Abstract
Most cases of acute infections caused by human herpesvirus 7 (HHV-7) are asymptomatic or very mild. Clinical symptoms disappear spontaneously; however, the infection becomes latent and persists for life with periodic asymptomatic reactivation. Little is known about the virus’s ability to cross the blood–brain barrier. Our case of an immunocompetent infant indicates that HHV-7 infection should be considered a cause of neuroinfection, not only in immunocompromised patients but also in the youngest immunocompetent patients.
