    Area of Science:

    • Virology
    • Public Health
    • Epidemiology

    Background:

    • Accumulating evidence supports antiretroviral postexposure therapy (ART) since 1995-1997.
    • Data from vertical transmission studies and animal models reinforce ART efficacy.
    • Guidelines exist for occupational postexposure prophylaxis, but nonoccupational use is debated.

    Purpose of the Study:

    • To review the evidence supporting antiretroviral postexposure therapy.
    • To highlight the ongoing debate regarding nonoccupational postexposure prophylaxis.

    Main Methods:

    • Review of international case-control studies.
    • Analysis of vertical transmission data (zidovudine, nevirapine).
    • Inclusion of animal model data.

    Main Results:

    • Substantial evidence supports ART for HIV prevention postexposure.
    • Established guidelines for occupational prophylaxis.
    • Significant controversy persists regarding nonoccupational prophylaxis.

    Conclusions:

    • Antiretroviral therapy is a viable option for postexposure prophylaxis.
    • Further research and consensus are needed for nonoccupational ART guidelines.
