Human Infections with Novel Reassortant Influenza A(H3N2)v Viruses, United States, 2011

Emerging Infectious Diseases, 2012
During July–December 2011, a variant virus, influenza A(H3N2)v, caused 12 human cases of influenza. The virus contained genes originating from swine, avian, and human viruses, including the M gene from influenza A(H1N1)pdm09 virus.

H3N2 canine influenza virus-like particle vaccine with great protection in beagle dogs

Microbiology Spectrum
In 2016, a distinct branch of H3N2 canine influenza virus (CIV) emerged, which has mutations related to mammalian adaptation and has replaced previously prevalent strains. This branch poses a risk of zoonotic infection.

A Mutation Network Method for Transmission Analysis of Human Influenza H3N2

Viruses, 2020
Characterizing the spatial transmission pattern is critical for better surveillance and control of human influenza. Here, we propose a mutation network framework that utilizes network theory to study the transmission of human influenza H3N2. On the basis
