Shingles Overview

Shingles is a reactivation of the herpes zoster virus (varicella-zoster virus, or VZV). This same virus causes the childhood illness chickenpox. The chickenpox virus (varicella) remains in a dormant state in the body in the root of nerves that control sensation. In about 1 out of 5 people, the virus "wakes up," often many years after the chickenpox infection. The virus then travels along a sensory nerve into the skin causing a painful rash known as shingles.

• Shingles is derived from the Latin and French words for belt or girdle, reflecting distribution of the rash in a broad band. This band is usually only on one side of the body and represents a dermatome—the area that a single sensory nerve supplies in the skin.

• Anyone who has had the chickenpox infection or vaccine can get the herpes zoster virus that causes shingles. Older people and those with cancer, HIV, or organ transplants have a decreased ability to fight off infection and a greater chance of getting shingles.

• The majority of people with shingles, however, are healthy. No special tests need to be done to see if your immune system is strong.
