Evidence I call LB.1.3 the "global" branch of LB.1 because it seems to come disproportionately from travel sequences. The xtremely unusual 2-nuc S:Y660R mutation caught my eye here. S:K147E has been advantageous in the past and is another mutation increasing NTD's negative charge, which is a trend that's been going on for a long time now and shows no signs of slowing.

The most closely related sequence is a travel sequence from Qatar collected in the US.

Ping @corneliusroemer it could be a new thing.

+2 in two travellers from Germany (same day but different samples)

ryhisner commented 3 months ago

One of these showed up in British Columbia, Canada, so this one's skipping oceans now.

10 Seqs 6 countries not slow at all pleaase propose it: https://cov-spectrum.org/explore/World/AllSamples/Past3M/variants?%2FAllSamples%2FPast3M%2Fvariants%3FnextcladePangoLineage=JN.1*&nextcladePangoLineage=JN.1*&nucMutations1=T23540C%2CA23541G%2CG27261T&analysisMode=CompareToBaseline&

+2 France one of them from a new region of France : Cholet (Loire)

DailyCovidCases commented 3 months ago

Still 12 seqs: nextclade

FedeGueli commented 2 months ago

20 seqs from 9 countries.

To be noticed that 5/9 french samples come from inpatients. could it be a BQ.1.2.2 thing?

aviczhl2 commented 2 months ago

30 seqs now.

FedeGueli commented 2 months ago

31 with two branches one mainly from France, the other more international, still i don't think it is fast enough to compete. A couple of samples have no 147E
