DENV genomic clustering is spatially and temporally dependent. Proportion of all dengue case pairs, regardless of serotype, that belong to the same genomic cluster, stratified by their temporal proximity (time between illness onset: up to 1, 1–2, 2–3, 3–6, 6–12, or > 12 months) and spatial proximity (distance between primary residence: non-overlapping bins of 100 m up to 500 m, then 500–1000 m or > 1000 m. Bins are labelled at their upper bound). Error bars represent 95% confidence intervals. The horizontal dotted line represents the overall proportion of dengue case pairs that belong to the same genomic cluster, regardless of spatial or temporal proximity.
