Epidemiology of extrapulmonary tuberculosis in Brunei Darussalam: a retrospective cohort study.

Despite being generally non-infectious and less recognised than PTB, understanding EPTB epidemiology is important as it also contributes to the overall TB burden in a country. Examining EPTB cases by their specific anatomical site would provide more information on risk factors. Raising public awareness on the EPTB symptoms and that TB affects lungs and other parts of the body could promote early health seeking behaviour and early EPTB diagnosis.
