Although external financing for tuberculosis control has substantially increased, funding shortfalls remain. Global financing architecture is complex because of several streams of external investments, and countries struggle to manage this complexity with restricted stewardship capacity. Public-private approaches in the countries studied, especially in Bangladesh have helped to expand service coverage, improve outcomes, and address gaps in human resources. Public-private mix is a robust model for tuberculosis control and care, but such approaches still need to be effectively scaled up in India, since most health care is delivered in the private sector, and public-private approaches remain woefully inadequate in Africa.
