Phylogenetically estimated neutral rates and fitness effects of mutations to influenza proteins
By constructing phylogenetic trees from over 100,000 influenza sequences, this study estimates site-specific neutral mutation rates and fitness effects across the viral proteome, revealing significant variation among mutation types, strong cross-viral correlations with SARS-CoV-2 and HIV, and providing a comprehensive, interactive resource for understanding how mutation and selection shape influenza evolution in nature.
