Additional information HIV-2 is closely related to HIV-1 regarding nucleic acid sequence and clinical disease. HIV-2 is endemic to West Aftrica with nearly all cases in the United States identified in citizens or travelers from West Africa. Rarely, HIV-1 Western blot indeterminate results may be due to HIV-2 infection in a patient who has been exposed to HIV-2. The Western blot is useful to confirm repeatedly reactive EIA results.
