Number of people developing TB

The total of 10.7 million (95% UI: 9.9–11.5 million) in 2024 was a small (1%) reduction from 10.8 million (95% UI: 10.0–11.6 million) in 2023. It remained above the level of 10.3  million (95% UI: 9.6– 11.0 million) in 2020. The 30 high TB burden countries4 accounted for 87% of all estimated incident cases worldwide, with eight of these countries  accounting for two thirds (67%) of the global total: India (25%), Indonesia (10%), the Philippines (6.8%), China (6.5%), Pakistan (6.3%), Nigeria (4.8%), the Democratic Republic of the Congo (3.9%) and Bangladesh (3.6%). The top five countries accounted for 55% of the global total.

1. India’s Global Position

  • India accounts for 25% of the global TB burden — the highest share of any country in the world.
  • Together with Indonesia, the Philippines, China, Pakistan, Nigeria, the Democratic Republic of the Congo, and Bangladesh, these eight countries account for 67% of global TB cases.
  • India remains among the 30 High TB Burden Countries (HBCs) for 2021–2025, and also appears in the HIV-associated TB and MDR/RR-TB lists.

2. Burden of Disease in India (2024 data)

  • Incidence category: 187 (160–218) new cases per 100,000 population per year (Category 3 – endemic).
  • India contributes roughly 2.68 million (2.5–2.8 million) incident TB cases annually (estimated).
  • TB incidence in India has stabilized compared to 2023 but remains a major contributor to the global total.

3. Case Detection and Notification

  • In 2024, the gap between estimated TB incidence and diagnosed cases remains significant but improving.
  • India notified over 96% of estimated incident TB cases, placing it among the best-performing high-burden countries for case detection (alongside Bangladesh, Brazil, Ethiopia, Kenya, Mozambique, Uganda, and Zambia).
  • Despite progress, India still contributed to 8.8% of the global “missing” TB cases — people who developed TB but were not officially diagnosed or reported.

4. Drug-Resistant TB (MDR/RR-TB)

  • India is the largest contributor to the global MDR/RR-TB burden, accounting for 32% of global MDR/RR-TB cases in 2024.
  • Estimated proportion of MDR/RR-TB among new TB cases: ~3.2%, a decrease from 4.7% (95% UI: 3.5–6.0%) in 2015 worldwide.
  • Among previously treated cases, MDR/RR-TB prevalence is ~16%, This was down from 19% (95% UI: 10–28%) in 2015., indicating ongoing transmission and treatment challenges.
  • India, China, the Philippines, and the Russian Federation together make up over 50% of global MDR/RR-TB cases.
  • ines (7.1%) and the Russian Federation (6.7%) (Fig. 8). The highest proportions of people with TB who had MDR/RR-TB (>50% of previously treated cases in 2023) were found in Eastern Europe and Central Asia.

5. TB Mortality in India

  • Globally in 2024, TB caused an estimated 1.23 million, deaths (95% UI: 1.13–1.33 million), including 1.08 million among HIV-negative people (95% UI: 0.99–1.18 million) and 150 000 among people with HIV (95% UI: 120 000– 183  000).1 This total was down from 1.27  million (95% UI: 1.17–1.38  million) in 2023, 1.42  million (95% UI: 1.29–1.55  million) in 2019 (pre-pandemic) and a 42% reduction from 2.13 million (95% UI: 1.91–2.35 million) in 2010. The case fatality rate was 11.5%.
  • India remains among the countries with the highest number of TB deaths , accounting for 28% of deaths globally, though mortality continues to decline.
  • Updated cause-of-death data from India’s Sample Registration System (SRS) 2020 and 2022 were incorporated into WHO’s dynamic modeling for TB incidence and mortality in 2025.
  • Despite the decline, TB remains one of the leading causes of death from infectious disease in India.

6. TB and HIV Co-infection

  • India continues to report HIV-TB co-infection but at relatively low levels compared with African countries.
  • High ART (antiretroviral therapy) coverage among HIV-TB co-infected patients (around 90% globally in 2024) contributes to better outcomes.
  • Deaths from TB among people with HIV have been declining for many years and by 2024 had fallen 76% compared with 2010 worldwide.

7. Treatment Success and Outcomes

  • Treatment success rate (drug-susceptible TB) in India is around 90 %, consistent with the global average.
  • Expansion of rapid diagnostics and shorter, all-oral MDR-TB regimens has improved outcomes since 2023.
  • Five countries accounted for about 60% of the gap between the estimated global number of people who developed MDR/RR-TB in 2024 (incident cases of MDR/ RR-TB) and the global number of people enrolled on treatment in 2024. Listed in order of their share of the global gap, these countries were India (33%), the Philippines (9.3%), Indonesia (7.3%), China (6.1%) and Pakistan (4.1%).

8. TB Funding and Health System Context

  • India, as part of the BRICS group (Brazil, Russia, India, China, South Africa), funds nearly all TB activities domestically, with 97 % of TB spending coming from national resources.
  • This domestic funding has insulated India’s TB program from global donor funding cuts in 2025 that affected many low-income countries.
  • The National TB Elimination Programme (NTEP) continues to drive screening, notification, and treatment expansion through both public and private sectors.
  • Of the 30 high TB burden countries, estimates of the percentage of the population facing catastrophic health expenditures are particularly high (≥15% of the population) for Angola, Bangladesh, China, India, Nigeria, Sierra Leone and Uganda.

9. Data Systems and Research

  • India maintains one of the most robust TB surveillance systems globally.
  • National TB Inventory Study (2019–2021) and National Drug Resistance Surveys (2016, 2024) contribute to WHO’s global modeling.
  • India’s surveillance incorporates mortality data (SRS), inventory studies, and prevalence data for comprehensive disease modeling.

10. Progress Toward End TB Strategy Goals

  • Among the 30 high TB burden countries, most made progress in service coverage between 2000 and 2019. The largest gains in absolute terms (+30 index points or more) were in China, India, Myanmar, Thailand and Viet  Nam.
  • End TB Milestone (2025) targets:
    • 50% reduction in incidence and 75% reduction in deaths (relative to 2015).
  • India has not yet met these milestones but shows steady progress in incidence reduction and improved detection.
  • Key achievements:
    • Enhanced access to rapid diagnostics (GeneXpert, Truenat).
    • Shorter all-oral MDR-TB regimens introduced.
    • Integration of TB-HIV services and nutrition support (Nikshay Poshan Yojana).

11. Future Outlook

  • WHO notes India’s central role in global TB control, emphasizing:
    • Continued investment in TB research and vaccines.
    • Strengthened surveillance and cause-of-death reporting.
    • Sustained domestic funding despite shrinking donor aid.
  • India’s dynamic model updates (2025) will guide new global TB burden estimates for 2026–2030.
