Types Of Tuberculosis

Tuberculosis can affect the lungs as well as other parts of the body. Based on how the infection behaves and where it spreads, TB is classified into several types:

• Latent TB Infection (LTBI): The TB bacteria remain inactive in the body and do not cause symptoms. People with latent TB are not contagious, but the infection can become active if the immune system becomes weak.
• Active TB Disease: The bacteria become active and multiply in the body, causing symptoms such as persistent cough, fever, night sweats, and weight loss. This form can spread to others if it affects the lungs.
• Pulmonary TB: The most common form of tuberculosis that affects the lungs and spreads through airborne droplets when an infected person coughs, sneezes, or speaks.
• Extrapulmonary TB: Occurs when TB bacteria spread beyond the lungs to other organs such as the lymph nodes, bones, brain, kidneys, or abdomen.
• Military TB: A rare but severe form in which TB bacteria spread through the bloodstream and affect multiple organs throughout the body.
• Drug-Resistant TB: Includes multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB), where the bacteria become resistant to standard TB medications, making treatment more complex and prolonged.

Recognising these types helps healthcare professionals diagnose TB accurately and provide the most appropriate treatment.

Global TB Statistics 2026 (Latest WHO Data)

Tuberculosis remains a major global health concern and one of the leading causes of death from infectious diseases worldwide, highlighting the urgent need for stronger prevention, early diagnosis, and effective treatment.

• Incidence Rate: Reduced from 237 per lakh population in 2015 to 187 per lakh in 2024
• Mortality Rate: Declined from 28 per lakh in 2015 to 21 per lakh in 2024
• Diagnosed Cases: About 26.18 lakh TB cases detected in 2024
• Treatment Coverage: Increased from 53% in 2015 to 92% in 2024
• Latent TB Infection: Nearly 40% of the population may carry latent TB infection
• Drug-Resistant TB: Approximately 2.5% of new TB cases and 13% of previously treated cases are drug-resistant

These figures highlight both the scale of TB in India and the progress being made through national programmes, improved diagnosis, and expanded treatment access.

How TB Spreads

Option 1: Tuberculosis spreads through the air when a person with active TB disease in the lungs or throat releases bacteria into the surrounding environment. Understanding how TB spreads can help you take preventive measures and reduce the risk of infection.

Common ways TB spreads:

• Coughing or sneezing: An infected person releases bacteria-containing droplets into the air.
• Talking or singing closely: Tiny infectious droplets can be inhaled by people nearby.
• Prolonged close contact: Spending extended time with someone who has untreated active TB increases the risk of infection.
• Crowded or poorly ventilated environments: Limited airflow allows TB bacteria to remain suspended in the air for longer periods.

Important facts about TB transmission:

• Only individuals with active TB disease can spread the infection.
• People with latent TB infection do not have symptoms and cannot transmit TB to others.
• TB does not spread through casual contact, such as shaking hands, sharing food or drinks, or touching surfaces like bed linens or toilet seats.
• With proper treatment, people with active TB usually become significantly less contagious within 2 to 3 weeks.

Recognising how tuberculosis spreads is essential for prevention, early diagnosis, and protecting both individuals and communities from infection.

Symptoms Of Tuberculosis

Tuberculosis symptoms usually develop gradually and may vary depending on the part of the body affected. Early recognition of symptoms helps ensure timely diagnosis and treatment.

Common symptoms of TB include:

• Persistent cough lasting more than two to three weeks
• Coughing up blood or sputum
• Chest pain or difficulty breathing
• Fever and night sweats
• Unexplained weight loss
• Fatigue and weakness
• Loss of appetite

Symptoms when TB affects other organs:

• Swollen lymph nodes, especially in the neck
• Back pain if the spine is affected
• Headache or confusion in severe cases

If you experience these symptoms, especially a persistent cough, consult a healthcare professional for evaluation and testing.

Who Is At Higher Risk Of TB?

Certain individuals have a higher risk of developing tuberculosis:

• People with weakened immune systems
• Individuals living with HIV
• People with diabetes or chronic illnesses
• Those living in crowded or poorly ventilated conditions
• Healthcare workers exposed to TB patients
• Smokers or individuals with lung disease
• Children and elderly individuals

TB Diagnosis: Tests And Screening

Diagnosing TB requires clinical evaluation and laboratory testing. Common tests include:

1. Sputum Test to detect TB bacteria in mucus from the lungs
2. Chest X-Ray to identify lung abnormalities
3. Tuberculin Skin Test (TST) to detect immune response to TB bacteria
4. Molecular Tests to identify TB bacteria and drug resistance quickly

Accurate diagnostic testing plays a key role in early detection and effective treatment.

Importance Of Early Detection

Early detection of tuberculosis significantly improves treatment outcomes. When TB is diagnosed early, treatment can begin before the disease causes serious complications or spreads to others.

Timely diagnosis also reduces the risk of drug-resistant TB, which is more difficult to treat. Screening individuals with symptoms or those at higher risk helps control the spread of the infection in communities.

TB Treatment And DOTS Strategy

Tuberculosis is treatable with a combination of antibiotics known as Anti Tubercular Therapy (ATT). Treatment typically lasts six to nine months.

The Directly Observed Treatment Short-course (DOTS) strategy ensures that patients take their medications regularly under supervision. This approach improves treatment success rates and helps prevent drug resistance.

Completing the full course of medication is essential for curing the disease.

Drug-Resistant TB: A Growing Concern

Drug-resistant TB occurs when TB bacteria become resistant to commonly used medications. This can happen if treatment is incomplete or incorrect.

Multidrug-resistant TB requires longer treatment with specialised medications and careful monitoring. Strengthening diagnostic systems and ensuring treatment adherence are critical to controlling drug-resistant TB.

TB Prevention Tips

You can reduce your risk of tuberculosis by following preventive measures:

• Ensure good ventilation in homes and workplaces
• Cover your mouth and nose while coughing or sneezing
• Maintain a healthy immune system through balanced nutrition
• Avoid smoking and substance abuse
• Seek medical advice if you experience persistent respiratory symptoms
• Ensure children receive recommended vaccinations such as BCG
