USAID implementing partners voluntarily submitted over 145 cases to this Global Call for HSS Cases website. Eligible activities included those funded by USAID Global Health Bureau, bilateral mission, or regional operating unit budgets for programs in USAID's 24 priority countries for Ending Preventable Child and Maternal Deaths (EPCMD) countries and the PEPFAR AIDS-Free Generation (AFG) priority countries. The Global Health Bureau's OHS review panels and senior leadership evaluated the cases, using objective criteria to determine which cases demonstrated compelling evidence for sustainably improving country health system performance and/or health impact.
