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.
English: Progression of shingles. A cluster of small bumps (1) turns into blisters (2) that resemble chickenpox lesions. The blisters fill with pus, break open (3), crust over (4), and finally disappear. This process takes four to five weeks. A painful condition called post-herpetic neuralgia can sometimes occur.
Shingles, also known as herpes zoster or zona, [6] is a viral disease characterized by a painful skin rash with blisters in a localized area. [2] [7] Typically the rash occurs in a single, wide mark either on the left or right side of the body or face. [1]
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 ]
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 ...
The heterophile antibody test is a screening test that gives results. Serological tests take longer time, but are more accurate. Infectious mononucleosis is generally self-limiting , so only symptomatic or supportive treatments are used.
Herpes zoster ophthalmicus (HZO), also known as ophthalmic zoster, is shingles involving the eye or the surrounding area. Common signs include a rash of the forehead with swelling of the eyelid . There may also be eye pain and redness, inflammation of the conjunctiva , cornea or uvea , and sensitivity to light .
It causes chickenpox (varicella) commonly affecting children and young adults, and shingles (herpes zoster) in adults but rarely in children. As a late complication of VZV infection, Ramsay Hunt syndrome type 2 may develop in rare cases. VZV infections are species-specific to humans. The virus can survive in external environments for a few hours.
