Human Herpes Virus 7 - HHV-7. In 1990, four years after the isolation of HHV-6, another herpesvirus was discovered. Because of the similarities in genes HHV-6 and HHV-7 and the fact that HHV-7 often acts together with HHV-6, and the viruses together are sometimes referred to as Roseolovirus.
Herpesviridae is a large family of DNA viruses that cause diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word herpein ("to creep"), referring to the latent, recurring infections typical of this group of viruses.
Herpes simplex virus 1 and 2 (HSV-1 and HSV-2), also known as human herpesvirus 1 and 2 (HHV-1 and HHV-2), are two members of the herpesvirus family, Herpesviridae, that infect humans.
