Abstract
Tuberculosis (TB) remained the single leading infectious cause of ill health and death globally until the COVID-19 pandemic occurred. Tuberculosis contributes significantly to childhood mortality of about 16% among HIV-negative children worldwide. Childhood tuberculosis is a significant epidemiological tool as childhood TB represents recent transmission in the community and reflects the presence of an infected adult. Previously clinical research, diagnostic methods, and therapeutic discoveries have focused on adult tuberculosis to the neglect of childhood tuberculosis. Limited pediatric surveillance data, poor case ascertainment, and limited resources and capabilities have hindered the attainment of the true burden of childhood tuberculosis in countries with high tuberculosis disease burden. The difficulty in characterising the true burden of tuberculosis is mainly from the difficulty in obtaining adequate and reliable diagnostic samples to confirm TB in children. Sputum induction has proven to be feasible and effective in several LMIC settings. Gene Xpert MTB/Rif; polymerase chain reaction, performed on induced sputum samples is more sensitive in the detection of paucibacillary TB in children as compared to sputum smear testing. This allows for early diagnosis and timely initiation of therapy. It is necessary that we continue to utilize the available tools to improve TB diagnosis in children and ensure we meet End TB and SDG goal 3 targets on time
