TB is one of the most frequent infectious diseases in humans, more in developing countries like us. The disease is mostly caused by Mycobacterium Tuberculosis organism. The disease usually affects the lungs, although in up to one-third of cases other organs are involved. If properly treated, tuberculosis caused by drug-susceptible strains is curable in virtually all cases. If untreated, the disease may be fatal within 5 years in more than half of cases. Transmission usually takes place through the airborne spread of droplet nuclei produced by patients with infectious pulmonary tuberculosis.
Tuberculosis is most commonly transmitted from a patient with infectious pulmonary tuberculosis to other persons by droplet nuclei, which are aerosolized by coughing, sneezing, or speaking. Several studies of close contacts have clearly demonstrated that tuberculosis patients whose sputum contains bacteria visible by microscopy play the greatest role in the spread of infection.
