Tuberculosis (TB) is one of the world’s deadliest infectious diseases, but India is fighting back with determination. As the country with the highest burden of TB globally, India is making strides to eliminate the disease by 2025—a goal five years ahead of the global Sustainable Development Goals (SDG) timeline.
This fight against TB isn’t just about healthcare; it’s about engaging communities, fostering awareness, and empowering young people like you to lead the way. Let’s explore the global and national TB scenario, India’s innovative strategies, and how youth can help end TB.
What is Tuberculosis (TB)?
Tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis. It primarily affects the lungs (pulmonary TB) but can also impact other parts of the body such as the kidneys, spine, and brain (extrapulmonary TB). TB spreads through the air when an infected person coughs, sneezes, or speaks, making it a significant public health concern worldwide.
TB is a preventable and treatable disease, yet it remains one of the leading causes of death from infectious diseases. The disease can exist in two forms:
Latent TB: The bacteria remain in the body without causing symptoms, but it can become active later.
Active TB: The bacteria multiply, causing symptoms and making the person contagious.
Symptoms of Tuberculosis
The symptoms of TB vary depending on whether it is pulmonary or extrapulmonary TB, but the most common signs include:
Persistent Cough: A cough lasting more than three weeks, often producing sputum or blood.
Chest Pain: Discomfort or pain in the chest, especially during breathing or coughing.
Fever: Low-grade fever that may worsen over time.
Night Sweats: Excessive sweating at night, often drenching clothes or bedding.
Fatigue: Persistent tiredness or weakness that does not improve with rest.
Unexplained Weight Loss: Significant and unintended loss of body weight.
Loss of Appetite: Reduced desire to eat, leading to malnutrition.
Shortness of Breath: Difficulty breathing, especially in advanced cases.
For extrapulmonary TB, symptoms depend on the affected organ and may include:
Swelling in lymph nodes.
Back pain if the spine is affected.
Blood in the urine in cases involving the kidneys.
Types of Tuberculosis (TB)
Tuberculosis (TB) is a complex disease that can manifest in different forms based on its location in the body and the drug susceptibility of the bacteria. Understanding the types of TB is essential for effective diagnosis, treatment, and prevention. Here’s a breakdown:
1. Pulmonary TB
Description: The most common form of TB, primarily affecting the lungs.
Symptoms: Persistent cough (often with blood), chest pain, shortness of breath, fever, night sweats, and weight loss.
Transmission: Highly contagious and spreads through the air when an infected person coughs, sneezes, or speaks.
2. Extrapulmonary TB
Description: TB that occurs outside the lungs, affecting other organs and systems.
Common Sites:
Lymph Nodes: Swelling, especially in the neck.
Spine (Pott's Disease): Back pain, deformity, or paralysis in severe cases.
Brain (TB Meningitis): Severe headaches, confusion, and neck stiffness.
Kidneys: Blood in urine or abdominal pain.
Bones and Joints: Pain, swelling, and limited movement in the affected area.
Note: Extrapulmonary TB is not usually contagious unless it coexists with pulmonary TB.
3. Latent TB
Description: A dormant form where the bacteria are present in the body but inactive.
Symptoms: None; the person does not feel sick and cannot spread TB.
Significance: Latent TB can activate under certain conditions, such as a weakened immune system, turning into active TB. Preventive treatment is essential for individuals at high risk.
4. Active TB
Description: The bacteria are actively multiplying, causing symptoms and making the individual contagious.
Symptoms: Includes general TB symptoms like persistent cough, fever, and fatigue.
Importance: Immediate treatment is necessary to prevent the disease from spreading and causing complications.
5. Drug-Resistant TB (DR-TB)
Description: A form of TB that does not respond to standard anti-TB drugs.
Types:
Multidrug-Resistant TB (MDR-TB): Resistant to at least isoniazid and rifampicin, two of the most effective TB drugs.
Extensively Drug-Resistant TB (XDR-TB): Resistant to isoniazid, rifampicin, and several second-line drugs, making treatment more complex.
Cause: Often results from incomplete or improper treatment of TB.
6. Miliary TB
Description: A rare but severe form where TB bacteria spread through the bloodstream, affecting multiple organs.
Symptoms: High fever, weakness, difficulty breathing, and systemic symptoms.
Significance: It requires urgent medical attention due to its life-threatening nature.
7. Relapsed or Recurrent TB
Description: TB that returns after treatment due to incomplete eradication of bacteria or re-infection.
Cause: Often linked to weakened immunity or inadequate treatment adherence.
Impact of TB on Society and Communities
TB is more than a health crisis; it is a social and economic burden that disproportionately affects marginalized communities:
Economic Costs: Families of TB patients often face catastrophic healthcare expenses, driving many into poverty. The loss of income due to illness adds to their struggles.
Social Stigma: TB patients frequently experience isolation and discrimination due to misconceptions about the disease, further exacerbating their suffering.
Community Health: The spread of TB is linked to poor living conditions, malnutrition, and lack of awareness, often creating a cycle of vulnerability in low-income communities.
Youth and Education: TB affects young people’s education and career prospects, perpetuating cycles of disadvantage.
By addressing TB, we not only save lives but also uplift communities, reduce poverty, and promote social equity.
The Global TB Scenario
Tuberculosis remains a significant public health challenge worldwide. According to the World Health Organization’s Global TB Report 2023:
Incidence: Around 10.6 million people fell ill with TB in 2022, a 4.5% increase from the previous year, driven partly by the disruptions caused by COVID-19.
Deaths: TB claimed approximately 1.6 million lives in 2022, making it the second deadliest infectious disease globally after COVID-19.
Drug-Resistant TB: An estimated 450,000 cases of multidrug-resistant TB (MDR-TB) were reported, with limited treatment options posing a significant challenge.
Treatment Gap: While global treatment success rates for drug-sensitive TB stood at 86%, for MDR-TB, the success rate was just 60%.
TB in India: A Mixed Picture of Progress and Challenges
India bears the largest share of the global TB burden, accounting for about 26% of global cases. However, the country is also making unprecedented progress:
Incidence: TB incidence in India was 2.55 million cases in 2023, down from 2.74 million in 2022, reflecting a steady decline.
Mortality: India has achieved an 18% reduction in TB-related deaths since 2015, with the mortality rate now at 23 deaths per lakh population.
Treatment Coverage: Over 80% of TB cases in India receive treatment, surpassing the global average.
Drug-Resistant TB: India reported 63,939 cases of MDR-TB in 2023, highlighting the need for continued focus on drug resistance management.

The Four Pillars of Tuberculosis (TB) Elimination: A Comprehensive Framework
The fight against tuberculosis (TB) is guided by a robust framework encapsulated in its four pillars: Detect, Treat, Prevent, and Build. These pillars represent a holistic approach to tackling the disease and achieving its elimination.
Detect focuses on the early identification of TB cases, including drug-resistant strains, by enhancing access to high-sensitivity diagnostic tools and systematically screening high-risk populations. Early diagnosis ensures timely treatment and reduces the risk of transmission.
Treat ensures that all identified patients are initiated and sustained on effective treatment regimens. This is supported by patient-friendly systems and comprehensive social support, including nutritional assistance and financial aid, to improve adherence and outcomes.
Prevent aims to curb the emergence of new TB cases through targeted strategies such as implementing airborne infection control measures, addressing latent TB infections, and mitigating underlying social determinants of health. This includes collaborative efforts across sectors to create healthier environments.
Finally, Build underscores the importance of developing robust policies and institutional frameworks. Strengthening human resource capacities, empowering institutions, and ensuring sufficient financial resources are critical to sustaining progress and scaling efforts toward TB elimination.
Together, these pillars form a dynamic and synergistic approach, fostering a TB-free future and improving the health and well-being of affected communities.
