India has made remarkable progress in reducing tuberculosis (TB) cases and deaths. Between 2015 and 2024, new TB cases fell by 21% and deaths by 28%, according to the World Health Organisation’s 2025 report. This success is due to India’s focused health strategies, advanced technology, and community involvement. The country is on track to eliminate TB by 2025, ahead of the global target year.
About Tuberculosis and Its Impact
Tuberculosis is caused by the bacterium “Mycobacterium tuberculosis”. It mainly affects the lungs but can target other organs like the brain and spine. TB spreads through airborne droplets when an infected person coughs or sneezes. People with latent TB carry the bacteria without symptoms and cannot spread the disease but may develop active TB later. Children and those with weak immunity are more vulnerable. Untreated active TB can be fatal.
India’s Strategic Approach to End TB
India’s National Strategic Plan to End TB 2020-25 focuses on four pillars – Build, Prevent, Detect, and Treat. The National Tuberculosis Elimination Programme (NTEP) replaced the earlier Revised National Tuberculosis Control Program in 2020. It emphasises early diagnosis, prompt treatment, patient support, and prevention measures. The Pradhan Mantri TB Mukt Bharat Abhiyaan launched in 2022 mobilises public participation and corporate social responsibility to accelerate TB elimination.
Key Programmes and Innovations
The Nikshay Poshan Yojana provides nutritional support to TB patients. Ni-kshay Mitras are volunteers who assist patients with food and psychosocial help. The 100-Day TB Mukt Bharat Abhiyan launched in 2024 intensified screening and treatment in high-priority districts. New drug regimens like BPaLM shorten treatment for drug-resistant TB. AI tools such as cough analysis apps and AI-based chest X-rays improve detection and management. Over 9800 rapid testing centres and 107 drug susceptibility labs support early diagnosis.
Reaching Remote Areas and Technological Advances
Mobile testing vans and portable X-rays have brought TB screening to remote regions like Kashmir’s Gurez valley. AI-driven predictive analytics identify patients at risk of treatment failure, improving outcomes. Digital platforms enable direct benefit transfers for patient nutrition. The integration of technology with community health centres under the Ayushman Bharat scheme expands affordable healthcare access.

Answer Hints:
1. Critically discuss the role of technology and AI in enhancing public health initiatives like tuberculosis control in India. [GS-III-Science & Technology]
- AI tools like Cough Against TB app analyze cough sounds for rapid, non-invasive TB screening, increasing case detection by 12-16% over conventional methods.
- DeepCXR AI automates chest X-ray reading, addressing specialist shortages and enabling early diagnosis in resource-limited settings.
- Predictive analytics identify patients at high risk of treatment failure, allowing timely interventions and reducing adverse outcomes by 27%.
- Over 9800 rapid molecular testing labs form the world’s largest network, enabling quick and accurate TB diagnosis nationwide.
- Digital platforms like Ni-kshay facilitate direct benefit transfers, patient tracking, and data management, improving treatment adherence and program efficiency.
- Technology integration accelerates screening, diagnosis, and treatment, supporting India’s goal of TB elimination ahead of global targets.
2. Examine the importance of community participation and multi-sectoral approaches in disease elimination programmes with reference to the National Tuberculosis Elimination Programme. [GS-II-Governance]
- Community volunteers (Ni-kshay Mitras) provide nutritional, psychosocial, and vocational support, reducing patient dropouts and improving outcomes.
- Pradhan Mantri TB Mukt Bharat Abhiyaan mobilizes public ‘Jan Andolan’, involving over 30,000 elected representatives and multiple ministries, ensuring whole-of-society participation.
- Engagement of private healthcare providers expands reach and ensures comprehensive case detection and treatment.
- Multi-sectoral response addresses social determinants like nutrition, housing, and stigma, critical for sustained disease elimination.
- Collaboration with NGOs, civil society, corporate CSR initiatives leverages resources and awareness for better program impact.
- Community involvement creates ownership, reduces stigma, and promotes early health-seeking behavior essential for TB control.
3. Estimate the challenges in delivering healthcare services in remote and mountainous regions of India, and analyse how mobile health units and digital platforms can mitigate these challenges. [GS-III-Health & Environment]
- Geographical barriers such as difficult terrain, harsh weather, and poor connectivity limit access to healthcare facilities in remote areas like Kashmir’s Gurez valley.
- Scarcity of healthcare professionals and diagnostic infrastructure hampers early disease detection and treatment.
- Mobile testing vans equipped with portable X-ray and diagnostic tools bring services directly to isolated populations, overcoming access issues.
- Digital platforms enable real-time data reporting, patient tracking, and direct benefit transfers, ensuring continuous care despite physical barriers.
- AI-enabled tools facilitate remote screening and diagnosis, reducing dependence on specialist availability.
- Community engagement and awareness sessions with local leaders enhance acceptance and utilization of healthcare services in remote regions.
4. Point out the significance of nutritional support and psychosocial care in managing long-term infectious diseases and discuss their impact on treatment adherence and success rates. [GS-IV-Ethics, Integrity and Aptitude]
- Long TB treatment (6+ months) causes side effects and nutritional depletion; high-protein diets aid recovery and drug tolerance.
- Nikshay Poshan Yojana provides direct financial support (Rs. 1000/month) to TB patients for nutrition, reducing out-of-pocket expenses.
- Ni-kshay Mitras offer psychosocial support, helping patients cope with stigma, mental stress, and treatment fatigue.
- Psychosocial care improves patient motivation, adherence to lengthy treatment regimens, reducing default rates and drug resistance.
- Combined nutritional and emotional support contribute to higher treatment success rates (90% under TB Mukt Bharat Abhiyan) surpassing global averages.
- Ethical patient-centric care respects dignity and encourages trust, essential for effective public health interventions.
