Herpes simplex virus infection clinical presentation

Herpes simplex viruses (HSV) types 1 and 2 cause significant morbidity in patients with AIDS. Seropositivity for HSV is widespread among adults with AIDS, and clinical disease usually is the result of reactivation of latent virus. The manifestations of HSV disease observed in persons with AIDS include orolabial, genital, and anorectal mucocutaneous disease esophagitis and less commonly, encephalitis. Ulcerative HSV lesions present for longer than 1 month in an individual with laboratory evidence for HIV infection or no other apparent cause for immunodeficiency are considered an AIDS-defining condition.
