Overview
Tuberculosis (abbreviated as TB for 'Tubercle bacillus' or Tuberculosis is a common infectious disease caused by Mycobacterium tuberculosis. Tuberculosis most commonly involves the lungs as the organism thrives in high oxygen environments, but it can also cause disease in the central nervous system, the lymphatic system, the circulatory system, the genitourinary system, bones, joints and even the skin.[1] Over one-third of the world's population has been exposed to M. tuberculosis, and new infections occur at a rate of one per second.[2] Not all individuals exposed to the bacterium develop clinically overt tuberculosis infection; in fact, asymptomatic, latent TB infection discovered by screening is more common. Approximately, one in ten latent infections progresses to active (symptomatic) TB disease, which, if left untreated, carries mortality rates of up to 50%. Symptoms include shortness of breath, hemoptysis, fever, chills, night sweats, and weight loss. Several treatment regimens are available for the latent and active forms of TB. Classically, a prolonged course of 6-9 months of a single agent (rifampin or isoniazid) is administered to patients with latent TB, while a more aggressive course that consists of 4 major antituberculous agents (rifampin, isoniazid, ethambutol, pyrazinamide) is reserved for patients with active disease.
