Granular details #Global #20DayTrends

This analysis includes all designated #SARSCoV2 sequences submitted to GISAID with sample collection dates on or after 01/12/2023
USA has submitted a lion's share of sequences with sample collection dates on or after 01/12/2023 ...followed by #Canada, #UnitedKingdom, #Austria, #Japan, #Denmark, #Germany, #France, #China, #Australia, #Italy
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
#SARSCoV2 lineages DS.1^^ (BN.1.3.1.1), XBB.1.5*, XBF, BN.1*, DN.1.1^^, XBB.6.1^^, XBB.1.9.1^^, CJ.1^^, CP.1.3^^, XBL^^, XBK^^ are in the zone of concern (red box) - Predicted to have high immune escape and tight ACE2 binding affinity!

DS.1* stands out!

^^ low sequence count
What to expect in the next few weeks?

#California, #NorthCarolina, #NewYork, #NewJersey and #Massachusetts have submitted a big share of sequences

XBB.1.5 stays strong at the top spot and is establishing a clear foot print outside NE USA!

USA Airport surveillance update #15DayTrends

125 sequences from 6 US States (#California, #NewYork, #Washington, #NewJersey, #Georgia and #Virginia)

#COVID19 #UglyPeak update

#SARSCoV2 Test Positivity Rate: 33.5% (slight very high and early signs of trending up again)

Source: @Walgreens Image
Treat this like an election exit poll - includes tests performed at Walgreens sites nationwide

1) We are still riding the #UglyPeak
2) Potentially many missed and unreported cases
3) Pandemic is far from over!
Walgreen's Variant proportions data (variants as of 01/23/2023) is consistent with #COVID19 Variant Dashboard #15DayTrends - Image

Sequence count by US State

Large share of sequences from outside NE States with specimen collection dates in the last 15 days.

The proportion of BQ.1*/BQ.1.1* >> XBB.1.5 outside NE states.

XBB.1.5 is expected to outcompete all other circulating lineages soon.
