<s>[INST] How is TB spread? [/INST] Tuberculosis (TB) is passed from person to person through the air. Individuals with pulmonary (lung) TB can propel aerosols containing Mycobacterium tuberculosis complex organisms into the air when they cough, sneeze, sing, speak or spit. Persons who then inhale these aerosols can become infected. Factors that determine the probability of infection include the immune status of the exposed individual, infectiousness of the TB contact and the proximity, frequency and duration of exposure.
