TB is usually transmitted through breathing the bacteria that a TB-active person has dispersed in the air after coughing. Transmission of the disease is usually associated with prolonged contact with a TB active individual. Casual exposure to an active TB patient is not usually associated with transmission, however, it cannot be ruled out.
Transmission of disease requires an active patient and a susceptible host.
People with active TB disease must be diagnosed and treated. Direct observed therapy is recommended to ensure that the patient completes their therapy. The remaining infection in the patient develops resistance to the treatment drugs therefore requiring different drug combinations for longer periods. Typical treatment for TB involves several drugs to be taken for at least 6 months. An active TB patient has viable TB bacteria in their sputum which can be released in the air when they cough.
