| surveillance for eurasian-origin and intercontinental reassortant highly pathogenic influenza a viruses in alaska, spring and summer 2015. | eurasian-origin and intercontinental reassortant highly pathogenic (hp) influenza a viruses (iavs) were first detected in north america in wild, captive, and domestic birds during november-december 2014. detections of hp viruses in wild birds in the contiguous united states and southern canadian provinces continued into winter and spring of 2015 raising concerns that migratory birds could potentially disperse viruses to more northerly breeding areas where they could be maintained to eventually s ... | 2016 | 27036114 |
| evidence for common ancestry among viruses isolated from wild birds in beringia and highly pathogenic intercontinental reassortant h5n1 and h5n2 influenza a viruses. | highly pathogenic clade 2.3.4.4 h5n8, h5n2, and h5n1 influenza a viruses were first detected in wild, captive, and domestic birds in north america in november-december 2014. in this study, we used wild waterbird samples collected in alaska prior to the initial detection of clade 2.3.4.4 h5 influenza a viruses in north america to assess the evidence for: (1) dispersal of highly pathogenic influenza a viruses from east asia to north america by migratory birds via alaska and (2) ancestral origins o ... | 2016 | 26944444 |
