Herpes zoster occurs in 10% to 20% of the general population as a result of reactivation of the varicella-zoster virus (VZV) and is generally benign. It occurs more frequently in persons with cellular immunodeficiency and older age. The association between herpes zoster and HIV was confirmed early in the course of the HIV epidemic by numerous studies. Zoster was noted to precede AIDS in high-risk groups. Both the incidence and complication rate of herpes zoster are increased in HIVinfected patients.
