Genetic and antigenic characterization of an expanding H3 influenza A virus clade in US swine visualized by Nextstrain

2021-11-19

Abstract excerpt

Defining factors that influence spatial and temporal patterns of influenza A virus (IAV) is essential to inform vaccine strain selection and strategies to reduce the spread of potentially zoonotic swine-origin IAV. The relative frequency of detection of the H3 phylogenetic clade 1990.4.a (colloquially known as C-IVA) in US swine declined to 7% in 2017, but increased to 32% in 2019. We conducted phylogenetic and ph...
