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.
Human herpesvirus 6A (HHV-6A) is a species of virus in the genus Roseolovirus, subfamily Betaherpesvirinae, family Herpesviridae, and order Herpesvirales. [ 1 ] [ 2 ] HHV-6A and infertility
Human herpesvirus 6B affects humans. Primary infection with this virus is the cause of the common childhood illness exanthema subitum (also known as roseola infantum or sixth disease). Additionally, reactivation is common in transplant recipients, which can cause several clinical manifestations such as encephalitis , bone marrow suppression ...
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 ...
Human herpesvirus 7 (HHV-7) Human cytomegalovirus (HCMV, HHV-5) "seems to have a large impact on immune parameters in later life and may contribute to increased morbidity and eventual mortality." [5] Human herpesvirus 6A (HHV-6A) has been described as more neurovirulent, [6] and as such is more frequently found in patients with ...
It is caused by human herpesvirus 6 (HHV-6A, HHV-6B) or human herpesvirus 7 (HHV-7). [1] Spread is usually through the saliva of those who are otherwise healthy. [1] [2] However, it may also spread from the mother to the baby during pregnancy. [1] Diagnosis is typically based on symptoms and does not need to be confirmed with blood tests (PCR ...
Human gammaherpesvirus 4, or Epstein–Barr virus, one of the most common viruses which can cause various diseases; Human betaherpesvirus 5; Roseolovirus, a genus that includes three human herpesviruses: Human herpesvirus 6, the collective name for Human betaherpesvirus 6A and Human betaherpesvirus 6B; Human betaherpesvirus 7
Herpesviruses represent a group of double-stranded DNA viruses distributed widely within the animal kingdom. The family Herpesviridae, which contains eight viruses that infect humans, is the most extensively studied group within this order and comprises three subfamilies, namely Alphaherpesvirinae, Betaherpesvirinae and Gammaherpesvirinae.
