How do concurrent partnerships impact HIV prevention?
Research shows that involvement in multiple concurrent partnerships, known as "sexual networking" or "sexual mixing" is a key driver of HIV transmission, especially having more than one longer-term sexual partner at a time. While there is considerable evidence of condom use for HIV prevention during casual sex encounters, this is less true in longer-term relationships, monogomous or not.
Partner reduction campaigns, such as "Zero Grazing" (Uganda) and "One Love" (9-SADC country campaign) are on the cutting edge of social change communication for HIV prevention in this area. UNAIDS' document Multiple Concurrent Partnerships: Campaign and Communications
, done in collaboration with the Soul City Institute, provides further information and guidance.
