Fig. 7: Temporal transmission dynamics of OL101:KL47 and O2v1:KL64 (2014–2019).

Recent intra- and inter-facility transmission pairs using pairwise single-nucleotide polymorphism (SNP) distances were identified by year. Circles indicate the proportion of pairs (y-axis) calculated by using various pairwise SNP distance thresholds (x-axis). A range of thresholds (14–25 SNPs; a gray area) were used in this study (see methods) to identify recent intra- and inter-facility transmission pairs for OL101:KL47 (the top two rows) or O2v1:KL64 (the bottom two rows).
