title: Antigenic and genetic characterization of a European avian-like H1N1 swine influenza virus from a boy in China in 2011.
abstract: Cross-species transmission of influenza A viruses from swine to human occurs occasionally. In 2011, an influenza A H1N1 virus, A/Jiangsu/ALS1/2011 (JS/ALS1/2011), was isolated from a boy who suffered from severe pneumonia in China. The virus is closely related antigenically and genetically to avian-like swine H1N1 viruses that have recently been circulating in pigs in China and that were initially detected in European pig populations in 1979. The isolation of JS/ALS1/2011 provides additional evidence that swine influenza viruses can occasionally infect humans and emphasizes the importance of reinforcing influenza virus surveillance in both pigs and humans.
