Understanding Tuberculosis: A Comprehensive Guide to Prevention, Diagnosis, & Cure
Tuberculosis (TB) continues to be one of the most significant public health challenges in India and across the world. Despite advances in medical science, TB still affects millions every year—often silently, often misunderstood. According to the World Health Organisation (WHO), India carries the highest burden of tuberculosis globally, with a large percentage of the population harbouring latent TB infection.
At Wellness Hospitals in Hyderabad, we strongly believe that awareness leads to early diagnosis, and early diagnosis saves lives. Tuberculosis is no longer a disease of the past—it remains a very present concern today. The good news is that TB is completely preventable, treatable, and curable with the right medical care and timely intervention.
This comprehensive guide, provided by our Pulmonology Department, explains everything you need to know about tuberculosis—from causes and symptoms to diagnosis, treatment, prevention, and recovery.
What Is Tuberculosis (TB)?

Tuberculosis is a bacterial infectious disease caused by Mycobacterium tuberculosis. It most commonly affects the lungs (called Pulmonary TB), but it can also involve other organs, such as:
- Lymph nodes
- Kidneys
- Spine
- Brain
- Abdomen
This form is known as Extrapulmonary Tuberculosis.
Decades ago, TB was often fatal. Today, thanks to modern antibiotics, structured treatment programs, and improved diagnostics, TB can be cured successfully when detected early and treated completely.
How Does Tuberculosis Spread?
One of the most common myths about TB is that it spreads through touch or sharing food. This is not true.
TB is an airborne disease.
It spreads when a person with active pulmonary TB:
- Coughs
- Sneezes
- Talks
- Laughs
- Sings
Tiny droplets containing TB bacteria remain suspended in the air and can be inhaled by others—especially in crowded or poorly ventilated spaces.
You are at higher risk if you:
- Live with or spend prolonged time with someone who has active TB
- Work in crowded environments (factories, hostels, prisons, healthcare facilities)
- Have a weakened immune system due to diabetes, HIV, cancer, or malnutrition
👉 Important: Not everyone exposed to TB bacteria becomes sick. This leads us to the two major forms of TB.
Types of Tuberculosis: Latent vs Active
- Latent TB Infection (LTBI)
- TB bacteria are present but inactive
- No symptoms
- Not contagious
- Detected via skin test or blood test
- Can turn into active TB if immunity weakens
- Active TB Disease
- Bacteria multiply and cause illness
- Symptoms are present
- Highly contagious
- Requires immediate treatment
Other Classifications of TB
- Pulmonary TB: Affects lungs (most common)
- Extrapulmonary TB: Affects organs outside the lungs
- Miliary TB: Rare, severe form spreading through the bloodstream
- Drug-Resistant TB (MDR-TB): Resistant to standard TB drugs
Signs & Symptoms of Tuberculosis
If you have a cough that lasts more than 3 weeks, do not ignore it.
Common TB Symptoms Include:
- Persistent cough
- Chest pain while breathing or coughing
- Coughing up blood or sputum
- Unexplained weight loss
- Persistent fever and chills
- Night sweats
- Severe fatigue and weakness
Early diagnosis prevents complications and protects your family.
How Tuberculosis Is Diagnosed at Wellness Hospitals
Accurate diagnosis is the foundation of successful TB treatment. At Wellness Hospitals in Hyderabad, we use advanced, WHO-approved diagnostic methods:
- Mantoux Tuberculin Skin Test
- IGRA Blood Test (QuantiFERON-TB Gold)
- Digital Chest X-ray
- Sputum Smear & Culture (Gold Standard)
- CBNAAT / GeneXpert Test – detects TB and drug resistance within hours
- Bronchoscopy & Biopsy for complex cases
Our pulmonologists ensure early detection and precise treatment planning.
- Treatment of Tuberculosis: The Road to Recovery
- TB treatment is highly effective but requires discipline.
- DOTS Strategy (Directly Observed Therapy Short Course)
TB is treated with a combination of antibiotics for a minimum of 6 months, following WHO-recommended DOTS guidelines.
Why Completing TB Treatment Is Critical
- Prevents drug resistance
- Ensures complete cure
- Stops spread to others
- Reduces relapse risk
Stopping medication early can cause Multi-Drug Resistant TB (MDR-TB), which is much harder to treat.
At Wellness Hospitals, we provide treatment monitoring, counselling, and nutritional support to ensure full recovery.
