What is a TB Infection?
Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but can attack any part of the body such as the kidney, spine, and brain.
TB is easily transmitted from person to person through the air. When a person develops active TB disease the symptoms (cough, fever, night sweats, weight loss etc.) may be mild for many months leading to delays in seeking care. Such delays may result in increased transmission of the infection to others (10-15 people over the course of a year), and an increase in the severity of TB infection. In such instances, TB infection can spreads outside of the lungs to other parts of the body. TB infection is also harmful to patients in a state of immunosuppression such as HIV, or those who are drug resistant. In such instances, mortality rates are high. Thus, diagnostic tests to aid in early detection of TB infection are very important.
Detection of TB is done by a TB skin test (TST) and/or TB blood test, following by confirmation with chest X-Ray and/or testing of a sputum sample.
