Spatiotemporal dynamics of LX4-type infectious bronchitis virus (IBV) isolates among different localities (A–D). 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 LX4 genotype IBV isolates in the world.
