We find that the novel A/H1N1 influenza viruses exhibit very low genetic divergence and suffer strong purifying selection among human population and confirm that they originated from the reassortment of previous triple-reassortant swine influenza viruses including genomic segments from both avian and human lineages with North American and Eurasian swine lineages. The longer phylogenetic branch length to their nearest genetic neighbors indicates that the origin of the novel A/H1N1 is unlikely to ...[more]
