RESUMO
Introduction: In 2004, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), with CDC as a major U.S. government implementing agency, began providing HIV antiretroviral therapy (ART) worldwide. Through suppression of HIV viral load, effective ART reduces morbidity and mortality among persons with HIV infection and prevents vertical and sexual transmission. Methods: To describe program impact, data were analyzed from all PEPFAR programs and from six countries that have conducted nationally representative Population-based HIV Impact Assessment (PHIA) surveys, including PEPFAR programmatic data on the number of persons with HIV infection receiving PEPFAR-supported ART (2004-2022), rates of viral load coverage (the proportion of eligible persons with HIV infection who received a viral load test) and viral load suppression (proportion of persons who received a viral load test with <1,000 HIV copies per mL of blood) (2015-2022), and population viral load suppression rates in six countries that had two PHIA surveys conducted during 2015-2021. To assess health system strengthening, data on workforce and laboratory systems were analyzed. Results: By September 2022, approximately 20 million persons with HIV infection in 54 countries were receiving PEPFAR-supported ART (62% CDC-supported); this number increased 300-fold from the 66,550 reported in September 2004. During 2015-2022, viral load coverage more than tripled, from 24% to 80%, and viral load suppression increased from 80% to 95%. Despite increases in viral load suppression rates and health system strengthening investments, variability exists in viral load coverage among some subpopulations (children aged <10 years, males, pregnant women, men who have sex with men [MSM], persons in prisons and other closed settings [persons in prisons], and transgender persons) and in viral load suppression among other subpopulations (pregnant and breastfeeding women, persons in prisons, and persons aged <20 years). Conclusions and implications for public health practice: Since 2004, PEPFAR has scaled up effective ART to approximately 20 million persons with HIV infection in 54 countries. To eliminate HIV as a global public health threat, achievements must be sustained and expanded to reach all subpopulations. CDC and PEPFAR remain committed to tackling HIV while strengthening public health systems and global health security.

The DREAMS (Determined, Resilient, Empowered, AIDS-Free, Mentored, and Safe) Partnership, a public-private partnership launched by the United States President's Emergency Plan for AIDS Relief (PEPFAR), represents the largest investment in comprehensive HIV prevention for adolescent girls and young women (AGYW) ever made in a single global initiative. This paper describes the evolution of programming over time using the triangulation of multiple data sources to develop and refine an impactful program, as well as to improve efficacy and resource investment. Methods of analysis used to evolve this programming include reviews of literature on behavioral, biomedical and structural interventions, and HIV vulnerability; PEPFAR program data; external implementation science and impact studies;observations from site visits; in-depth reviews of program materials; and inputs from AGYW and other stakeholders. Key program improvements made in response to this real-time data use are described, including the rationale for programmatic changes and the evidence base for continual program refinements. This review emphasizes the importance and process of implementing the most effective combination of structural and biomedical HIV prevention programming, based on the best available science, while also adapting to local context in a way that does not compromise effectiveness or violate core implementation principles. Data from research and evaluation are critical to move the HIV prevention field toward more impactful and efficient programming responsive to the lived realities of AGYW. A central tenant to using these data sources effectively is the inclusion of AGYW in decision-making throughout the planning and implementation of programming.

CONTEXT: Adolescence marks a time when many young people engage in risky behaviors with potential implications for long-term health. Interventions focused on adolescents' parents and other caregivers have the potential to affect adolescents across a variety of risk and health-outcome areas. EVIDENCE ACQUISITION: Community Guide methods were used to evaluate the effectiveness of caregiver-targeted interventions in addressing adolescent risk and protective behaviors and health outcomes. Sixteen studies published during the search period (1966-2007) met review requirements and were included in this review. EVIDENCE SYNTHESIS: Effectiveness was assessed based on changes in whether or not adolescents engaged in specified risk and protective behaviors; frequency of risk and protective behaviors, and health outcomes, also informed the results. Results from qualifying studies provided sufficient evidence that interventions delivered person-to-person (i.e., through some form of direct contact rather than through other forms of contact such as Internet or paper) and designed to modify parenting skills by targeting parents and other caregivers are effective in improving adolescent health. CONCLUSIONS: Interventions delivered to parents and other caregivers affect a cross-cutting array of adolescent risk and protective behaviors to yield improvements in adolescent health. Analysis from this review forms the basis of the recommendation by the Community Preventive Services Task Force presented elsewhere in this issue.

South Africa is experiencing significant changes in patterns of illicit drug use, including increasing injection and non-injection drug use, and the use of drugs by persons engaged in sex work, both of which could further expand the HIV/AIDS epidemic. In 2005, a rapid ethnographic assessment was conducted in Durban, South Africa, to learn more about patterns of drug use and HIV risk behaviors among drug-using, street-based sex workers. Field teams recruited 52 current injection and non-injection drug users for key informant interviews and focus groups, and they conducted mapping and observation in identified high-risk neighborhoods. Key informants were offered free, voluntary counseling and HIV rapid testing. The results of the assessment indicate that in this population, drugs play an organizing role in patterns of daily activities, with sex work closely linked to the buying, selling, and using of drugs. Participants reported using multiple drugs including crack cocaine, heroin, Ecstasy and Mandrax, and their choices were based on their expectations about the functional role and behavioral and pharmacological properties of the drugs. The organization of sex work and patterns of drug use differ by gender, with males exercising more control over daily routines and drug and sexual transactions than females. Activities of female sex workers are subject to considerable control by individual pimps, many of whom also function as landlords and drug dealers. A strong hold over the overlapping economies of drugs and sex work by a few individuals extends to control of the physical and social settings in which sex is exchanged and drugs are sold and used as well as the terms under which sex work is carried out. The potential for accelerated HIV spread is considerable given the evidence of overlapping drug-using and sexual risk behaviors and the mixing patterns across drug and sexual risk networks.
