GE.1 + S:F456L (33 seqs emerged in India-MH , 10 countries) #714

Closed FedeGueli closed 11 months ago

FedeGueli commented 1 year ago

Note that also GE.1 acquired S:F456L recently in India and likely it is way bigger than the XBB.2.3.8 one proposed in #651

i just noticed that the entire branch with Orf1a:G519S has interesting samples pointing to a sustained undersampled circulation of the parental of the lineage proposal here. For example the query: G5156T, G11555A, C16173T, A22976C finds one sample with S:I472L and S:D215G. Residue 473 was recently highlighted by J.Bloom as one of the hotspot to evade recent XBB immunity on a xbb background.

First exportation to France collected on 21-08.

+1 EPI_ISL_18239122 was a traveller from India caught by surveillance in US airports. This makes me think this has gained some prevalence there.

FedeGueli commented 1 year ago

it represents around 10% of samples in MH in September. 4 samples from MH,India 1 sample intercepted from Us Airport surveillance in a traveller from India.

ping @corneliusroemer local (India) but interesting XBB.2.3+ 456-478.

FedeGueli commented 12 months ago

+3 Denmark, Canada , Gujarat

FedeGueli commented 11 months ago

21 , 8 countries

FedeGueli commented 11 months ago

+3 Canada

Now 33 ,6 from November, but interesting coming from 5 different countries, one intercercepted by GBW airport surveillance in a traveller coming from UAE, i m proposing it. it represents around 5% of sequences from or related to India after September 1.
