#SARSCoV2 #Omicron family quickly swells to 900+ #sublineages!
Add another 203+ recombinant lineages (w/ Omicron partner)
Currently, we are watching "Omicron" Great-Great-Great grand kids.. especially the recombinant families..
Recombinants have outcompeted others globally!

#SARSCoV2 Variant Nicknames are very useful in communication especially in the social media

Executive Summary The SARS-CoV-2 pandemic has highlighted the importance of clear communication that makes information accessible to a wide audience. Efforts to communicate about the evolution, diversity, … Continued
Not every lineage is worth naming or designation as VOI/VOC (@WHO) & not every group of lineages is worth a nickname by #VariantTrackers.
High flying lineages from #Collection24 from @wolfeagle1989 @Asinickle1 @siamosolocani
https://cov-spectrum.org/collections/24.
Calling all of them as #Omicron doesn't help
High-flying lineages in
#India: XBB.1.16,
#China BA.5.2.48* & BF.7.14*
#UnitedStates: XBB.1.5
(you get the idea!)
Globally 692 Omicron lineages are in circulation (at least 1 sequence reported) in the last 60 days (accounting for reporting delays)
Out of which only 15 lineages accounted for 1% or more sequences submitted globally
Currently XBB.1.5 tops the chart
