TL;DR: It is shown that H7 viruses probably transferred from domestic duck to chicken populations in China on at least two independent occasions and subsequently reassorted with enzootic H9N2 viruses to generate the H7N9 outbreak lineage, and a related previously unrecognized H7n7 lineage.

TL;DR: It is shown that H7N9 viruses have spread from eastern to southern China and become persistent in chickens, which has led to the establishment of multiple regionally distinct lineages with different reassortant genotypes.

TL;DR: Wang et al. as discussed by the authors found that over 50% of pigs tested were seropositive for one or more H1 influenza viruses, most commonly pdm/09-like viruses.

TL;DR: From extensive surveillance of SIVs over a 38-month period in southern China, it was found that although neither complete pdm/09 viruses nor their surface genes could persist in pigs, their internal genes did persist and became predominant, potentially replacing those of the enzootic SIV lineages.

TL;DR: 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.
