Abstract

Collaborative genomic and epidemiological investigations identified a tuberculosis outbreak in Vienna as part of a multi-country cluster comprising 57 foreign-born cases of Mycobacterium tuberculosis ST215/Beijing 2.2.1 notified 2021-2025. While 14 of 16 cases in Vienna were considered autochthonous, the diverse geographic origin of clustered cases across nine European countries suggests a common transmission source, possibly linked to migratory routes. Cross-border data exchange and integrated genomic analysis are essential for identifying transmission dynamics in tuberculosis clusters affecting mobile populations.

Keywords: Cluster; Cross-border; Genomic surveillance; Tuberculosis; Whole Genome Sequencing.
