Population-based HIV Impact Assessments (PHIA)

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 counselling 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.
