The Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) aims to support the use of implementation science approaches. AHISA aims to enhance the effective use of evidence and help overcome implementation challenges related to prevention, screening and treatment of HIV among adolescents in sub-Saharan Africa by catalyzing collaboration and communication among NIH-funded implementation scientists, program implementers and policymakers.


The goals of the Alliance are to:
  • Provide a platform for cross-fertilization and exchange of ideas and information among implementation scientists and other stakeholders focusing on different aspects of HIV in adolescents;
  • Enable the research to be better informed by programmatic challenges and questions;
  • Inform policymakers of promising evidence and encourage use of the data in decision making; and
  • Extend the reach and impact of implementation science related to adolescent HIV prevention and treatment.

AHISA is made up of 26 teams across 11 countries in sub-Saharan Africa. Each team is composed of NIH-funded scientists conducting relevant implementation research; in-country partners including PEPFAR in-country staff, key in-country government representatives, in-country research collaborators, and other stakeholders; and youth. The Alliance is led by members of CGHS and driven by a steering committee of experts.
