Summary of Prevention of New HIV Infections: Priorities for U.S. Action

Core Content

This report, authored by the CSIS Global Health Policy Center, outlines key priorities for U.S. action on HIV prevention, focusing on the next five years of the President's Emergency Plan for AIDS Relief (PEPFAR). It emphasizes the need for a renewed, evidence-based, and strategically focused approach to HIV prevention in developing countries, where new infections continue to rise despite existing efforts.

The report highlights the importance of PEPFAR as a global leader in HIV prevention and calls for increased investment in research, data collection, and program implementation. It also stresses the necessity of aligning U.S. support with national leadership in partner countries and ensuring that prevention efforts are both effective and sustainable.

Main Recommendations

The following are the key recommendations and principles identified in the report:

1. Capitalize on PEPFAR's Leadership Opportunity

• Clarify prevention as a core PEPFAR issue: Emphasize that prevention is not just a complement to treatment but a central component of the global response.
• Acknowledge the complementarity of prevention and treatment: Highlight the importance of integrating these efforts and exploring new interventions such as male circumcision and pre-exposure prophylaxis (PrEP).
• Build global consensus: Collaborate with international organizations like the Global Fund, WHO, and UNAIDS to align on prevention priorities.
• Support a global stocktaking: Contribute to the 2010 UNGASS Universal Access Summit by assessing global HIV prevention progress.

2. Leverage U.S. Commitments

• Condition support on national performance: Ensure that partner governments commit to effective prevention and support high-risk populations such as men who have sex with men, injecting drug users, and commercial sex workers.
• Develop sustainability strategies: Create accountability mechanisms within PEPFAR’s Partnership Frameworks to ensure long-term success and integration of civil society in national responses.
• Pilot sustainability strategies: Implement these strategies in several countries by FY2011.

3. Link Resources to Need and Support Proven Programs

• Revisit U.S. HIV prevention priorities: Conduct an "audit" of prevention funding and match it with local transmission data.
• Target high-risk populations and regions: Focus on areas and groups with the highest transmission rates, including "prevention for positives" (preventing transmission from known infected individuals).
• Promote combination prevention: Use a variety of evidence-based strategies to address the complex epidemiological and social environment.
• Address gender imbalances: Improve access to family planning services for HIV-positive women and tackle structural barriers that increase women’s vulnerability.
• Harmonize measurement and evaluation: Develop consistent data collection and monitoring methods across PEPFAR and other donors, and ensure that these align with national systems.
• Accept attribution limitations: Recognize that it may not always be possible to attribute outcomes solely to U.S.-funded interventions.

4. Take on Operational Research Challenges

• Incubate innovation: Use PEPFAR’s influence to support new ideas and research in HIV prevention.
• Coordinate research and evaluation: Implement a unified agenda for epidemiological surveillance, operations research, and metrics development.
• Share knowledge globally: Create a system for rapid identification, validation, and dissemination of findings from prevention programs.
• Establish an external advisory group: Bring in expertise from non-governmental organizations to guide key prevention strategies, such as expanding male circumcision programs.

Key Challenges

• Limited data on program efficacy and cost-effectiveness: Many countries lack robust data to measure the true impact of prevention efforts.
• Financial and resource constraints: Host governments often struggle to increase their financial and human resource commitments to HIV prevention.
• Political and structural barriers: Stigma, discrimination, criminalization of high-risk behaviors, and laws that hinder access to services pose significant challenges.
• Need for community mobilization: Strengthening community involvement is essential for sustainable prevention efforts.
• High rates of undiagnosed HIV infections: In sub-Saharan Africa, over 80% of HIV-infected individuals are unaware of their status, which hampers effective prevention.

Case Studies: PEPFAR Experience in Three Countries

Kenya

• HIV prevalence: 7.4%
• PEPFAR investment (FY2008): US$534 million
• Key prevention efforts: Behavior change, prevention of mother-to-child transmission (PMTCT), expanded HIV testing, and male circumcision programs.
• Challenges: High rates of undiagnosed infections, limited government financial commitment, and fragmented programs.
• Progress: PEPFAR supported the development of the third National AIDS Strategic Plan (KNASP III) with a stronger prevention focus.

South Africa

• HIV prevalence: 18%
• PEPFAR investment (FY2008): US$590 million
• Key prevention efforts: Peer education for youth, prevention for positives, and male circumcision.
• Challenges: Inadequate government support, fragmented programs, and limited focus on key drivers of the epidemic.
• Progress: PEPFAR rebalanced its prevention strategy to target the most affected groups, particularly young women.

Vietnam

• HIV prevalence: <0.5%
• PEPFAR investment (FY2008): US$89 million
• Key prevention efforts: Focus on injecting drug users, commercial sex workers, and men who have sex with men.
• Challenges: High rates of undiagnosed infections, limited data on transmission patterns, and the need for more targeted interventions.
• Progress: PEPFAR has contributed to the expansion of prevention programs, but more needs to be done to address the concentrated epidemic.

Conclusion

The report underscores the critical role of PEPFAR in global HIV prevention and calls for a more strategic, data-driven, and community-focused approach. It emphasizes the importance of political will, financial commitment, and operational research in achieving sustainable and effective prevention outcomes. The U.S. must continue to lead in this area, leveraging its resources and partnerships to address the ongoing HIV epidemic.
