Tuberculosis remains one of the most persistent infectious diseases in India. The good news is that TB is completely curable when diagnosed early and treated properly.
This blog explains the symptoms, diagnosis, treatment, and prevention of TB.

What is Tuberculosis (TB)?

Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis.
It mainly affects the lungs but can spread to the spine, lymph nodes, kidneys, intestines, bones, and even the brain.

TB spreads through airborne particles when an infected person coughs, sneezes, or talks.
It does not spread through physical touch, handshakes, food sharing, or utensils.

Types of Tuberculosis

1. Latent TB Infection (LTBI)

• Bacteria remain inactive inside the body
• No symptoms
• Not contagious
• Can become active later if immunity weakens

2. Active TB Disease

• Bacteria multiply and cause symptoms
• Highly contagious
• Needs immediate medical treatment

Symptoms of Tuberculosis

TB symptoms vary depending on whether it affects the lungs or other organs.

Pulmonary TB Symptoms (Lungs)

• Cough lasting for 2–3 weeks or more
  Persistent cough is the most common early sign.
• Coughing up blood (Hemoptysis)
  Suggests advanced infection.
• Chest pain and difficulty breathing
  Discomfort increases with deep breathing or coughing.
• Fever and night sweats
  Usually mild fever, more noticeable in the evenings.
• Rapid weight loss and loss of appetite
  TB commonly causes unintended weight loss.
• Extreme fatigue
  Due to reduced oxygen exchange.

Extrapulmonary TB Symptoms

When TB affects organs other than the lungs:

• Lymph Node TB: Swelling in the neck or armpit
• Spinal TB: Backache, stiffness
• Kidney TB: Blood in urine
• Bone TB: Painful joint swelling
• Brain TB (TB Meningitis): Headache, vomiting, confusion
• Intestinal TB: Abdominal pain, diarrhea

Early detection prevents severe and life-threatening complications.

How TB Is Diagnosed

Accurate and timely diagnosis is crucial. Early screening in Pune and PCMC helps prevent community spread.

1. Clinical Examination

The doctor checks:

• Symptoms
• Breathing pattern
• Medical history
• Possible exposure

2. Chest X-ray

Used to identify lung lesions, cavities, nodules, or fluid accumulation.

3. Sputum Tests (Most Crucial)

• AFB Smear Microscopy
  Detects TB bacteria under a microscope.
• CBNAAT / GeneXpert Test
  Detects TB DNA
  Identifies rifampicin resistance
  Widely used in Pune and PCMC for rapid confirmation.

4. Mantoux Test (Skin Test)

A small amount of tuberculin is injected under the skin.
Swelling indicates TB exposure.

5. Blood Tests

• IGRA (Interferon-Gamma Release Assay)
• CBC and ESR

Helpful for detecting latent TB.

6. CT Scan Chest

Provides detailed images of lung damage.

7. Biopsy

Used for extrapulmonary TB in organs like lymph nodes, spine, or brain.

Treatment Options for Tuberculosis

TB is fully curable if the patient follows the complete treatment course. Typical treatment lasts 6 to 9 months.

1. First-Line TB Treatment: DOTS Therapy

DOTS (Directly Observed Treatment, Short-Course) is the global standard.

Medicines used:

• Isoniazid (INH)
• Rifampicin (RIF)
• Ethambutol (EMB)
• Pyrazinamide (PZA)

Treatment Phases:

• Intensive Phase: 2 months
• Continuation Phase: 4–7 months

Finishing the full course is essential.

2. MDR-TB Treatment (Multidrug-Resistant TB)

This occurs when TB bacteria resist INH and Rifampicin.

Treatment lasts 18–24 months using:

• Fluoroquinolones
• Second-line injectables
• Newer drugs like Bedaquiline or Delamanid

3. XDR-TB (Extensively Drug-Resistant TB)

A severe type requiring advanced therapy and expert monitoring.

4. Treatment for Latent TB

To prevent progression to active TB:

• Isoniazid for 6–9 months
• Rifampicin for 4 months
• INH and Rifapentine weekly

5. Supportive Care

• High-protein diet
• Adequate hydration
• Regular follow-up
• Managing side effects

Prevention of Tuberculosis

• BCG vaccination for children
