Neonatal herpes simplex fulminant hepatitis successfully treated with acyclovir.

Disseminated neonatal herpes simplex virus (HSV) infection is characterized by progressive multiple organ failure and high mortality rates up to 85% for untreated neonates. It can result from infection with either HSV-1 or HSV-2. We report the first known case of disseminated neonatal herpes associated with fulminant liver failure caused by HSV-2 who survived without liver transplant.
