Human herpesvirus 6 (HHV-6) is the common collective name for human herpesvirus 6A (HHV-6A) and human herpesvirus 6B (HHV-6B). These closely related viruses are two of the nine known herpesviruses that have humans as their primary host. [1]
HHV-7 is a member of Betaherpesvirinae, a subfamily of the Herpesviridae that also includes HHV-6 and Cytomegalovirus (HHV-5 or HCMV). [3] [4] HHV-7 often acts together with HHV-6, and the viruses together are sometimes referred to by their genus, Roseolovirus. [5] HHV-7 was first isolated in 1990 from CD4+ T cells taken from peripheral blood ...
Schematic drawing of a Herpesviridae virion. All members of the Herpesviridae share a common structure; a relatively large, monopartite, double-stranded, linear DNA genome encoding 100–200 genes encased within an icosahedral protein cage (with T=16 symmetry) called the capsid, which is itself wrapped in a protein layer called the tegument containing both viral proteins and viral mRNAs and a ...
HHV-6 has been further classified into HHV-6A and HHV-6B, two distinct viruses that share 88% of the same DNA makeup, with HHV-6B the most common cause of roseola. [4] [13] After infection, these viruses enter a latent phase. Roseola caused by HHV-7 has been linked to the ability of HHV-7 infection to reactivate latent HHV-6. [6]
Herpes simplex, often known simply as herpes, is a viral infection caused by the herpes simplex virus. [5] Herpes infections are categorized by the area of the body that is infected. The two major types of herpes are oral herpes and genital herpes, though other forms also exist. Oral herpes involves the face or mouth.

Roseolovirus is a genus of viruses in the order Herpesvirales, in the family Herpesviridae, in the subfamily Betaherpesvirinae. There are currently six species in this genus. Diseases associated with this genus include: HHV-6: sixth disease (roseola infantum, exanthema subitum); HHV-7: symptoms analog to the 'sixth disease'. [1] [2]
Herpes simplex virus (HSV)-1 affects more than half of all people in the U.S. by the time they reach their 20s. They typically cause tiny, clear and fluid-filled blisters known as cold sores or ...
