Human Herpesvirus 6 - HHV6

Human herpesvirus 6 (HHV6), a member of the β-herpesvirus subfamily, exists as two closely related variants, HHV6A and HHV6B. A large portion (>90%) of the population is infected with HHV early in life, at which time the virus can cause a mild, self-limited syndrome called roseola. In immunocompromised patients, HHV6 reactivation can cause life-threatening diseases such as myocarditis, liver failure, and encephalitis. Reactivated HHV6 can also facilitate activation of other viruses and allow the spread of fungal infection.
