According to the CDC, the diagnosis of AIDS constitutes certain opportunistic infections, neoplasms, encephalopathy or wasting syndrome in the presence of HIV infection. In 1993, the CDC expanded the criteria to also include CD4+ T-cell count below 200 cells/p,l in the presence of HIV infection. The most common opportunistic infections includepneumocystis carinii pneumonia, pneumonitis, toxoplasmosis, mycobacterial disease, recurrent herpes simplex virus infection and/or cytomegalovirus infection. Kaposi s sarcoma is the most common form of cancer. HIV-related nervous system diseases include acute septic meningitis, AIDS dementia complex, subacute encephalitis, HIV encephalopathy and CNS opportunistic infections and neoplasm.

Infection with herpes simplex virus type 1 (HSV-1) typically causes diseases of the mouth, face, skin, esophagus, or brain. Herpes simplex virus type 2 (HSV-2) usually causes infections of the genitals, rectum, skin, hands, or meninges. Both cause serious infections in neonates. HSV infection may be a primary one in a naive host, a nonprimary initial one in a host previously infected by other viruses, or the consequence of activation of a latent infection. 

Suggested Alternatives for Differential Diagnosis Other forms of encephalitis (e.g., California, Eastern Equine, St Louis, West Nile, Murray Valley), malaria, dengue fever, meningitis, tuberculosis, typhoid fever, enteroviruses, herpes simplex, and Nipah virus.
