Abstract
The 2009 pandemic influenza virus (pdm/09) has been frequently introduced to pigs and has reassorted with other swine viruses. Recently, H3N2 reassortants with pdm/09-like internal genes were isolated in Guangxi and Hong Kong, China. Genetic and epidemiological analyses suggest that these viruses have circulated in swine for some time. This is the first evidence that swine reassortant viruses with pdm/09-like genes may have become established in the field, altering the landscape of human and swine influenza.
