Global-level data are cross-validated and reconciled with data collected by international partners, including bilateral and multilateral organizations which have committed to reporting on these indicators such as the Global Fund to Fight AIDS, Tuberculosis and Malaria, and the President’s Emergency Plan for AIDS Relief (PEPFAR).
