Transmission of descendants of the 2022 outbreak lineage B.1 is ongoing in 2024. The new lineage designations aim to capture current circulation (since July 2024), most of which has been concentrated into B.1.20 and C.1.1 - at least based on publicly available genomes which are predominantly from the US, Germany, Portugal, and Australia.
The newly designated lineages are B.1.23; D.1 (B.1.6.1); E.1, E.2, E.3 (all children of C.1.1); and F.1, F.2, F.3, F.4, F.5, and F.6 (children of B.1.20). With these designations, the B.1 descendants are more clearly distinguished from each other.
D.1 (B.1.6.1) is from #41
F.1 (B.1.20.1) is from #40
F.2 (B.1.20.2) is from #39
E.1-3 (C.1.1.1-3) are from #44
B.1.23 is from #43
