Evolutionary analysis based on SARS CoV-2 variant BA.5.2. A) Phylogenetic tree based on 2,407 genome sequence of the BA.5.2 variant from all countries. The red dot represents the genome collected from China, and the black dot represents the sample collected from other countries. B) Phylogenetic tree based on genomes containing BA.5.2 genomes collected from different provinces in China (showed in different colored blocks). The collection date ranged from September 2022 to January 2023.
