Leveraging Global Fund’s investments to expand innovative public-private provider engagement in TB

BACKGROUNDTB remains a significant global health threat, claiming 1. 3 million lives annually. The COVID-19 pandemic disrupted progress in the global TB response. Most patients with TB initially seek care from private providers, whereas only a small proportion are engaged by national programmes. The Global Fund is the major international source of funding for TB responses and supports the scale-up of innovative private-public mix (PPM) models in TB. METHODSWe collected programmatic and financial data on TB from 11 priority countries implementing PPM activities. Country examples and trends in the budget of Global Fund grants were analysed. RESULTSThese countries account for 60% of the global TB burden and Global Fund TB portfolio. PPM contributed 29% of national TB notifications in 2022 (range: 8% to 49%). During 2021–2023, US1. 4 billion was allocated for TB and US155 million (11%) for PPM, while PPM contributed to 35% of national TB notification targets. PPM budgets increased over time from US43 million (2002 to 2014) to US129 million (2024 to 2026). CONCLUSIONThe Global Fund’s investments facilitated the expansion of innovative PPM models, improved access, and enhanced TB responses. Our indicative analysis underscores the need for evidence-based planning, collaboration, and increased domestic investment to accelerate the end of TB.
