Herpes zoster, or shingles, caused by a reactivation of the chickenpox virus, can occur in patients of any age, but is more common in older adults.

This article describes recent changes in diagnostic testing, treatment, prevention, and practice guidelines as well as the approach clinicians should take when evaluating patients with herpes zoster and assessing risk for complications.
