Abstract excerpt

BACKGROUNDIn tuberculosis (TB) surveillance, genomics is mainly used to identify TB patient clusters; growing clusters are commonly attributed to ongoing transmission events.AIMThis study's objective was to explore other factors, in addition to ongoing transmission, contributing to cluster expansion.METHODSThe study population included all 1,886 culture-positive TB cases diagnosed within the whole Almería...
