Visualization of primary transmission sub-cluster definition. Using geospatial and epidemiological data, we estimated the size of TB transmission sub-clusters within a MIRU-VNTR genotypic cluster. Participants with the same M. tuberculosis genotype (black circles) were considered a genotypic cluster (\(Y = 13\)). Participants were in a transmission sub-cluster if they were in the same SaTScan geospatial cluster (colored circles) or identified through an epidemiological link (solid lines). This fictitious example represents a genotypic cluster of size 13 with two transmission sub-clusters of size 8 (purple) and 3 (pink) and two isolated cases. White circles represent TB cases with a different MIRU-VNTR profile and are not included in the cluster definitions.
