Granular details #Global #20DayTrends

This analysis includes all designated #SARSCoV2 sequences submitted to @GISAID with sample collection dates on or after 05/15/2023 (6,574 sequences) Image
In Silico Immune escape and ACE2 receptor binding scores (relative to BA.2)*

Data is intended to prioritize select lineages to generate rapid laboratory experiments to gauge immune escape and ACE2 binding affinity.

[Credits in the legend] *Only Spike RBD mutations considered Image
Thanks to all the countries that are still supporting #SARSCoV2 testing and rapidly submitting sequences to public databases like @GISAID

#China and #Canada have submitted more sequences than #USA with sample collection dates in the last 20 days! Image

Airport sequences constitute ~12.4% of sequences with sample collection dates in the last 15 days (#15DayTrends)

Its going to be a three way race to outcompete XBB.1.5*: XBB.1.9* vs XBB.1.16* vs XBB.2.3*

As of now, XBB.1.16* family looks to over take everything else!
