RESUMEN

Southern Africa is the region worst affected by HIV in the world and accounts for one third of the global burden of HIV. Achieving the UNAIDS 90-90-90 target by 2020 and ending the AIDS epidemic by 2030 depend on success in this region. We review epidemiological trends in each country in southern Africa with respect to the prevalence, incidence, mortality, coverage of anti-retroviral therapy (ART) and TB notification rates, to better understand progress in controlling HIV and TB and to determine what needs to be done to reach the UNAIDS targets. Significant progress has been made in controlling HIV. In all countries in the region, the prevalence of HIV in people not on ART, the incidence of HIV, AIDS-related mortality and, in most countries, TB notification rates, are falling. In some countries, the risk of infection began to fall before biomedical interventions such as ART became widely available as a result of effective prevention measures or people's awareness of, and response to, the epidemic but the reasons for these declines remain uncertain. Some countries have achieved better levels of ART coverage than others, but all are in a position to reach the 2020 and 2030 targets if they accelerate the roll-out of ART and of targeted prevention efforts. Achieving the HIV treatment targets will further reduce the incidence of HIV-related TB, but efforts to control TB in HIV-negative people must be improved and strengthened.

RESUMEN

BACKGROUND: In 2012, South Africa set a goal of circumcising 4.3 million men ages 15-49 by 2016. By the end of March 2014, 1.9 million men had received voluntary medical male circumcision (VMMC). In an effort to accelerate progress, South Africa undertook a modeling exercise to determine whether circumcising specific client age groups or geographic locations would be particularly impactful or cost-effective. Results will inform South Africa's efforts to develop a national strategy and operational plan for VMMC. METHODS AND FINDINGS: The study team populated the Decision Makers' Program Planning Tool, Version 2.0 (DMPPT 2.0) with HIV incidence projections from the Spectrum/AIDS Impact Module (AIM), as well as national and provincial population and HIV prevalence estimates. We derived baseline circumcision rates from the 2012 South African National HIV Prevalence, Incidence and Behaviour Survey. The model showed that circumcising men ages 20-34 offers the most immediate impact on HIV incidence and requires the fewest circumcisions per HIV infection averted. The greatest impact over a 15-year period is achieved by circumcising men ages 15-24. When the model assumes a unit cost increase with client age, men ages 15-29 emerge as the most cost-effective group. When we assume a constant cost for all ages, the most cost-effective age range is 15-34 years. Geographically, the program is cost saving in all provinces; differences in the VMMC program's cost-effectiveness across provinces were obscured by uncertainty in HIV incidence projections. CONCLUSION: The VMMC program's impact and cost-effectiveness vary by age-targeting strategy. A strategy focusing on men ages 15-34 will maximize program benefits. However, because clients older than 25 access VMMC services at low rates, South Africa could consider promoting demand among men ages 25-34, without denying services to those in other age groups. Uncertainty in the provincial estimates makes them insufficient to support geographic targeting.

RESUMEN

BACKGROUND: Concerted efforts and substantial financial resources have gone toward strengthening national monitoring and evaluation (M&E) systems for HIV programs. This article explores whether those investments have made a difference in terms of data availability, quality and use for assessing whether national programs are on track to achieve the 2015 Millennium Development Goal (MDG) of halting and reversing the HIV epidemic. METHODS: Descriptive analyses, including trends, of the National Composite Policy Index data and M&E expenditures were conducted. Global Fund funding continuation assessments were reviewed for concerns related to M&E. Availability of population-based survey data was assessed. RESULTS: There has been a marked increase in the number of countries where the prerequisites for a national HIV M&E system are in place and in human resources devoted to M&E at the national level. However, crucial gaps remain in M&E capacity, available M&E data, and data quality assurance. The extent to which data are used for program improvement is difficult to ascertain. There is a potential threat to sustaining the current momentum in M&E as governments have not committed long-term funding and current M&E-related expenditures are below the minimum needed to make M&E systems fully functional. CONCLUSIONS: There is evidence of rapid scale-up of basic HIV M&E systems, but if M&E is to fulfil its role in guiding optimal use of resources, ensuring effective HIV programs and providing evidence of progress toward the Millennium Development Goal of halting and reversing the HIV epidemic, essential data gaps will need to be filled urgently and those data will need to be used to guide decision making.
