The dynamics analysis of geographical regions of the full-length genome sequences of field isolates from China sampled during the years 1985–2020 (A–D). Spatiotemporal dynamics of the full-length genome gene sequences of infectious bronchitis virus (IBV) among 20 localities. Bayes factor (BF) test for significant non-zero rates and regional transmission analysis (E). Curves show the among-country virus lineage transitions statistically supported with Bayes factor > 3 for all the IBV isolates in China. Curve colors represent corresponding statistical support (Bayes factor value) for each transition rate (inset).
