis of the current data, we cannot make specific recommendations concerning many of the clinical problems that are caused by herpes simplex virus infections in pregnant women. We identify and discuss unresolved questions about optimal management. © 1992 Oxford University Press.
