About this release

This release by Public Health Scotland (PHS) of quarterly official statistics in development presents provisional data from the national enhanced surveillance system for tuberculosis (TB) notifications in Scotland. This release present provisional quarterly data up to quarter 4 (October to December) of 2025, in addition to the annual TB surveillance report which is published by PHS.

The TB quarterly report is now based on data extracted from the newly adopted UK National Tuberculosis Surveillance System (NTBS) and therefore there are minor changes in historical data. Previously, Scottish TB surveillance data was captured by the Enhanced Surveillance of Mycobacterial Infections (ESMI) system. NTBS is a dynamic data source and statistics released are provisional and subject to validation and future planned revisions. These revisions do not affect the overall interpretation or conclusions to be drawn from the previously published data.

The content of these reports will be reviewed and developed over time following feedback from stakeholders and user engagement. If you would like to provide any feedback, please contact PHS respiratory bacterial team phs.TB@phs.scot.
