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.
Chickenpox, also known as varicella (/ ˌ v ɛ r ə ˈ s ɛ l ə / VER-ə-SEL-ə), is a highly contagious, vaccine-preventable disease caused by the initial infection with 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 ...
Diagnosis is typically based on the signs and symptoms presented. [3] 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.
The varicella-zoster virus (VZV) causes chicken pox — as well as shingles. It’s unlikely to get chicken pox if you’ve had the chicken pox vaccine. Chicken pox treatments
Other symptoms to note: Chicken pox rashes typically start toward the middle of the body and work outward toward the extremities. It can often cause pockmarked scars after the blisters heal.
Shingles, also called zoster or herpes zoster, is a viral infection that affects the nerves.
Postherpetic neuralgia (PHN) is neuropathic pain that occurs due to damage to a peripheral nerve caused by the reactivation of the varicella zoster virus (herpes zoster, also known as shingles). PHN is defined as pain in a dermatomal distribution that lasts for at least 90 days after an outbreak of herpes zoster. [1]
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.
