Human seasonal H3 clade 3C3a influenza A viruses (IAV) were detected four times in U.S. pigs from commercial swine farms in Michigan, Illinois, and Virginia in 2019. To evaluate the relative risk of this spillover to the pig population, whole genome sequencing and phylogenetic characterization were conducted, and the results revealed that all eight viral gene segments were closely related to 2018-2019 H3N2 human seasonal IAV. Next, a series of
