Phylogenetic overview of H9N2 HA in China from1994 to 2020. Left, shows a time-scaled phylogeny of H9N2 HA sequences sampled in China up to the end of June 2020, colored by the motif type in sites 127,135,145 and 146 of HA. The approximate position of vaccine strains is marked with different colored arrows (purple: A/chicken/Shandong/6/1996 (SD/96), green: A/chicken/Guangxi/55/2005 (GX/05), black: A/chicken/Jiangsu/WJ57/2012 (JS/12), red: A/chicken/Anhui/LH99/2017 (AH/17), blue: A/chicken/Fujian/11/2020). Right, the proportion of those same HA sequences containing the different types of motifs in different regions of China. Tree and visualization were generated using the Nextstrain platform (see Methods). Map data
