title: Swine to human transmission of reassortants of pandemic (H1N1) 2009 and endemic swine influenza viruses: Abstract.
abstract: To gain insight into the possible origin of a new reassortant influenza A virus between pandemic (H1N1) 2009 and endemic swine viruses that has jumped the species barrier and caused a few infections among humans in Indiana and Pennsylvania recently, we analyzed all full genome sequences related to this virus and report its evolutionary history, but failed to determine how the virus had emerged simultaneously in two geographically distinct areas.
