The PHIA Project
For the global community to achieve its HIV treatment goals, data are needed on the impact of country-level programs. The PHIA Project measures the reach and impact of HIV programs in PEPFAR-supported countries through national surveys. Each population-based HIV impact assessment (PHIA) survey offers household-based HIV counseling and testing conducted by trained survey staff, with return of results. The surveys also ask questions about access to preventive care and treatment services for adults and children. The results measure national and regional progress toward UNAIDS' 90-90-90 goals and guide policy and funding priorities. This PEPFAR-funded project is led by ICAP at Columbia University in partnership with the US Centers for Disease Control and Prevention (CDC), and the Ministry of Health in each country. Below is a dashboard with information on ongoing PHIA surveys.
