Overview and Definition
Tuberculosis (TB) is a serious, highly infectious bacterial disease caused by a microscopic pathogen known as Mycobacterium tuberculosis. Unlike viral infections, this bacterium has a unique, waxy cell wall that allows it to survive inside the body’s immune cells for long periods. While TB can biologically target almost any part of the body—including the kidneys, spine, and brain—it most commonly invades the respiratory system, establishing a localized infection within the lung tissue.
At Liv Hospital, we categorize TB into two primary biological states:
Symptoms and Risk Factors
The symptoms of active pulmonary Tuberculosis develop gradually as the bacterial colony expands and compromises the respiratory architecture. Key clinical indicators include:
While anyone can inhale the airborne bacteria, specific biological conditions increase the risk of the infection transitioning from latent to active. A compromised immune system—due to conditions like HIV, diabetes, severe kidney disease, or immunosuppressive therapies—leaves the lung tissue vulnerable to rapid bacterial multiplication.
Environmental factors, such as living in poorly ventilated, crowded spaces, also accelerate the mechanical transmission of the pathogen. At Liv Hospital, we analyze these risk factors to identify high-risk individuals early.
Diagnosis and Evaluation
A definitive diagnosis of Tuberculosis requires identifying the bacteria at the cellular level. At Liv Hospital, we look beyond the traditional skin test (Mantoux) by utilizing highly sensitive blood tests known as Interferon-Gamma Release Assays (IGRAs). For symptomatic patients, we analyze sputum samples using specialized acid-fast bacilli (AFB) smearing and rapid liquid cultures to confirm the presence of live mycobacteria.
To assess the structural damage inside the thoracic cavity, our specialists use high-resolution chest X-rays and computed tomography (CT) scans, looking for characteristic “cavities” or shadows left by the infection in the upper lobes of the lungs. We also utilize advanced molecular diagnostic tools, such as the GeneXpert® assay. This technology uses DNA amplification to identify the Mycobacterium tuberculosis genome within hours, allowing us to simultaneously check for genetic resistance to primary medications.
Treatment and Management
Treating Tuberculosis requires a specialized, multi-drug biological approach to ensure all bacterial cells are eradicated. Unlike standard bacterial infections that resolve in a few days, a standard TB treatment course lasts between 6 to 9 months. Patients are prescribed a combination of four primary biological agents: isoniazid, rifampin, ethambutol, and pyrazinamide. This intensive regimen is designed to target the bacteria at various stages of their metabolic cycle.
When genetic mapping reveals Multi-Drug Resistant TB (MDR-TB), the bacteria have evolved to survive standard medications. At Liv Hospital, our pulmonologists and infectious disease specialists step in with customized, secondary lines of defense. This involves an advanced combination of specialized injectable or oral medications taken for up to 20 months. Throughout this period, we provide close medical supervision to monitor liver and kidney functions, ensuring the body processes the intense therapies safely.
Recovery and Prevention
The most critical factor in recovering from Tuberculosis is strict adherence to the medication schedule. Stopping the antibiotics early—even if symptoms disappear—allows the strongest remaining bacteria to mutate, leading to a dangerous biological relapse of drug-resistant disease. As the lungs heal from the structural inflammation, our team monitors your progress with follow-up imaging and sputum tests to confirm the complete biological clearance of the pathogen.

Tuberculosis is a chronic, granulomatous infectious disease caused by the bacterium Mycobacterium tuberculosis, primarily affecting the lungs but capable of invading any organ of the body.
Medically, latent tuberculosis infection is a state of infection, not a disease; you harbor the bacteria, but there is no active illness, no symptoms, and no risk of contagion unless it reactivates.
Untreated active tuberculosis disease destroys lung tissue, leading to respiratory failure; it can also cause fatal bleeding (hemorrhage) or spread to vital organs like the brain, causing meningitis.
“Infection” means the bacteria are in your body (often dormant/latent), while “disease” means the bacteria are actively multiplying, damaging tissue, and making you sick.
It was called the White Plague because of the extreme paleness (pallor) seen in patients with advanced disease, in contrast to the “Black Death” (plague), which caused dark skin discolorations.
