AIM: The aim of our study was to determine the effectiveness of contact tracing for both @entity1907 ( @entity378 ). METHODS: The authors studied contact tracing in South East of Scotland, Edinburgh @entity378 Clinic, UK, for 3 years. New index cases of both @entity1907 were identified from reviewing @entity378 nurses records. @entity358 was excluded from all non-pulmonary cases. Active @entity378 was diagnosed as per the national @entity378 guidelines. Latent @entity378 was diagnosed based on history, tuberculin skin test and interferon y release assay. @entity378 contacts were identified from reviewing @entity378 nurses notes on index @entity378 @entity1 . A positive screening episode was defined as identification of either active or @entity9178 in a contact following relevant investigations. RESULTS: Total number of positive screening episodes for @entity1907 was 43.1% and @entity1907 was 26.1%. Of these, 78.8% were household contacts and 21.2% were casual contacts. CONCLUSION: Contact tracing in low-prevalence @entity378 countries, for both @entity1907 , is an essential intervention to identify and reduce the number of infected @entity1 that will progress to active disease. This is the key for effective @entity378 control.
