Infections - Zoster

Herpes zoster (or simply zoster), commonly known as shingles and sometimes referred to as zona, is a viral disease characterized by a painful skin rash with blisters in a limited area on one side of the body, often in a stripe. The initial infection with varicella zoster virus (VZV) causes the acute (short-lived) illness chickenpox which generally occurs in children and young people. Once an episode of chickenpox has resolved, the virus is not eliminated from the body but can go on to cause shingles—an illness with very different symptoms—often numerous years after the initial infection.

Varicella zoster virus can become latent in the nerve cell bodies and less often in non-neuronal satellite cells of dorsal root, cranial nerve or autonomic ganglion, without causing any symptoms. Years or decades after a chickenpox infection, the virus could break out of nerve cell bodies and travel down nerve axons to cause viral infection of the skin in the region of the nerve. The virus could spread from one or more ganglia along nerves of an affected segment and infect the corresponding dermatome (an area of skin supplied by one spinal nerve) causing a painful rash. Although the rash usually heals within two to four weeks, some sufferers experience residual nerve pain for months or years, a condition called postherpetic neuralgia. Exactly how the virus remains latent in the body, and subsequently re-activates is not understood.

Throughout the world the incidence rate of herpes zoster every year ranges from 1.2 to 3.4 cases per 1,000 healthy individuals, increasing to 3.9–11.8 per year per 1,000 individuals among those older than 65 years. Antiviral drug treatment can reduce the severity and duration of herpes zoster if a seven- to ten-day course of these drugs is started within 72 hours of the appearance of the characteristic rash.
