Management of non-genital herpes simplex virus infections in immunocompetent patients.

Non-genital herpes simplex virus in immunocompetent hosts causes a variety of primary infections--gingivostomatitis, keratoconjunctivitis, herpetic whitlow, and encephalomyelitis. Recurrent infections with orolabialis are very common, but are usually mild and self-limiting. Cutaneous complications of herpes simplex virus infections include eczema herpeticum and erytherma multiforme. Systemic treatment with acyclovir is indicated in encephalomyelitis, progressive eczema herpeticum, and frequent severe erythema multiforme. Chronic, suppressive acyclovir treatment may be helpful in severe recurrent infections or those complicated by erythema multiforme/dissemination. Many primary and recurrent infections can be treated with simple topical therapy to control secondary infection. There is no evidence that systemic treatment affects viral latency or recurrent infections following discontinuation of treatment.
