Abstract BackgroundTuberculosis (TB) in children is an indicator of ongoing transmission so source-case investigations to ascertain the source of infection are essential. All cases should be notified to the local health protection team (HPT) to facilitate a public health risk assessment.MethodsPaediatric TB cases notified between January and December 2017 were identified from the London TB register (LTBR) and subsequently searched on the local HPT database ('HPZone').Results35 cases were identified of which 14 had been reported to the HPT. Median age was 15 years (range 2-17) and 64% were female. 10/14 (71%) were laboratory confirmed and the median duration of symptoms was 4 weeks. 5/14 (36%) had been exposed to a recent known active case whereas no source was found for 9 (64%). All cases had a public health risk assessment conducted and all 14 households, and 6 educational institutions, were screened. Of the 52 close social and household contacts, 5 (10%) were found to have active TB and 13 (25%) latent TB. 95 students were screened with 1 requiring treatment for active TB and 4 were offered latent TB treatment.DiscussionDiagnosis and public health management of paediatric TB remains challenging. In our cohort, less than half of the cases were notified to the HPT. The importance of notifying these cases should be re-iterated to TB teams so that contact tracing and source-case investigations can be employed to interrupt ongoing transmission and to continue the downward trend in TB incidence being observed in the UK.
