The Research Consortium


The GET ON research project has been developed in collaboration with the “Towards 90-90-90” research consortium.

The research consortium fosters operational and clinical research aiming at achieving the UNAIDS 90-90-90 targets and generating evidence on innovative approaches for Lesotho and similar settings. The five institutions that are part of this consortium are the following:

  1. District Health Management Team of Butha-Buthe, Lesotho
  2. Ministry of Health of Lesotho
  3. Swiss Tropical and Public Health Institute, Basel, Switzerland
  4. SolidarMed, Swiss Organization for Health in Africa, Lesotho
  5. Molecular Virology, Department of Biomedicine, University of Basel, Switzerland
