Abstract
Herpes zoster develops by endogenous reactivation of varizella zoster virus (VZV). Incidence increases with age. Females are more frequently affected than males. The reactivation rate in seropositive individuals is about 20 %. After ashort prodromal stage, herpetiform-grouped vesicles appear in segmental arrangement. Pain and paresthesia are typical zoster symptoms. Complications like bacterial superinfections, vasculopathy, paresis, and oculopathy may occur. During pregnancy herpes zoster is athreat for mother and child. Among elderly patients, cardiovascular risk is increased during the first week of herpes zoster infection. Postherpetic neuropathy is feared. Diagnosis can be made clinically and by the use of polymerase chain reaction. First-line treatment is systemic antiviral drug therapy with either acyclovir or brivudine. Adjuvant therapies consist of pain management and topical treatment.
