Human herpesviruses 6 and 7.
Human herpesviruses 6 and 7 are newly discovered viruses that belong to the genus Roseolavirus within the subfamily Betaherpesvirinae. These ubiquitous viruses may cause primary or chronic persistent infection or remain in a state of latency for many years, until a decrease in the immunologic state of the host leads to reactivation of infection. Several diseases have been linked with HHV-6 and HHV-7. In the dermatologic arena, a definite association has been proven only for HHV-6 and exanthema subitum (roseola infantum), whereas the role of HHV-7 in the pathogenesis of pityriasis rosea remains a matter of debate.
