Sars-2 viruksen Iota-variantti (B.1.526) alalinjoineen

Table 1 | Summary of lineage & sub-lineages

Lineage	Most common countries	Earliest date	# designated	# assigned	Description	WHO Name
B.1.526	United States of America 97.0%, Ecuador 1.0%, Puerto_Rico 1.0%, Canada 1.0%, Spain 0.0%	2020-01-28	253	39831	A lineage predominantly circulating in New York but with a few exports to other countries. Characterised by spike mutations T95I and D253G, plus others. The most frequent spike mutation pattern is L5F T95I D253G E484K D614G A701V, with a smaller fraction having S477N instead of E484K. Spike mutation E484K is present in about half of this lineage (as of 2021-02-10) - Very possible not all new additions carry T95I and D253G (someone should check this, e.g. for USA/NY-Wadsworth-21008455-01/2021 and Aruba/AW-RIVM-11403/2021)	Iota
B.1.526.1			0	0	Lineage reassigned. Withdrawn: Issue 45. New York. Sublineage of B.1.526 (with spike mutations T95I and D253G) that appears to have several more unique mutations.
B.1.526.2			0	0	Lineage reassigned. Withdrawn: Issue 45. New York. Sublineage of B.1.526 (with spike mutations T95I and D253G) that appears to have several more unique mutations.

B.1.637	United States of America 98.0%, Puerto_Rico 1.0%, United Kingdom 0.0%, Dominican_Republic 0.0%, Suriname 0.0%	2020-10-09	36	12372	Added as B.1.526.1 15 Mar 2021, but turned out not to be a descendant of B.1.526; was folded into B.1.526 from 14 Jun - 18 Aug 2021; now a separate lineage to leave B.1.526 more congruent with Iota (Nextstrain 21F / original B.1.526); pango-designation issue #154
