In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established Herpesvirus as a genus with 23 viruses among four groups. [5] As of 2020, 115 species are recognized, all but one of which are in one of the three subfamilies. [6] Herpesviruses can cause both latent and lytic infections.
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).
Herpes simplex virus 1 (cold sores) and 2 (genital herpes) (HSV-1 and HSV-2), also known by their taxonomic names Human alphaherpesvirus 1 and Human alphaherpesvirus 2, are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans.
No method eradicates herpes virus from the body, but antiviral medications can reduce the frequency, duration, and severity of outbreaks. Analgesics such as ibuprofen and paracetamol (acetaminophen) can reduce pain and fever. Topical anesthetic treatments such as prilocaine, lidocaine, benzocaine, or tetracaine can also relieve itching and pain.
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 ...
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.
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.
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]
