Why is this important? > Many influenza experts are concerned about enhanced zoonotic potential for H5N1 viruses that might spill over and establish ongoing infections in swine populations. Swine already endemically carry many human spillover H1 and H3 viruses, and pigs are prone to easily reassort viral segments when co-infected with 2 viral strains. This potential reassortment between a mammalian-adapted H5N1 and swine-human H1-H3 / N1-N2 endemic viruses in commercial production swine is a potential shortcut to a fully adapted H5 human pandemic strain[0].
