Figure 4. Pairwise SNP-distance distributions among genomes in the focal expanding North American genotype D8 lineage from study of whole-genome sequencing of measles virus from 2025 outbreak, Texas, USA. Violin plots show distributions of pairwise SNP distances within Texas, Utah, Arizona, and South Carolina and between Texas and each comparison jurisdiction. Embedded boxplots show medians (horizonal lines) and interquartile ranges (box tops and bottoms); whiskers indicate the most extreme values within 1.5x the interquartile range below the first quartile or above the third quartile. Wider sections of violins indicate greater density of pairwise comparisons. SNP, single-nucleotide polymorphism.
