2 new sequences Australia and California
One more from Singapore.
One more from South Korea
3 new sample from Wales and one from England not yet on GISAID(England/PHEC-YYE4DU3/2023|2023-05-24)
Quite striking that this keeps popping up here and there without a geographical clear trend if not that it is sequenced in countries with still ongoing good surveillance, this may hint to a good prevalence somewhere in an undersampled region .
cc @corneliusroemer please take a look at this.
Tree: (now it is clear that ORf1a:A3456T (NSP5_A193T) is just a branch of it so i have edited the main proposal: https://nextstrain.org/fetch/genome.ucsc.edu/trash/ct/subtreeAuspice1_genome_12203_1967c0.json?label=id:node_6688471
interestingly the samples from Wales carry S:G184S
Just to take note that one little but interesting node of XBB.1.9.1 is defined by S:L452R and ORF7a:V104L and it has been already found in US and Japan suggesting maybe a wider than seen circulation.

Note: EDITED the NSP5_A193Tis just a branch of it more samples came after the first samples not carrying that mutation, so i deleted it from the main proposal
NSP5_A193T was mentioned in this report : https://www.publichealthontario.ca/-/media/Documents/nCoV/ipac/2022/06/sars-cov2-protease-mutations-paxlovid-resistance.pdf?sc_lang=en that didnt find a strong link to Paxlovid Resistance, tough recording its sporadic appearance in the samples analyzed by this report.
