Tracking PEPFAR Impact Toward Global Targets
The U.S. Centers for Disease Control and Prevention (CDC) works with partners including host countries, local implementing partners, faith-based organizations, and other community-based organizations to measure progress towards HIV epidemic control in countries supported by the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR).
The Population-Based HIV Impact Assessments (PHIAs) surveys are an important tool for measuring the impact of HIV treatment and prevention programs in PEPFAR-supported countries. CDC and partners apply analytical insights from PHIAs to make timely adjustments to programs, leading to increased efficiencies and positive outcomes for community members, including people living with HIV.
CDC’s technical expertise and scientific leadership, as well as longstanding relationships with national and regional governments, implementing partners, and host communities, contribute to the success of the collection and analysis of survey data and the rapid implementation of insights towards continuous program improvement.
UNAIDS is leading the charge against HIV/AIDS with the goal of eliminating HIV as a public health threat by 2030. This initiative is aligned with the United Nations Sustainable Development Goals. To attain this goal, UNAIDS set the ambitious but achievable 95-95-95 targets:
- 95-percent of all people living with HIV will know their HIV status
- 95-percent of all people with diagnosed HIV infection will receive sustained antiretroviral treatment (ART)
- 95-percent of all people receiving ART will achieve viral suppression
Prior to 2020, PHIAs tracked progress towards the 90-90-90 goals – which reflect a snapshot of progress at the time of the survey – in sub-Saharan Africa and Haiti. Subsequent surveys now track progress towards the more ambitious 95-95-95 targets.
Joint United Nations Programme on HIV/AIDS (UNAIDS) global targets for HIV epidemic control call for finding and diagnosing people living with HIV and ensuring they receive sustained antiretroviral treatment. Research shows that sustained antiretroviral treatment reduces the amount of HIV in a person’s body – also referred to as viral load – to an undetectable level, that virtually eliminates transmission of the virus to sexual partners.
The PHIAs are led by the Ministry of Health in each participating country, in partnership with the CDC and with support from PEPFAR. Technical and implementation support is provided by partners, including ICAP at Columbia University and the University of Maryland School of Medicine.
Working with Ministries of Health, other U.S. government agencies and technical partners, CDC lends expertise in epidemiology, laboratory science, and data analysis to help partners design and implement PHIAs and rapidly harness the results for program improvement in PEPFAR-supported countries.

PHIA Survey Data Highlights
Data highlights from participating countries’ surveys showing progress toward UNAIDS targets and HIV incidence, prevalence, and viral load suppression. Prior to 2020, PHIAs tracked progress toward 90-90-90 targets – which reflect a snapshot of progress at the time of the survey. Subsequent surveys track progress toward more ambitious 95-95-95 targets.
