Herpesviridae, the herpes family of viruses that infects humans, consists of 8 separate species: herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), varicella zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus, human herpesvirus 6 (HHV-6), human herpesvirus 7 (HHV-7), and human herpesvirus 8 (HHV-8).
18) Human herpesvirus 7 has been linked to pityriasis rosea.
Much remains to be learned about the pathogenic role of [beta]-herpesviruses (cytomegalovirus [CMV], human herpesvirus 6 variants A and B [HHV-6A and HHV-6B], and human herpesvirus 7 [HHV-7]) in immune-compromised children.
Biologic properties of human herpesvirus 7 strain SB.
Human herpesvirus 7
is a T-lymphotropic virus and is related to, but significantly different from, human herpesvirus 6 and human cytomegalovirus.
Human herpesvirus 7 exhibits tropism that is similar to that of HHV-6, and HHV-7 also infects humans in early childhood and persists subsequently as a latent infection.
Reactivation of human herpesvirus 6 by infection of human herpesvirus 7.
Invasion by human herpesvirus 6 and human herpesvirus 7 of the central nervous system in patients with neurological signs and symptoms.
Human herpesvirus 7 is a constitutive inhabitant of adult human saliva.
Detection of human herpesvirus 6 and human herpesvirus 7 in the submandibular gland, parotid gland, and lip salivary gland by PCR.
More than 100 additional HHV-6 strains have been isolated from PBMCs of children with subitum or febrile syndromes (8), from cell-free saliva of healthy or HIV-infected patients (9,10), from PBMCs of patients with chronic fatigue syndrome (CFS) (11), and from PBMCs of healthy adults--these PBMCs were cultivated for human herpesvirus 7 (HHV-7) isolation (12).
