The next six months were filled with challenges. Strict medication schedules, side effects, and social stigma made the journey difficult. However, with proper treatment and the support of her family, Anita gradually recovered. Today, she spreads awareness about TB, encouraging people to seek early medical attention and complete their treatment.
Her story is a reminder that TB is treatable, but timely intervention is key.
What is Tuberculosis (TB)?
Tuberculosis (TB) is a serious infectious disease caused by the bacterium Mycobacterium tuberculosis. It primarily affects the lungs but can also spread to other parts of the body, such as the brain, kidneys, spine, and joints. If left untreated, TB can be life-threatening. Despite being a preventable and treatable disease, TB remains a significant global health concern, particularly in developing countries where access to healthcare may be limited.
How Does TB Spread?
TB is an airborne disease transmitted through tiny respiratory droplets released when an infected person coughs, sneezes, laughs, or talks. These droplets can linger in the air for hours, increasing the risk of inhalation by others. However, TB does not spread through physical contact, shared food, or drinks. People living in close quarters with an infected individual, such as family members or colleagues, are at a higher risk of contracting the disease.
Symptoms of Tuberculosis
The symptoms of TB can vary depending on the affected body part. The most common signs include:
- A persistent cough lasting more than three weeks
- Coughing up blood or sputum (mucus from the lungs)
- Chest pain or difficulty breathing
- Chronic fatigue and weakness
- Unintentional weight loss and loss of appetite
- Night sweats and frequent fever
- Chills and prolonged low-grade fever
If TB spreads beyond the lungs, it can cause additional symptoms, such as swollen lymph nodes, severe back pain, joint pain, and neurological issues in cases of TB meningitis.
Types of Tuberculosis
- Latent TB: The bacteria remain in the body but do not cause symptoms. The immune system keeps them under control, but they can become active later if immunity weakens. People with latent TB are not contagious but still require preventive treatment to avoid reactivation.
- Active TB: The bacteria multiply, leading to visible symptoms and making the person contagious. Immediate medical attention and long-term treatment are necessary to prevent complications and the spread of infection.
- Drug-Resistant TB: Some TB strains develop resistance to common antibiotics, making them more difficult to treat. Multi-drug resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) require specialized medications and longer treatment durations.
Diagnosis of Tuberculosis
Early detection of TB is crucial to prevent its spread and complications. Healthcare professionals use the following diagnostic methods:
- Tuberculin Skin Test (TST): A small injection is placed under the skin to check for a reaction, indicating TB exposure.
- Blood Test (Interferon-Gamma Release Assays - IGRA): Detects TB infection by measuring the immune system's response.
- Chest X-ray: Helps identify lung damage associated with TB infection.
- Sputum Microscopy & Culture Test: A laboratory test that examines mucus samples from the lungs for TB bacteria.
- Molecular Testing (PCR): Advanced testing to detect TB bacteria quickly and determine drug resistance.
Treatment for Tuberculosis
TB is treated with a combination of antibiotics for at least 6 to 9 months. The most commonly prescribed medications include:
- Isoniazid (INH)
- Rifampin (RIF)
- Ethambutol (EMB)
- Pyrazinamide (PZA)
It is essential to complete the full course of treatment, even if symptoms improve, to prevent drug resistance. Patients with drug-resistant TB may require alternative medications and a longer treatment duration.
TB Prevention Strategies
Preventing TB involves a combination of personal hygiene, medical interventions, and public health measures:
- Vaccination: The Bacillus Calmette-GuΓ©rin (BCG) vaccine helps protect children from severe TB forms, though its effectiveness in adults varies.
- Good Hygiene Practices: Covering the mouth while coughing or sneezing helps reduce the spread of bacteria.
- Proper Ventilation: Ensuring adequate airflow in living and working spaces minimizes the risk of TB transmission.
- Early Screening & Treatment: People exposed to TB should undergo testing and, if necessary, start preventive medication.
- Nutritional Support: A strong immune system can help prevent latent TB from becoming active.
Global and India’s Efforts in TB Control
Organizations like the World Health Organization (WHO) and India’s National TB Elimination Programme (NTEP) are actively working to eliminate TB through improved healthcare infrastructure, awareness campaigns, and early detection initiatives. The WHO has set a goal to significantly reduce TB cases by 2035. India, which accounts for a large portion of global TB cases, has implemented policies for free treatment and financial support for TB patients to ensure better adherence to therapy.
According to WHO, TB remains one of the top infectious killers globally, despite advancements in medical science. Efforts such as Directly Observed Treatment Short-course (DOTS) and innovative diagnostic tools are being used to enhance TB control programs.

Frequently Asked Questions (FAQs)
1. Can TB be cured completely?
Yes, TB is curable with the right antibiotics and treatment adherence. Completing the full course of medication is crucial to prevent recurrence and drug resistance.
2. Is TB only found in the lungs?
No, while TB primarily affects the lungs (pulmonary TB), it can also spread to other organs like the spine, brain, kidneys, and joints (extrapulmonary TB).
3. Can a vaccinated person still get TB?
Yes, the BCG vaccine provides partial protection, mainly in children, but it does not guarantee immunity against TB infection in adults.
4. Is TB hereditary?
No, TB is an infectious disease that spreads through airborne transmission, not through genetics.
5. How long does TB treatment last?
Treatment usually lasts 6 to 9 months for drug-sensitive TB. Drug-resistant TB may require treatment for up to two years.
Conclusion
Tuberculosis is a preventable and treatable disease, but it requires early diagnosis, proper medical intervention, and patient adherence to treatment. Public awareness and improved healthcare services play a vital role in reducing TB's impact worldwide. If you or someone you know has TB symptoms, consult a healthcare provider immediately.
By taking preventive measures and supporting global TB elimination programs, we can move towards a TB-free world.
