India's TB Burden and Challenges

Examination-Focused Notes on Tuberculosis in India

Current Statistics:

• TB Cases in India (2024): Approximately 27.1 lakh diagnosed cases; 3 lakh deaths.
• Global TB Statistics: In 2024, acknowledged 10.7 million infections and 1.23 million deaths globally.
• India's Contribution: Accounts for 8.8% of the global gap between estimated and diagnosed cases, following Indonesia at 10%.

Government Target:

• Elimination Goal: Prime Minister Narendra Modi announced the target to eliminate TB by 2025, five years ahead of the global objective.
• WHO End TB Strategy: Aims for 80% decline in new TB cases and 90% decline in TB deaths by 2030 compared to 2015.

Progress Metrics:

• Reduction Rates (2015-2024):
  • New cases: 21% reduction.
  • TB-related deaths: 28% reduction.
• Global vs. India Performance:
  • India has met half of the global targets set for 2020, achieving a 20% reduction in cases and a 35% reduction in deaths.

Treatment Coverage:

• Current Coverage: 92% treatment coverage in 2024, up from 85% in 2023, indicating improvements in access and diagnostics.
• Innovative Approaches: Introduction of the BPaL regimen, reducing treatment duration for drug-resistant TB from 18–24 months to 6 months.

Challenges:

• Drug Resistance Prevalence:
  • India contributes to nearly one-third of global drug-resistant TB cases.
  • In 2024, 12.63% were previously treated TB patients, with 3.64% of new cases classified as drug-resistant.
• Impact of COVID-19: Resource diversion during the pandemic has hindered treatment continuity.
• Existing Gaps: Limited availability of childhood TB preparations and preventive treatments for high-risk individuals.

Recent Initiatives:

• Active Screening Campaigns: In a 100-day campaign, over 19 crore individuals screened, resulting in 24.5 lakh detections (including 8.61 lakh asymptomatic cases).
• Technology Utilization: Use of AI-enabled handheld X-ray devices for community screening to enhance early detection.

Economic and Health Impact:

• Diabetes Correlation: Approximately 3.2 lakh TB cases in 2024 could be linked to diabetes prevalence.
• Treatment Success Rate: A 90% success rate for 2023 treatment initiators, higher than the global average of 88%.

These notes summarize significant data regarding tuberculosis in India, highlighting the current situation, government goals, treatment advancements, challenges, and the impact of recent health innovations. Understanding these points is crucial for grasping the public health landscape surrounding TB in India and the ongoing efforts to combat this infectious disease.
