Building a virtual community of practice – The evolution of the TBPPM learning network, India chapter

India's National Tuberculosis (TB) Elimination Program strategically involves private providers to achieve its 2025 goal of ending TB. The government's patient-provider support agency scheme (PPSA) aims to expand the Public-Private Mix (PPM) strategy using domestic resources, though challenges persist in cross-learning and documentation. The TB Public Private Mix Learning Network (TBPPM-LN) launched its India chapter in 2021, connecting PPM stakeholders virtually. With 600 + members, TBPPM-India, acting as a digital Community of Practice, is pivotal in fostering a learning culture, leading knowledge-sharing initiatives, and disseminating TBPPM field innovations, contributing significantly to India's intensified efforts against TB.
