Herpes zoster, also known as shingles, is caused by varicella zoster virus (VZV). Herpes zoster may occur at any age, but more frequently seen in elderly population with peak incidence is between ages 50 and 70. The higher incidence among elderly persons may be related to a decrease in cellular immunity. However, people who are using immunosupressants or immune-compromised (malignancy, surgery, trauma) are also at higher risks of developing shingles. Although the rash will heal by itself in a few weeks, many patients may suffer from residual nerve pain called postherpetic neuralgia that can last from months to years.
