Avian influenza at both ends of a migratory flyway: characterizing viral genomic diversity to optimize surveillance plans for North America
Abstract Although continental populations of avian influenza viruses are genetically distinct, transcontinental reassortment in low pathogenic avian influenza (LPAI) viruses has been detected in migratory birds. Thus, genomic analyses of LPAI viruses could serve as an approach to prioritize species...
