H3N2 canine influenza virus emerged in South Korea in 2007 and subsequently spread to China and Thailand, causing epidemic or endemic respiratory diseases in dogs. Through intermammalian species transmission, the virus has also infected cats. However, no direct evidence of significant genetic evolution has been reported since its first emergence. Here, we describe in depth the genetic and molecular characteristics of the ancestral strain (i.e., the first virus isolate from South Korea) of the H3N2 canine influenza virus currently circulating in East Asia.
