Human Herpesvirus 6 encephalitis in an immunocompetent pregnant patient and review of the literature

Central nervous system infection caused by Human Herpesvirus 6 (HHV-6) is well known in immunocompromised; however, data regarding immunocompetent patients is limited to case series. We describe a 29-year-old immunocompetent pregnant woman with meningoencephalitis due to HHV-6 and review current literature. HHV-6 should be kept in mind in patients with meningoencephalitis of unknown etiology.
