Skin Infections and Outpatient Burn Management: Fungal and Viral Skin Infections.

Fungal and viral skin infections are common and typically are managed by family physicians. The fungal skin infections commonly seen in family practice include the various forms of tinea: tinea corporis, tinea gladiatorum, tinea cruris, tinea pedis, tinea capitis, and tinea unguium (eg, onychomycosis). Common viral skin infections include herpes simplex virus infection, herpes zoster, cutaneous and genital warts, and molluscum contagiosum. Many fungal and viral skin infections have a classic appearance but variations and atypical manifestations can make patients with these conditions difficult to diagnose definitively. Confirmatory testing often is not required. In complex cases with atypical features, microscopy, culture, or blood tests can help in making a diagnosis. For some infections, treatment may be initiated before confirmatory test results are received. Most fungal skin infections can be managed effectively with topical antifungals. Tinea capitis and onychomycosis should be managed with oral drugs. Oral antiviral drugs are used to manage most viral skin infections but dosages vary based on the condition and phase of the infectious process. Cutaneous warts typically are managed with salicylic acid and/or cryotherapy.
