Herpes Zoster in the Older Adult

Herpes zoster (HZ) is the result of reactivation of latent varicella zoster virus and occurs most frequently in older adults. Classically, HZ presents as a unilateral, self-limited, dermatomal rash. Postherpetic neuralgia (PHN) is a common sequela, presenting as severe pain that persists after the rash has resolved. In the elderly, PHN can be debilitating and requires a prompt diagnosis, treatment with antivirals, and adequate pain control. A longer term pain management strategy is required if PHN occurs. A modestly effective vaccine exists and is recommended for older individuals.
