Understanding Tuberculosis Symptoms, Types, Causes and Diagnosis

Tuberculosis, which is commonly referred to as TB, is a type of bacterial infection caused by Mycobacterium tuberculosis. It is highly contagious and spreads through the air, infecting millions annually. TB is among the leading causes of untimely death globally. The disease is transmitted through droplets released when an infected person coughs or sneezes.

The lungs are the most commonly affected organ in TB, causing pulmonary tuberculosis. However, TB can also affect other body parts such as the endocrine glands, bones, nervous system, and abdomen. It is most prevalent in low- and middle-income countries with poor socioeconomic conditions. Fortunately, timely diagnosis and prompt treatment with anti-tubercular medications can effectively treat TB. In addition, immunization with the BCG vaccine during childhood provides lifelong immunity against TB and remains the most effective prevention method.

What are the signs and symptoms of tuberculosis?

The symptoms of tuberculosis typically appear slowly and progress gradually. Once infected with the tubercle bacteria, the following symptoms may develop: 

· A cough that persists for more than three months and produces phlegm

· Unintentional weight loss

· Night sweats

· Chest pain

· Fever

· Coughing up blood

· Loss of appetite

· Fatigue

How is tuberculosis diagnosed?

To diagnose tuberculosis, a medical professional typically starts with a patient's medical history, a physical exam, and a chest X-ray. Laboratory tests, including the Mantoux tuberculin test or tuberculin skin test (TST), and a sputum smear test, is commonly used to confirm an active tuberculosis infection. The TST is a blood test that measures the immune system's response to the Mycobacterium tuberculosis bacteria. This test involves injecting a substance called tuberculin into the lower arm and observing the reaction. Additionally, the sputum smear test involves testing a sample of the patient's sputum for acid-fast bacilli (AFB) using microbiological techniques. If the AFB test is positive, a 24-hour culture is performed to detect the growth of the tubercle bacteria. An anti-tubercular drug resistance test may also be conducted to determine the most appropriate medication for the particular infection, especially in cases of MDR TB.
