India’s Fight Against Tuberculosis

Context: On World Tuberculosis Day, President of India highlighted India’s progress under the TB Mukt Bharat Abhiyan, noting a 21% reduction in TB incidence.

• India is currently launching a new 100-day intensified campaign to deepen these gains through Jan Bhagidari (people’s participation) and advanced AI diagnostics.

About India’s Fight Against Tuberculosis:

What is TB?

• Tuberculosis (TB) is a dynamic infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs (Pulmonary TB) but can also attack other parts of the body like the spine, brain, and kidneys (Extra-pulmonary TB). It spreads through the air when an infected person coughs or sneezes.

Types of TB Cases:

• Latent TB: The person has the bacteria in their body, but the immune system keeps it in check. They are not symptomatic and cannot spread the disease.
• Active TB: The bacteria multiply, making the person sick and infectious.
• Asymptomatic TB: A critical focus in 2026; patients who do not show typical symptoms (like persistent cough) but can still spread the infection.
• Drug-Resistant TB (MDR/XDR-TB): Cases where the bacteria do not respond to standard first-line or even second-line antibiotics.

Data/Stats on TB in India:

• Incidence Reduction: India has achieved a 21% reduction in TB incidence since 2015, which is nearly twice the global rate of decline.
• Mortality Decline: There has been a 25% decrease in TB-related deaths in the same period.
• Screening Reach: More than 20 crore people have been screened recently, leading to the detection of over 32 lakh cases.
• The Asymptomatic Burden: National surveys reveal that 50% of TB patients do not show typical symptoms, necessitating proactive AI-based screening.

Initiatives Taken to Eradicate TB:

India Level:

• Ni-kshay Poshan Yojana: Provides ₹500/month nutritional support to every TB patient via DBT.
• Ni-kshay Mitras: A unique Jan Bhagidari initiative where individuals or institutions adopt TB patients to provide nutritional and vocational support.
• AI-Enabled Diagnostics: Deployment of over 3,000 AI-powered handheld X-ray units and Ni-kshay Vahans to reach remote areas.
• 100-Day Intensified Campaign: A multi-ministerial push launched in 2026 to achieve Zero TB at the village and panchayat levels.

Global Level:

• WHO End TB Strategy: A global roadmap aiming for a 95% reduction in deaths and a 90% reduction in incidence by 2035.
• The Global Fund: A multi-billion dollar international financing mechanism to fight AIDS, TB, and Malaria.
• UN High-Level Meeting (UNHLM) Targets: Specific global commitments to put 40 million people on TB treatment.
• Moscow Declaration: A commitment by world leaders to increase multisectoral action and accountability to end TB.

Importance of Eradicating TB:

• Economic Productivity: TB primarily affects the working-age population, leading to massive man-hour losses.

Example: Eradicating TB could save India billions by preventing the catastrophic costs that push families into poverty.

• Health System Resilience: Reducing the TB burden frees up hospital beds and resources for other emerging threats.

Example: The infrastructure built for TB (like molecular testing) was successfully repurposed for the COVID-19 pandemic.

• Social Equity: TB is a disease of poverty, disproportionately affecting marginalized communities.

Example: Successful elimination ensures that migrant workers and slum dwellers have equal access to life-saving healthcare.

• Preventing Antimicrobial Resistance (AMR): Controlling TB prevents the rise of superbugs.

Example: Proper treatment completion stops the mutation of bacteria into deadly MDR-TB strains.

• Demographic Dividend: Ensuring a TB-free youth allows India to harness its full human potential.

Example: Programs like MY Bharat engage youth volunteers to ensure the next generation is free from the stigma of the disease.

Challenges Associated with Eradication:

• The Silent Spread: Asymptomatic cases make traditional passive screening ineffective.

Example: 10.9 lakh asymptomatic cases were only found because India shifted to proactive AI screening.

• Social Stigma: Patients often hide their condition to avoid social isolation or job loss.

Example: Many women in rural areas delay treatment seeking due to the fear of marital or social rejection.

• Treatment Adherence: The TB course is long (6-9 months), and patients often stop once they feel slightly better.

Example: High drop-out rates lead to the development of Drug-Resistant TB, which is much harder to treat.

• Nutrition and Living Conditions: Crowded housing and malnutrition weaken the immune system.

Example: In high-density urban informal settlements, one undiagnosed case can spread rapidly due to lack of ventilation.

• Urbanization and Migration: Tracking floating populations like construction workers is difficult.

Example: Migrant workers often change locations mid-treatment, leading to lost-to-follow-up cases.

Way Ahead:

• Universal Access to Molecular Testing: Replacing traditional sputum microscopy with faster, more accurate molecular tests (like TruNat/CBNAAT) nationwide.
• Localized Strategy: Utilizing data-driven tools to identify high-risk hotspots at the village and ward levels for targeted intervention.
• Vaccine Research: Accelerating the Made-in-India TB vaccine candidates currently in clinical trials to provide long-term immunity.
• Private Sector Engagement: Integrating private practitioners into the Ni-kshay portal to ensure standardized treatment for all patients.
• Sustaining Jan Bhagidari: Expanding the Ni-kshay Mitra pool to include corporate CSR and youth platforms like My Bharat for psychosocial support.
