Influenza has a large impact on the Canadian swine industry as it mutates quickly resulting in multiple strains. A genomic analysis was completed on 16 strains that were causing outbreaks in Canada. Once one of the viruses was being dealt with, often another strain would emerge starting the cycle again. Good vaccination protocols do not result in elimination of influenza in the barn, but rather the timing of the outbreaks are altered. It is important to understand the genes that are circulating in your own specific barn as every barn varies. This can help control influenza and prepare for possible future outbreaks.
