The Global TB Caucus is an international network of over 2500 parliamentarians who work at the national, regional, and global levels towards ending the TB epidemic. Behind COVID-19, TB is the world’s leading infectious killer, yet is a curable and preventable disease. We therefore believe that the primary obstacle to ending the TB epidemic is the lack of political will. To combat this, Caucus members – national parliamentarians – work with civil society, regional and global bodies, and their governments to advocate for increased resources and improved policies dedicated to TB.
