U.S. Variant Proportions by Common Name Sources: CDC, Cov-Lineages, NYITCOM, others [ beadsland on Ko-fi ] Reskin of CDC's Variants Nowcast, and any significant variants in GISAID not broken out by CDC. Five bar-style tree-charts, for fortnights through 5/25–6/7. Legend of last fortnight, organized by subheadings of color-grouped families and convergent clusters. Percentages overlay each color key, reflecting share as of most recent tree-chart. WHO-Vaccine-Target JN.1 accounts for over three fifths. JN.1.11 for over two fifths. For 5/11–5/24, packed bubble charts fill single-variant tiles, reflecting GISAID detail not shown by CDC's Nowcast.
