HIV serodiscordant couples, where one partner is HIV positive and the other is HIV negative, are increasingly being recognized as a priority for HIV prevention in developing countries (Joint United Nations Programme on HIV/AIDS [UNAIDS] 2008).
Recent studies have estimated that in several sub- Saharan African countries, approximately two-thirds of infected couples are serodiscordant couples (de Walque, 2007). Developing effective HIV prevention interventions that target serodiscordant couples could potentially contribute to reducing HIV transmission in many countries. Moreover, provision of services to serodiscordant couples to help them manage their status is an essential component of comprehensive HIV responses.
This brief provides a summary of prevention interventions that are effective or showing promise in developing countries toward reducing HIV sexual transmission risk within serodiscordant cohabiting heterosexual or married couples.
