The Stop TB Partnership is leading tuberculosis (TB) control efforts worldwide through its various global working groups coordinated by the Stop TB Coordinating Board. DOTS is the internationally recommended strategy for TB control. The DOTS Expansion Working Group (DEWG) represents the national TB programmes (NTPs) of 22 high TB-burden countries (HBCs) that bear 80% of the global TB burden, international technical partners, and donor agencies engaged in global TB control. The DEWG is hosted by WHO.
