A consensus sequence for the region was derived by running 25183 NS1 sequences through the Analyze Sequence Variation (SNP) tool on the Influenza Research Database –website (http://www.fludb.org). Prevalence of each amino acid is indicated as a total number and percentage within all the analyzed sequences.
