Chickenpox, also known as varicella (/ ˌ v ɛ r ə ˈ s ɛ l ə / VER-ə-SEL-ə), is a highly contagious disease caused by varicella zoster virus (VZV), a member of the herpesvirus family. [3] [7] [5] The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over. [1] It usually starts on the ...
Varicella zoster virus (VZV), also known as human herpesvirus 3 (HHV-3, HHV3), 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.
Varicella zoster virus is not the same as herpes simplex virus, although they both belong to the alpha subfamily of herpesviruses. [14] Shingles vaccines reduce the risk of shingles by 50 to 90%, depending on the vaccine used. [1] [15] Vaccination also decreases rates of postherpetic neuralgia, and, if shingles occurs, its severity. [1]

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 ...
A zoster vaccine is a vaccine that reduces the incidence of herpes zoster (shingles), a disease caused by reactivation of the varicella zoster virus, which is also responsible for chickenpox. [8] Shingles provokes a painful rash with blisters, and can be followed by chronic pain (postherpetic neuralgia), as well as other complications.
The rash looks similar to other illnesses, like genital herpes and syphilis. A monkeypox rash can take the form of pimples or blisters. The rash looks similar to other illnesses, like genital ...
