About PHIA data

Since 2014, the Population-based HIV Impact Assessment (PHIA) Project has conducted nationally representative surveys to capture the state of the HIV epidemic in the most-affected countries. This effort is led by the Ministry of Health in each participating country and funded by the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) through the U.S. Centers for Disease Control and Prevention (CDC) with technical support from ICAP at Columbia University. The PHIA Project embraces strong and effective partnerships to change the course of the HIV epidemic.

The PHIA Project consists of cross-sectional, HIV-focused household surveys to assess the current status and effectiveness of national programs in reaching HIV epidemic control. Each survey offers participants household-based HIV counseling and testing with immediate return of HIV test results conducted by trained survey staff, with subsequent return of additional HIV-related test results. The surveys also ask questions about access to preventive care and treatment services for adolescents and adults (15+) and children (0-14, if applicable). Survey results released to date measured national and regional progress toward UNAIDS’ 90-90-90 and 95-95-95 targets and guide HIV policy and funding priorities as countries strive for epidemic control.

ICAP provides technical assistance at the national level to strengthen data collection systems, enhance laboratory infrastructure, and build capacity to design and conduct PHIA surveys, and analyze PHIA data in each country. The PHIA Project builds on ICAP’s expertise in data collection and management and lab-based measurement of HIV.

The data site provides hands-on access to public data sets and visualization tools resulting from surveys, such as the ability to create charts, graphs, and maps. These tools are both an essential component of the decision-making process of policymakers and program planners and a crucial resource for global health research in HIV.
