Vibrio vulnificus necrotizing fasciitis preceding herpes zoster.

A 74-year-old white man presented with unilateral radicular pain extending across the left side of his chest and back. A diagnosis of postherpetic neuralgia, a sequela of herpes zoster, was made. Herpes zoster represents a reactivation of the varicella zoster virus that lies dormant in patients with past chickenpox. Risk factors for the disease include advanced age, stress, immunodeficiency, and immunosuppression. Treatment of herpes zoster entails traditional antiviral medications, while prevention may be achieved with a new prophylactic vaccine.
