Tuberculosis (TB) is an acute or chronic bacterial infection found most commonly in the lungs. The infection is spread like a cold, mainly through airborne droplets breathed into the air by a person infected with TB. The bacteria causes formation of small tissue masses called tubercles. In the lungs these tubercles produce breathing impairment, coughing and release of sputum. TB may recur after long periods of inactivity (latency) if not treated adequately. Many variations of TB exist and are distinguished by the area of the body affected, degree of severity and affected population. This disease today is considered curable and preventable. It is very rare in the United States but is on an upsurge.
