Abstract:
An analysis of 24 144 norovirus sequences from Asia and Russia deposited in GenBank between 1995 and 2023 was conducted,to understand the temporal and spatial variations in norovirus genotypes in these regions.Norovirus sequences from Asia and Russia were downloaded in FASTA format from GenBank for the years 1995-2023,and analyzed in Excel,R language,and GraphPad Prism for data visualization.The number of norovirus sequences submitted to GenBank increased annually from 2004 and peaked in 2015.Notably,China and Japan contributed 62.3%of all submitted norovirus sequences.These sequences encompassed 31 capsid genotypes(C-type),with GⅠ accounting for 9%and GⅡ accounting for 90%.Additionally,49 polymerase types(P-type)were identified,along with 68 combinations of CP types;among the analyzed recombinant sequences(4 460 entries in total),approxi-mately 41%belonged to three predominant recombinant strains:GⅡ.2[P16],GⅡ.4[P31],and GⅡ.4[P16].This analysis provides valuable insights into the distribution characteristics of norovirus genotypes across Asia and Russia over time,thereby supporting vac-cine design and evaluation efforts.
