Neonatal herpes simplex 2 infection presenting with supraglottitis.

Abstract

Herpes simplex virus (HSV) is a double stranded DNA virus capable of causing primary and recurrent infection. We describe an unusual case of neonatal HSV-2 infection presenting with supraglottitis. Despite a 2 month course of intravenous aciclovir followed by 2 months of oral valaciclovir, the infant subsequently developed HSV-2 encephalitis which responded to further antiviral treatment. The subsequent diagnosis of encephalitis highlights the importance of testing CSF for HSV to establish the presence of CNS infection in neonates and thus the potential benefit of longer term suppressive antiviral therapy.
