The page it took me to, had the header
Mutations in Variants of Concern (VOC) or Interest (VOI) identified from GISAID sequences (Feb 5, 2021)
And I didn't see Delta mentioned.
I know, 404 Error Coffee not found.
Where's the mention of Delta and its genome?
Post a pic of the page and its URL please?
you answered your own question. That particular tracker is current thru Feb 5, 2021. Delta was detected in OK, Mar/Apr 2021 but wasn’t listed as a VOC until May 4, 2021. Genomic tracking for B.1.167/AY, scroll down to bar graph and highlight variant on right to change bar graph:
