Tuberculosis (TB) is a contagious, airborne infectious disease primarily caused by the bacterium Mycobacterium tuberculosis. Although it mainly affects the lungs, it can also impact other organs such as the kidneys, spine, and brain. TB is one of the world’s oldest known diseases and continues to be a major public health challenge, particularly in developing countries.
Transmission
TB is spread through the air when an infected person with active TB in their lungs coughs, sneezes, or speaks, releasing tiny droplets containing the bacteria. Close, prolonged contact is usually necessary for transmission, which is why it often spreads in crowded environments. Not everyone exposed to TB will become infected; the risk of developing TB depends on the strength of a person’s immune system and other factors.
Symptoms
Chest pain
Fatigue
Fever and night sweats
Weight loss and loss of appetite
Diagnosis
Tuberculin Skin Test (TST)
Interferon-Gamma Release Assays (IGRA)
Chest X-rays and CT Scans
Sputum Test
Treatment
TB is curable with a regimen of antibiotics taken over six to nine months. The standard treatment is the DOTS (Directly Observed Treatment, Short-Course) approach, which includes:
First-line Drugs
Isoniazid, rifampicin, ethambutol, and pyrazinamide. These are taken for the initial two months (intensive phase), followed by four months of isoniazid and rifampicin.
Drug-Resistant TB
This includes multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB), requiring second-line medications and longer treatment durations, which are often less effective and more toxic.
