Herpes simplex virus 2 (HHV-2 or HSV-2) is a species of virus in the genus Simplexvirus, subfamily Alphaherpesvirinae, family Herpesviridae, and order Herpesvirales. [ 1 ] [ 2 ] Evolution
[1] [2] Both HSV-1 and HSV-2 are very common and contagious. They can be spread when an infected person begins shedding the virus. As of 2016, about 67% of the world population under the age of 50 had HSV-1. [3] In the United States, about 47.8% and 11.9% are estimated to have HSV-1 and HSV-2, respectively, though actual prevalence may be much ...
Cross-species transmission is the most significant cause of disease emergence in humans and other species. [citation needed] Wildlife zoonotic diseases of microbial origin are also the most common group of human emerging diseases, and CST between wildlife and livestock has appreciable economic impacts in agriculture by reducing livestock productivity and imposing export restrictions.

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 ...
There are two types of herpes simplex virus, type 1 (HSV-1) and type 2 (HSV-2). [1] HSV-1 more commonly causes infections around the mouth while HSV-2 more commonly causes genital infections. [2] They are transmitted by direct contact with body fluids or lesions of an infected individual. [1] Transmission may still occur when symptoms are not ...
HSV epigenetics is the epigenetic modification of herpes simplex virus (HSV) genetic code.. As of 2012, an estimated 3.7 billion people globally were infected with oral herpes simplex virus (HSV-1), and 417 million were living with genital herpes (HSV-2) worldwide (World Health Organization, 2018).
Herpes genitalis caused by HSV-2 recurs on average four to six times per year, while that of HSV-1 infection occurs only about once per year. [ 12 ] People with recurrent genital herpes may be treated with suppressive therapy , which consists of daily antiviral treatment using acyclovir, valacyclovir or famciclovir. [ 13 ]
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
