Answer

The possibility of human immunodeficiency virus (HIV)–2 infection should be entertained in patients with the following risk factors: [50, 51]

  • Illness characteristic of HIV infection despite negative HIV-1 test result

  • West African origin

  • Sex partners or needle-sharing partners of a person known to be infected with HIV-2 or who is not infected but is from an HIV-2–endemic area

  • Children born to women with HIV-2 or who have risk factors for HIV-2 infection

  • Persons who have participated in a HIV-vaccine trial or have receive blood products or a nonsterile injection in HIV-2–endemic areas

  • People with unusual HIV-1 Western blot indeterminate patterns (Gag plus Pol reactive bands without Env reactive bands)
