During swine influenza surveillance from 2007 to 2008, 10 H1N1 viruses were isolated and analyzed for their antigenic and phylogenetic properties. Our study revealed the emergence of avian-origin European H1N1 swine influenza virus in China, which highlights the necessity of swine influenza surveillance for potential pandemic preparedness.
