Why in the News?

Recently, World AIDS Day 2024 renewed attention on India’s HIV progress and rising TB burden. WHO’s Global TB Report 2025 highlighted India holding 25% of global TB and MDR-TB cases, demanding stronger, faster action.

Introduction

India’s public health journey against AIDS and tuberculosis (TB) shows how strong planning, quick action and effective models can save millions of lives. From the 1980s HIV crisis to today’s TB challenge, India has made progress but still faces huge gaps. Learning from proven models like Tamil Nadu’s approach is crucial for ending TB.

Early HIV Crisis: A Look Back

Global AIDS Situation in the 1980s

  • In the mid-1980s, AIDS devastated young adults in southern and eastern Africa.
  • Many African nations had double-digit HIV prevalence rates.
  • With no treatment available then, almost every HIV-positive person eventually developed AIDS.
  • “Opportunistic infections” like tuberculosis (TB) and diarrhoea caused extremely high mortality.
  • The disease wiped out an entire generation in several countries.

India’s HIV Situation in the Early 1990s

  • By the early 1990s, HIV had spread to almost all parts of India.
  • The national adult HIV prevalence remained below 1%, but the spread was wide.
  • Transmission in most states occurred through unprotected heterosexual sex.
  • In certain north-eastern states, HIV spread mainly through needle-sharing among youth using narcotic drugs.
  • India was headed toward a major health crisis unless urgent intervention began.

Turning Point: India’s Early Response to HIV

Launch of the National AIDS Control Project (1992)

  • In 1992, the Government of India launched the National AIDS Control Project.
  • Funding came through an $84 million World Bank soft loan.
  • Every state established its own AIDS Cell under the medical directorate.
  • However, fund movement through central and state systems was extremely slow, delaying implementation.

Birth of the TNSACS Model in 1994

  • Tamil Nadu found a breakthrough solution in 1994.
  • The State AIDS Cell was transformed into a registered society named Tamil Nadu State AIDS Control Society (TNSACS).
  • TNSACS was registered under the Societies Registration Act.
  • This enabled direct fund flow to the society, ensuring faster implementation.
  • Greater autonomy improved planning, awareness, and monitoring.
  • The official website remains www.tnsacs.in.

Awareness as the Only Weapon

  • During the early years, HIV had no cure and no treatment.
  • Raising awareness among all adults was the most powerful and urgent strategy.
  • Campaigns focused on: o Safe sex o Prevention messaging o Reducing stigma o Community engagement
  • Tamil Nadu saw a sharp decline in new HIV infections.
  • Cumulative infections plateaued, even though the state had earlier been a major hotspot.

National Adoption of the TNSACS Model

  • India and the World Bank recognised the effectiveness of the Tamil Nadu approach.
  • During the Second National AIDS Control Project (1997–2002), the TNSACS model became a national mandate.
  • Every state converted its AIDS Cell into a similar AIDS Control Society.
  • Nationwide awareness campaigns soon followed.
  • Result: India’s adult HIV prevalence fell from 0.54% in 2000 to 0.22% today, marking a major public health success.

India’s Current Challenge: TB and MDR-TB Crisis

WHO Global TB Report 2025 Findings

The 2025 WHO Global TB Report highlights a severe situation:

o India has 25% of the world’s TB infections (36 million globally). o India accounts for 7.5% of global people living with HIV (40 million). o TB remains the most common opportunistic infection in people with HIV. o TB causes 25% of AIDS-related deaths in India. o India also has 25% of global MDR-TB cases, adding another serious challenge.

India’s Ambitious Target for TB Elimination

  • Globally, TB elimination is targeted for 2030.
  • India set an ambitious target to eliminate TB by 2025, five years earlier.
  • As 2025 ends, the goal has not been reached.
  • However, India’s decline in TB cases is faster than the global average, showing progress.
  • Ministry of Health and Family Welfare has prioritised: o TB testing o Reporting o Treatment access o MDR-TB monitoring o Early detection
  • HIV-TB co-infection remains a high-risk area needing constant attention.

Pradhan Mantri TB Mukt Bharat Abhiyaan (PMTBMBA)

  • PMTBMBA provides crucial support for TB patients.
  • It focuses on: o Nutrition support o Community participation o Corporate Social Responsibility partnerships o Faster diagnosis o Continuous treatment
  • The programme aims to bring down both TB incidence and mortality through a whole-of-society approach.

State Variations in TB Burden

Uneven Distribution of TB across States

  • As with other socio-economic indicators, TB cases vary widely across India.
  • Five states, Uttar Pradesh, Maharashtra, Madhya Pradesh, Bihar, and Rajasthan account for 56% of all TB cases reported in 2024.
  • The concentration of TB burden requires state-specific strategies and resource allocation.

Tamil Nadu Again Leads the Way: A New Model for TB Reduction

Tamil Nadu’s Technological Breakthrough

  • Tamil Nadu became the first Indian state to integrate a TB-death prediction model into its existing screening system.
  • This model predicts which TB patients may be at higher risk of death.
  • The innovation was developed by ICMR–National Institute of Epidemiology (ICMR-NIE).
  • The model helps reduce TB mortality by enabling: o Timely intervention o Targeted care o Improved follow-up o Early detection of high-risk cases

How Tamil Nadu Implements This System

  • Screening uses rapid test kits as the first step.
  • After diagnosis, the process involves: o Case reporting o Starting treatment early o Providing nutrition support o Using the ICMR-NIE software to monitor risks
  • This model strengthens the entire care pathway from detection to recovery.

Strong Partnership between State and Centre

o Tamil Nadu’s National Health Mission team works closely with the Central government’s State TB Office. o Both teams function with the same goal: reducing TB burden. o Efficient delivery, fast technology adoption, and strong coordination make the Tamil Nadu model highly effective.

Parallels between Tamil Nadu’s HIV and TB Success

  • Tamil Nadu controlled the AIDS crisis early through TNSACS.
  • The state is now using a similar innovative, autonomous and technology-supported model for TB.
  • This consistency shows: o Good governance matters o Rapid adoption of evidence-based solutions saves lives o Decentralised and empowered systems deliver results

Lessons for India: The Way Forward

What the Nation Can Learn

  • Accelerate technology use across all states
  • Strengthen rapid testing systems
  • Improve fund flow by empowering state-level bodies
  • Expand nutrition and community support
  • Monitor MDR-TB aggressively
  • Integrate predictive models into national TB programmes.
  • Learn from the TNSACS experience of fast, decentralised action

Conclusions

India’s experience with HIV and TB shows that strong planning, quick adoption of effective models, and technology-driven systems can save lives. Learning from Tamil Nadu’s successes is essential for reducing infections and achieving national elimination goals. To further improve TB control efforts, India should focus on:

  1. Expanding access to antiretroviral therapy for HIV-TB co-infected patients
  2. Addressing latent TB infection through improved screening and preventive measures
  3. Reducing the TB mortality rate through early detection and treatment
  4. Strengthening primary healthcare centers to better handle TB cases
  5. Improving overall healthcare infrastructure to support TB elimination efforts
  6. Implementing widespread TB preventive treatment programs
  7. Enhancing detection of sputum smear positive cases for faster diagnosis
  8. Utilizing video observed therapy to improve treatment adherence
  9. Deploying mobile diagnostic units to reach remote areas
  10. Adopting digital adherence technologies to monitor treatment progress
  11. Ensuring consistent TB drug supply across all healthcare facilities
  12. Expanding the Ni-kshay Poshan Yojana to provide nutritional support to more TB patients
  13. Addressing treatment interruptions through improved patient support systems
  14. Developing comprehensive TB elimination strategies tailored to regional needs

By implementing these measures and learning from successful models like Tamil Nadu’s, India can make significant progress towards its goal of TB elimination.
