Prolonged maternal postpartum fever and neonatal herpes infection.

Maternal postpartum fever that is suggestive of endometritis often triggers evaluation of the mother and newborn infant for bacterial infection. Two neonates whose mothers had persistent postpartum fever despite broad-spectrum antimicrobial therapy developed disseminated herpes simplex virus (HSV) infection. Obstetric and pediatric healthcare providers should be mindful of possible HSV infection if there is postpartum fever unresponsive to antibiotics, and both mother and neonate should be evaluated appropriately and treated promptly.
