Recently, there has been debate about the role of concurrent partnerships in driving the transmission of HIV, particularly in Southern Africa, where HIV prevalence is up to 25 % in many heterosexual populations and where evidence from sexual behavior surveys also suggests high levels of male concurrency. While mathematical modeling studies have shown that concurrency has the potential to enhance the speed at which HIV spreads in a population, empirical studies up to now have failed to provide conclusive evidence supportive of these effects. Here we discuss some reasons for the apparent discrepancy between theoretical and empirical studies.

Though couples' voluntary HIV counseling and testing (CVCT) is an effective, well-studied intervention in Africa, <1% of couples have been jointly tested.
Methods: We conducted cross-sectional household surveys in Kigali, Rwanda (n = 600) and Lusaka, Zambia (n = 603) to ascertain knowledge, perceptions, and barriers to use of CVCT.
Introduction: The paper reviews progress in addressing the HIV epidemic and questions whether at the midway mark to the conclusion of the Millennium Development Goal set for 2015, the goal number 6 of halting and reversing the HIV epidemic will be reached.
Methods: Fourteen 2008 United Nations General Assembly Special Session on HIV/AIDS country progress reports and 18 country reports on Universal Access 2009 were analyzed. Data on national HIV strategic plans was also provided by 18 countries that participated in the regional training on costed national strategic plans 15-16 September, in Bangkok in 2008.
