The epidemiology of influenza in the North American swine population has changed since the <\/span>emergence of a triple-reassortant H3N2 influenza virus. Although seen previously in North America, the Ontario swine population had likely been free of viruses of the reassortant H3N2 lineage until 2005. The <\/span>objective of this study was to investigate the frequency and distribution of exposure to H1N1 and H3N2 <\/span>subtypes in the Ontario finisher pig population prior to and after the H3N2 outbreak that occurred in 2005. This included investigating prevalence and spatial distribution of positive herds, assessing proportion of<\/span><\/p>\n random variation at different hierarchical levels, and evaluating selected demographic factors and management <\/span>procedures as potential risk factors.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":" The epidemiology of influenza in the North American swine population has changed since the emergence of a triple-reassortant H3N2 influenza virus.
