Cutaneous viral infections: herpes simplex and varicella-zoster

Herpes simplex and varicella-zoster infections of the skin are commonly seen in primary care practice. For the patient to be managed most effectively, clinical diagnoses must be accurately made and supported by laboratory confirmation using the Tzanck smear and/or viral culture. Topical therapy and systemic acyclovir can be of help to most patients with these infections.
