Figure 6. Geographic distribution of each lineage and clade for A/H9 influenza viruses as part of a proposed global classification and nomenclature system for A/H9 influenza viruses. The heat map displays the number of sequences for each lineage and clade per country. Countries were ordered by their macro-region (upper panels). Each country displaying >1 sequence was colored on the map in green (Y lineage), blue (G lineage), or red (B lineage) (bottom panels).
