5.2.2. Treatment of pulmonary TB in children and adolescents

Young children with TB usually have paucibacillary TB disease (TB disease forms with a lower burden of M. tuberculosis than is typical in adult-type cavitary TB disease) and are at lower risk for transmitting TB to other children or adults (6). School-aged children and adolescents, however, may have bacteriologically confirmed TB, sometimes with cavities on CXR (6).

3.2 BCG vaccination

BCG is a live attenuated bacterial vaccine derived from Mycobacterium bovis that was originally isolated in 1902 from a tuberculous cow. BCG has demonstrated significant effectiveness, but protection has not been consistent against all forms of TB in all age groups. BCG has also shown effectiveness in preventing leprosy (caused by Mycobacterium leprae) and Buruli ulcer (caused by Mycobacterium ulcerans) (31).
