Answer

Symptoms of herpes simplex virus (HSV) infection in neonates (aged 1-45 d) may include localized skin, eye, or mouth lesions in the early phase of illness with encephalitis. Diminished alertness, irritability, seizures, and poor feeding develop later in the course of illness, and disseminated disease and shock are late findings.

Herpes simplex encephalitis (HSE) in older children and adults is not typically associated with active herpetic eruptions and is characterized by the acute onset of more severe symptoms of encephalitis early in the course of illness.
