Signs herpes outbreak is coming

Individual primers on more than 100 skin diseases including initial evaluation, treatment options, and clinical case studies.
Viral infections by herpes simplex (HSV) typically occur in two locations: the orofacial (usually type I) and genital (usually type II).
Acyclovir is almost always the first-line treatment given to individuals with healthy immune systems; in immunosuppressed individuals (especially HIV-infected persons), acyclovir resistance is a concern and should always be considered if a patient does not respond to acyclovir therapy. Both orofacial and genital herpes may be recurrent; in frequent cases, chronic viral suppression with systemic acyclovir may be indicated. Herpes simplex may result in painful or burning crusted grouped vesicles near the mouth or nares, often recurrent in the same location. Impetigo contagiosum commonly involves the perioral and perinasal areas of the face and are typified by honey-colored crusting.
Herpes zoster is caused by dermatomal reactivation of varicella virus and can also result in grouped clear fluid-to-pus-filled vesicles on an erythematous-to-hemorrhagic base.
Aphthous ulcers are typically recurrent ulcers that affect the mouth or genitalia, and may occur sporadically or in the context of a systemic disease (such as inflammatory bowel disease). Perform viral direct immunofluorescence assay (DFA) and culture to confirm diagnosis of HSV.
For the immunosuppressed, topical acyclovir 5% ointment (such as Zovirax ointment) 4-5x day may accelerate healing. In recurrent cases, treatment must be begun at the earliest prodrome and be patient initiated.


Failure to adjust the acyclovir dose for decreased renal function can lead to side effects, especially when high-dose intravenous acyclovir is given. Be alert for the genital ulcer containing multiple pathogens and evaluate patients with genital HSV for other STDs. Rarely acyclovir-resistant mutants of HSV may cause chronic genital or oral ulcers in immunosuppressed (usually HIV-infected) patients. For management of recurrent herpes, not suppressed by standard suppressive therapy, especially in an immunocompromised or immunosuppressed patient.
Prescription for valacyclovir or acyclovir given as abortive therapy for future recurrences (dose valacyclovir 2 g p.o.

Some recurrences of orofacial herpes may be triggered by sun exposure, and photoprotection may be an important preventive measure. Grouped (herpetiform) pustular lesions resulting in erosions with scalloped borders are suggestive of herpes. They are marked by a small, often painful pustule with a bright erythematous (but typically not purpuric) border that may resolve after a phase of ulceration. Oral and topical acyclovir do not significantly shorten the course in most patients once lesions are present.


Monitor renal function during intravenous acyclovir therapy and ensure adequate hydration to prevent renal impairment.
HSV II is the most common cause of genital ulcer disease in the United States, and accurate, confirmed diagnosis is essential.

Serologic testing is in general not useful, except in the primary disease with acute and convalescent titers.
The results of serologic testing are usually not available for days, and are only retrospectively of benefit in the rare case.
