Herpes simplex virus 2 is periodically shed in the human genital tract, most often asymptomatically. Most sexual transmissions occur during periods of asymptomatic shedding. [ 6 ] Asymptomatic reactivation means that the virus causes atypical, subtle, or hard-to-notice symptoms that are not identified as an active herpes infection, so acquiring ...
Kaposi's sarcoma-associated herpesvirus (KSHV) is the ninth known human herpesvirus.It is also called Human herpesvirus 8, or HHV-8 in short. [2] This virus causes Kaposi's sarcoma, a cancer commonly occurring in AIDS patients, [3] as well as primary effusion lymphoma, [4] HHV-8-associated multicentric Castleman's disease and KSHV inflammatory cytokine syndrome.

Herpes simplex virus 1 and 2 (HSV-1 and HSV-2) are two members of the human Herpesviridae family, a set of viruses that produce viral infections in the majority of humans. [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.
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 ...
The herpes simplex virus type 1 (HSV-1) mutant 1716 lacks both copies of the ICP34.5 gene, and as a result is no longer able to replicate in terminally differentiated and non-dividing cells but will infect and cause lysis very efficiently in cancer cells, and this has proved to be an effective tumour-targeting strategy.
The researchers tested three different strains of herpesviruses: Epstein-Barr virus, the cause of mononucleosis and some cancers; Herpes simplex viruses (HSV-1) and (HSV-2), which cause cold sores and genital herpes respectively; and human cytomegalovirus, which causes congenital herpes. The results indicated that CRISPR can be used to ...
Both HSV-1, and HSV-2 can be the cause of herpetic gingivostomatitis, [5] although HSV-1 is the source of infection in around 90% of cases. [6] Herpetic gingivostomatitis infections can present as acute or recurrent. Acute infection refers to the first invasion of the virus, and recurrent is when reactivation of the latent virus occurs. [7]
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 (VZV or HHV-3; the cause ...
