The origins of the 2009 influenza A (H1N1) pandemic in swine are unknown, highlighting
gaps in our understanding of influenza A virus (IAV) ecology and evolution. We review how …

A large diversity of influenza A viruses (IAV) within the H1N1/N2 and H3N2 subtypes
circulates in pigs globally, with different lineages predominating in specific regions of the …

The complex and unresolved evolutionary origins of the 2009 H1N1 influenza pandemic
exposed major gaps in our knowledge of the global spatial ecology and evolution of …

To determine the extent to which influenza viruses jump between human and swine hosts,
we undertook a large-scale phylogenetic analysis of pandemic A/H1N1/09 (H1N1pdm09) …

Swine influenza presents a substantial disease burden for pig populations worldwide and
poses a potential pandemic threat to humans. There is considerable diversity in both H1 and …

The diversity of influenza A viruses in swine (swIAVs) presents an important pandemic
threat. Knowledge of the human-swine interface is particularly important for understanding …

The capacity of influenza A viruses to cross species barriers presents a continual threat to
human and animal health. Knowledge of the human-swine interface is particularly important …

Influenza A viruses are important veterinary and human health pathogens that all share
many genetic characteristics. Wild birds are thought to be the primordial reservoirs of …

Emerging and re-emerging viral diseases are of great public health concern. The recent
emergence of Severe Acute Respiratory Syndrome (SARS) related coronavirus (SARS-CoV …

Novel H3N2 influenza viruses (H3N2v) containing seven genome segments from swine
