SARS-CoV-2: New recombinants designated XG, XH, XJ, XK and XL

BA.1, BA.2, Coronavirus, Delta, Deltacron, Infection, Omicron, Recombinants, Recombination, Transmission, XG, XH, XJ, XK, XL

SARS_CoV-2 recombinants are being designated almost on a daily basis now. These are the latest strains:

XG: New lineage with 140 new sequence designations. Potential BA.1/BA.2 Recombinant Lineage with Likely Breakpoint at NSP3 (107 Sequences in Denmark, UK, US and Germany as of 2022/03/02). Link

XH: new lineage with 42 new sequence designations. Potential BA.1/BA.2 Recombinant Lineage with Likely Breakpoint at NSP5/NSP6 (43 Sequences in Denmark). Link

XJ: new lineage with 17 new sequence designations. BA.1/BA.2 recombinant lineage in Finland [66 seq as of 2022-03-25]. Link

XK: new lineage with 15 new sequence designations. Potential recombined BA.2-BA.1.1 lineage in 22 (1.4%) sequences in Roeselare, Belgium characterized by ORF1b:Q866R and ORF1a:R1628C with BA.2 background and ORF1a (2832-10029) and ORF1b (160464-18163) from BA.1.1 (ORF1b:Q866R). Link

XL: new lineage XL with 38 new sequence designations. Potential BA.1/BA.2 Recombinant Lineage with Likely Breakpoint at NSP3 (38 Seqs in UK as of 2022-03-16). Link

It’s fairly safe to say we can expect many more virus recombinants in the future…

 

 

UK: XE may have a growth rate ~10% greater than Omicron BA.2 *1 UPDATE*
