Maximizing Impact and Return on Investments in STD/HIV Prevention Programs David Wilson, Nicole Fraser, Marelize Gorgens and Zukhra Shaabdullaeva Global HIV/AIDS Program The World Bank 15 July, 2013 IUSTI Vienna

Estimated national HIV incidence encouraging Measured sub- national HIV incidence worrying The end of AIDS?

Estimated national incidence declines  Estimated national HIV incidence fell by 20%  39 countries (23 African) - declines > 25% UNAIDS, 2012

Concentrated epidemics – MSM Why worry? Proven interventions? Achieve with full implementation? Actual implementation? Investing smarter and implementing better?

Concentrated epidemics – MSM Why worry – MSM HIV rates 13.5-fold higher 20% UNAIDS, 2012

Concentrated epidemics – MSM Proven interventions? Despite developed world successes, few developing country MSM programs have demonstrably reduced HIV incidence PREP reduced HIV among MSM by 44% (90% among fully adherent) but we don’t even reach MSM in most developing countries with information and condoms In developing countries, scarcely know how to reach hidden MSM, reduce stigma, deliver at scale and change policy Still need to navigate between southern unwillingness to address male-male sexuality and northern temptation to frame response within western constructs

Concentrated epidemics – MSM Implementation and coverage limited 70% very low or don’t report 90% of funding international LMIC reliant on external funding 70% very low or no report UNAIDS, 2012

Concentrated epidemics – MSM Few reached by HIV prevention services

Concentrated epidemics – IDU Implementation and coverage limited 86% low coverage or no report UNAIDS, 2012

Concentrated epidemics – IDU Low access to basic services 90% 92% 85% Million IHRA, 2012

Generalized epidemics - VMMC Actual implementation is seriously off-target PEPFAR, 2013 Total

Generalized epidemics - TAsP Do we have proven approaches? TAsP clinical trial efficacy 96%+ TAsP real world effectiveness lower? – Infection 34% lower in area with 30%-40% ART coverage (the effect saturation point) than area with <10% coverage in KZN (Tanser et al, 2013) – Infection 26% lower in discordant couples in China - for transfusion or sexually infected but not IDU infected indexes (Jia, 2012) – No difference in discordant couples in Uganda (Birungi et al. 2013) – HIV infections continue to rise in highly treated MSM communities in developed countries (Wilson et al, 2012) – With ~85% on ART at CD350, Swaziland has measured HIV incidence of 2.4% on top of 26% adult prevalence (SHIMS, 2013)

Generalized epidemics - ART What is actual implementation like? US treatment cascade - 28% virally suppressed

Generalized epidemics – Financial incentives Do we have proven approaches? Three World Bank RCTs show financial incentives reduce STI/HIV transmission – In Tanzania, people offered up to $60 each annually to stay STI- free had 25 percent lower STI prevalence (De Walque et al 2012) – In Malawi, girls and parents offered up to $15 monthly to stay in school had 60% lower HIV prevalence - whether they stayed in school or not (Ozler et al, 2012) – In Lesotho, adolescents offered a lottery ticket to win up to $50 or $100 every four months if they stayed STI and HIV-free had a 25% lower HIV incidence - 33% lower among girls and 31% in the $100 arm (De Walque et al 2012)

Watts, % reduction in HIV risk

Post-MDG High Level Panel Report Word Cloud Wagstaff, 2013

Conclusion At best flat financing and competing priorities With existing implementation and rate of expansion, we are likely to prevent less than half of new infections in next decade With full implementation of interventions, we could prevent over half of new infections Bridging the gap between full and actual implementation means moving from age of advocacy to era of implementation - intelligent, inquiring, critical, tailored, targeted, painstaking implementation Ending AIDS requires more and better tools
