Reassortment between Influenza B Lineages and the Emergence of a Coadapted PB1–PB2–HA Gene Complex
Reassortment between Influenza B Lineages and the Emergence of a Coadapted PB1–PB2–HA Gene Complex
Influenza B viruses make a considerable contribution to morbidity attributed to seasonal influenza. Currently circulating influenza B isolates are known to belong to two antigenically distinct lineages referred to as B/Victoria and B/Yamagata. Frequent exchange of genomic segments of these two lineages has been noted in the past, but the …
