Herpes zoster: Epidemiology, clinical features, treatment and prevention

Abstract

Herpes zoster (also called shingles) is becoming more common as the population ages. It should be part of the differential diagnosis of a localised unilateral vesicular rash, or a pruritic or painful area before the rash appears. Early management with antivirals and analgesia is important and may reduce the incidence of postherpetic neuralgia. Preventing herpes zoster with vaccination is the best way to avoid postherpetic neuralgia and other complications.
