Omikron-delta-omikron tyyppinen XBC rekombinantti koostuu BA.2* /B.1.617.2*/BA.2* varianttiosista ja alalinjat XBC.1.6* vaikuttavat lisääntyvän.

https://github.com/cov-lineages/pango-designation/issues/2057 

Designaation ovat jo  saaneet jo alalinja XBC.1.6.1, XBC.1.6.2 , XBC.1.6.3 ja XBC.1.6.4 , vaan vielä löytyy lisää XBC.1.6 linjalle  alalinjoja ja  selvitellään niiden kasvuedellytyksiä.

After the recent designation of XBC.1.6.4 i am noticing new branches with very recent samples collected during May. i would like to share them with corneliusroemer , i suppose he is aware of them but better to have a reminder here , looking at how fast XBC.1.6 is growing as share of total sequences in Australia: XBC.1.6 > G3671A (ORF1a:E1136K) Gisaid : G3671A ,C12733T > 76 seqs (63 of them collected in May) XBC.1.6 > T8707C, C26735T Gisaid : C26735T, C10156T,T8707C > 51 seqs (31 of them collected in May) XBC.1.6 > C1594T Gisaid C1594T,C12733T,C2334T, G3606T > 50 seqs ( 28 seqs of the, collected in May) XBC.1.6 > C10833T (ORF1a:A3523V) Gisaid: C12733T,G3606T,C10833T 32 seqs (23 seqs out of 30 collected in May

 to fast comparing all of them to parental XBC.1.6:
