Maximum-clade credibility tree showing the time of emergence from humans and divergence of swine influenza A and influenza A(H1N1)pdm09 virus among swine populations in Australia. Numbers 1–10 denote inferences of individual introductions from humans to swine, and virus names are colored by state of collection: red, New South Wales; blue, Queensland; green, Victoria; purple, Western Australia. Time-scaled phylogenies were estimated by using the uncorrelated log-normal relaxed clock model (11) in
