Nine herpesvirus types are known to primarily infect humans, [7] at least five of which are extremely widespread among most human populations, and which cause common diseases: herpes simplex 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial and genital herpes), varicella zoster (or HHV-3; the cause of ...
Herpes virus DNA contains a gene for a protein called ICP4, which is an important transactivator of genes associated with lytic infection in HSV-1. [47] Elements surrounding the gene for ICP4 bind a protein known as the human neuronal protein neuronal restrictive silencing factor (NRSF) or human repressor element silencing transcription factor ...
The subfamily name is used for viruses from members of the family Bovidae or from primates (the virus name ending in –ine, e.g. bovine), and the host family name for other viruses (ending in –id, e.g. equid). Human herpesviruses have been treated as an exception (human rather than hominid).
The Human alphaherpesvirus 1 virus can be classified into six clades. [2] Four of these occur in East Africa, one in East Asia and one in Europe and North America. This suggests that the virus may have originated in East Africa. The most recent common ancestor of the Eurasian strains appears to have evolved ~60,000 years ago. [3]
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.
Herpes virus may refer to: Any member of the large family of DNA viruses known as Herpesviridae. Human herpesviruses, nine types of herpesviruses that can cause diseases in humans Herpes simplex virus 1 and 2, responsible for herpes simplex infections; Human alphaherpesvirus 3, also called varicella-zoster virus, responsible for chickenpox and ...
Human herpesvirus 6 (HHV-6) is the common collective name for human betaherpesvirus 6A (HHV-6A) and human betaherpesvirus 6B (HHV-6B). These closely related viruses are two of the nine known herpesviruses that have humans as their primary host. [1]
Varicella zoster virus (VZV), also known as human herpesvirus 3 (HHV-3, HHV3) or Human alphaherpesvirus 3 (taxonomically), is one of nine known herpes viruses that can infect humans. It causes chickenpox (varicella) commonly affecting children and young adults, and shingles (herpes zoster) in adults but rarely in children.
