*Lineages shown correlated with those shown Figure 2. Shading indicates grouping of 4 reassortant types. Variant origin (bottom rows) was derived from phylogenetic trees and indicated as SC (southern China) and EC (eastern China). Three of the 4 reassortant genomes were also detected through environmental surveillance. M, matrix; NP, nucleoprotein; NS, nonstructural; PA, polymerase acidic; PB, polymerase basic.
