Objectives: We reported the incidence and associated factors of extrapulmonary tuberculosis (EPTB).
Design: A retrospective cohort study.
Setting: Brunei Darussalam, an intermediate tuberculosis (TB)-burden country with stagnating annual TB rates.
Introduction: We evaluated the yield of tuberculosis (TB) contact investigation in Brunei Darussalam, and identified the associated factors for latent TB infection (LTBI) diagnosis, as well as for initiating and completing LTBI treatment.
Methods: Data were extracted and digitalised for all close contacts of pulmonary TB (PTB) cases at the National TB Coordinating Centre from January 2009 to December 2018. Generalising estimating equations logistic regression models were used to determine the associated factors.
