What is Tuberculosis?
Tuberculosis is a chronic infection of the lungs which is caused by a small aerobic non-motile Mycobacterium tuberculosis. Eventhough this is contagious, unlike any other respiratory infections, tuberculosis is not easy to catch since it divides every 16 to 20 hours, making it an extremely slow compared with other bacteria. It needs repeated and extended exposure to airborne particles to allow sufficient bacterial level in the lungs.
Once the infection becomes an active disease, the patient will experience chest pain, hemoptysis and a persistent productive cough for more than 3 weeks. Other systemic manifestations include fever, chills, shortness of breath, night sweats, loss of appetite, unexplained weight loss, pallor and exhaustion.
Significant risks factors may include congested, impoverished living situations, unsanitary areas, homelessness and regular contact with infected people. Other individuals who are at an increased risk are those who have silicosis, chronic renal failure diabetes mellitus, low body weight and weakened immune system.
As preventive measure, BCG vaccine is widely used around the world as it aids in the rick reduction of serious tuberculosis in children. Pharmacological treatment includes the combination of four antibiotics with medical supervision namely isoniazid, rifampin, pyrazinamide and ethambutol which is usually recommended for 6 to 9 months. Other treatment approaches are adequate rest, hospitalization in isolation rooms and surgery to remove damaged lung.
