Global distribution of the H3N2 intra-subtype reassortants. Colors correspond to the reassortant lineage/clade colors in the maximum likelihood tree (see Fig. 1). Unique reassortants are represented by yellow. Non-reassortant viruses are transparent gray. N denotes the total number of genomes sampled from a region. Circle size is arbitrary for clarification purposes and is not proportional to N
