Neonatal herpes simplex

Neonatal herpes simplex, or simply neonatal herpes, is a herpes infection in a newborn baby, caused by the herpes simplex virus (HSV). It occurs mostly as a result of vertical transmission of the HSV from an affected mother to her baby. Types include skin, eye, and mouth herpes (SEM), disseminated herpes (DIS), and central nervous system herpes (CNS). Depending on the type, symptoms vary from a fever to small blisters, irritability, low body temperature, lethargy, breathing difficulty, and a large abdomen due to ascites or large liver. There may be red streaming eyes or no symptoms.
