Genotyping and phylogeographic dynamics of coxsackievirus A16.

ABSTRACT: Coxsackievirus A16 (CV-A16) is one of the major pathogens of Hand, Foot and Mouth disease. Here, we analyzed 287 full-length genome sequences of CV-A16 found worldwide from 1994 to 2019 to see the genomic evolution characteristics. Full-length genome-based phylogenetic tree divided the viruses into five different genotypes, G-a to G-e. The CV-A16 strains circulating in China dominate G-a and G-c, but can also be found in other genotypes including G-b and G-e. Phylogeographic analysis showed a high diversity of CV-A16 distribution. In addition, recombination was shown to drive the genomic evolution of CV-A16 during past decades. However, the structural proteins still remain relative conserved while there is extensive genomic recombination. This study updates the phylogenetic and phylogeogra
