Tuberculosis is a chronic disease that mainly affects the lungs, but can also affect other parts of the body like the spine. Tuberculosis is an infectious disease caused by the bacterium called Mycobacterium tuberculosis. The bacteria that cause TB spread from person to person through small droplets released into the air by coughing and sneezing. TB infections in developed countries began to increase in 1985. In the United States, tuberculosis began to decline in 1993 thanks to a strengthened control program but remains a concern.
Many strains of TB are resistant to the drugs most commonly used to treat this disease. People with active TB will need to take several types of medications for several months to eliminate the infection and prevent the development of antibiotic resistance. It is manifested by following signs and symptoms
- Coughing with blood.
- Chest pain or narrowness of chest
- Unintentional weight loss
- Night Sweats
