## Global TB Incidence **Key Point:** The WHO Global TB Report (2023) estimates the global TB incidence at approximately 130 per 100,000 population, translating to roughly 10.6 million TB cases annually worldwide. **High-Yield:** This figure represents a slow but steady decline from peak incidence rates in the 1990s, though progress remains insufficient to meet WHO End TB targets. India, Indonesia, and the Philippines account for nearly half of all TB cases globally. **Clinical Pearl:** Understanding global epidemiology is critical for contextualizing India's TB burden—India accounts for approximately 27% of the global TB disease burden, with an estimated incidence of 199 per 100,000 population (higher than global average). ## Regional Variations | Region | Estimated Incidence (per 100,000) | Key Feature | |--------|-----------------------------------|-------------| | Sub-Saharan Africa | ~220 | Highest incidence globally | | South-East Asia | ~170 | Largest absolute case numbers | | Eastern Mediterranean | ~90 | Moderate burden | | Americas | ~30 | Lowest incidence | | Europe | ~20 | Very low incidence | **Mnemonic:** **GAIT** = Global Average Incidence Trend - **G**lobal ~130 per 100,000 - **A**frica highest (~220) - **I**ndia ~199 (27% global burden) - **T**rend declining but slow
