In our study, we isolated and characterised two new Senecavirus A (SVA) isolates in Sichuan Province, China. Phylogenetic analysis of both the SVA full-length genomes and the VP1 genes revealed that the two new SVA isolates are more closely related to previous Chinese strains and US strains. The most variable isolate, SVV-SC-01, showed a significant difference from previous SVA strains, and it was identified as a recombinant using several algorithms. Study findings indicate that the SVA virus in China is constantly evolving and new SVA variants may have emerged. Hence, we must take effective measures to prevent further spread of SVA. This report provides evidence that SVA infection of pigs has occurred in Sichuan Province, and the results will contribute to our understanding of the genetic characteristics and recombinant events of SVA in China.
