Genital herpes is a chronic, life-long viral infection. Two types of HSV can cause genital herpes: HSV-1 and HSV-2. Most cases of recurrent genital herpes are caused by HSV-2, and approximately 50 million persons in the United States are infected with this type of genital herpes . Most persons infected with HSV-2 have not had the condition diagnosed. Many such persons have mild or unrecognized infections but shed virus intermittently in the anogenital area. As a result, most genital herpes infections are transmitted by persons unaware that they have the infection or who are asymptomatic when transmission occurs. Management of genital HSV should address the chronic nature of the disease rather than focusing solely on treatment of acute episodes of genital lesions. The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. In sub-Saharan Africa, the region hardest hit by the HIV-1 epidemic, HSV-2 prevalences of 30-50% have been seen in the general population with prevalence up to 90% in infected with HIV-1. Listing a study does not mean it has been evaluated by the U. HSV-2 is common in those with, or at risk for, HIV-1 infection, and HSV-2 reactivation increases HIV-1 acquisition and infectiousness. Sexual transmission is responsible for the vast majority of HIV-1 infections among adults worldwide. Recent studies have shown that suppression of HSV-2 has a sustained effect on lowering HIV-1 levels in blood plasma. New data have raised the question whether higher doses of HSV-2 suppressive therapy might be more effective at suppressing HIV-1 levels. Mugwanya K, Baeten JM, Mugo NR, Irungu E, Ngure K, Celum C. Acyclovir and valacyclovir, chosen for use in this study, are safe and effective treatments for decreasing the frequency of HSV-2 reactivation and shedding. High-dose valacyclovir HSV-2 suppression results in greater reduction in plasma HIV-1 levels compared with standard dose acyclovir among HIV-1/HSV-2 coinfected persons: a randomized, crossover trial. The standard dose of acyclovir is 400 mg twice a day. Changes in plasma human immunodeficiency virus type 1 RNA associated with herpes simplex virus reactivation and suppression.

Acyclovir pills had been in use from 1991 and enjoying the status of a first-of-its-kind antiviral drug for genital herpes treatment, until Valtrex was approved by the US Food and Drug Administration (FDA) 4 years later in 1995.

Nongenital herpes simplex virus type 1 is a common infection usually transmitted during childhood via nonsexual contact. Most of these infections involve the oral mucosa or lips (herpes labialis). The diagnosis of an infection with herpes simplex virus type 1 is usually made by the appearance of the lesions (grouped vesicles or ulcers on an erythematous base) and patient history. However, if uncertain, the diagnosis of herpes labialis can be made by viral culture, polymerase chain reaction, serology, direct fluorescent antibody testing, or Tzanck test. Other nonoral herpes simplex virus type 1 infections include herpetic keratitis, herpetic whitlow, herpes gladiatorum, and herpetic sycosis of the beard area. The differential diagnosis of nongenital herpes simplex virus infection includes aphthous ulcers, acute paronychia, varicellazoster virus infection, herpangina, herpes gestationis (pemphigoid gestationis), pemphigus vulgaris, and Behçet syndrome.
