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.
From this name it can be ascertained that the virus' primary natural host is a canid (i.e. a member of the family Canidae; dogs etc.), that it is a member of the family Herpesviridae and subfamily Alphaherpesvirinae, and that it is the first herpesvirus named for which canids serve as primary natural hosts. A number of virus names (e.g. Epstein ...
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.
Herpesviruses have some of the largest genomes among human viruses, often encoding hundreds of proteins. For instance, the double‑stranded DNA (dsDNA) genome of wild-type HCMV strains has a size of around 235 kb and encodes at least 208 proteins. It is thus longer than all other human herpesviruses and one of the longest genomes of all human ...
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 ...
Following active infection, herpes viruses establish a latent infection in sensory and autonomic ganglia of the nervous system. The double-stranded DNA of the virus is incorporated into the cell physiology by infection of the nucleus of a nerve's cell body .
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]
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]
