Introduction: Recognition and epidemiological control of childhood and adolescent tuberculosis (TB) is essential to achieve effective control of TB in general as it presents high risk for transmission in the community. The aim of the study is to provide a descriptive and analytic overview of the trends in childhood and adolescent TB notifications and treatment outcomes and to identify factors associated with treatment success in a twelve-year period in Serbia., Methodology: We performed a retrospective trend analysis and analysis of treatment outcomes of 596 child and adolescent TB cases notified in Serbia in the period 2005-2016 from all health facilities, as well as logistic regression analysis to identify predictors of treatment success., Results: Factors independently associated with treatment success were: new TB (OR=2.60; 95% CI: 1.45-3.74), male sex (OR=2.55; 95% CI: 2.09-3.00), pulmonary TB (OR=3.34; 95% CI: 2.34-4.34), comorbidities (OR=2.58; 95% CI: 2.24-2.91), age below 5 years (OR=0.37; 95% CI: 0.32-0.43), and social vulnerability (OR=0.40; 95% CI: 0.34-0.46)., Conclusions: In order to improve TB treatment outcomes among children and adolescent population in Serbia, it is important to focus on female, age group 5-18, EPTB, retreatment cases and socially vulnerable groups., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2021 Maja B Stosic, Lidija Sagic, Danijela Simic, Verica Jovanovic, Violeta Rakic, Tatjana Adzic Vukicevic.)

Introduction: Between February and November 2016, 17 tuberculosis (TB) cases were identified among high school students in Novi Pazar, Serbia. The objectives of our study were to describe the outbreak, to identify potential risk factors and to evaluate the applied control measures., Methodology: The outbreak was described by time, person and place. A retrospective cohort study was conducted. Attack rates, unadjusted relative risks (RR) and 95% confidence intervals (CI) were calculated. Multiple log-binomial regression analysis was performed to calculate adjusted RR., Results: Sixteen of the total 17 cases occurred among grade 3 students, AR 5.5%. Previous TB family history, (RR = 5.29; 95% CI = 1.63-17.12), spending time with a known TB case at school (RR = 5.38; 95% CI = 1.48-19.55) and exposure to secondhand smoke (RR = 3.37; 95% CI = 1.11-10.29) were all significantly and independently associated with the occurrence of TB., Conclusions: Delayed diagnosis and reporting resulted in delayed initiation of the contact investigation and non-identification of latent TB cases probably favored the occurrence of this outbreak in a low incidence country. Public health authorities should consider revising the existing guidelines, promoting inter-sectorial collaboration and increasing awareness of public health professionals., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2019 Maja B Stosic, Dragana Plavsa, Nikoletta Mavroeidi, Dragana Jovanovic, Violeta Vucinic, Goran Stevanovic, Lidija Sagic, Sefadil Spahic, Uros Rakic, Anita Grgurevic.)
