Host switch events of influenza A viruses (IAVs) continuously pose a zoonotic threat to humans. In 2013. swine-origin H1N1 IAVs emerged in dogs soon after they were detected in swine in the Guangxi province of China. This host switch was followed by multiple reassortment events between these H1N1 and previously circulating H3N2 canine IAVs (IAVs-C) in dogs. https://parisnaturalfoodes.shop/product-category/advanced-b-complex/
