In the 501Y.V1 (B.1.1.7) variant, here are a few of the non-UK countries with new sequences in this variant, including Denmark, Italy, Spain, France, Portugal, Norway, Germany, the USA, South Kora, & Switzerland, & the UAE, Austria, & Czech Republic for the 1st time

2/18
Denmark has 52 new samples (some yellow), showing both separate introductions and further spread of existing local clusters.

3/18
Spain has 62 new sequences (orange & yellow). Many of these are separate introductions, and a few new sequences form distinct clusters. Some new sequences also cluster closely with older sequences (green).

4/18
France has 72 new sequences (orange & yellow). These show both separate introductions and clustering with older sequences.

5/18
Portugal has 30 new sequences (orange), most of which are separate introductions, but some do connect with previous sequences.

Norway has 10 new sequences (yellow). Most of these seem to be separate introductions.

6/18
There are 10 new sequences from South Korea (yellow). These are separate introductions, but some of the new seqs cluster, which could indicate local transmission or a common exposure source.

7/18
Germany has 9 new sequences (orange & yellow), which indicate separate introductions.

8/18
The USA has 123 new sequences (orange & yellow). Many of these do cluster with older sequences and seem to indicate ongoing local transmission.

9/18
Switzerland has 30 new sequences (yellow & orange), many of which indicate separate introductions.

10/18
India has 3 new sequences (yellow). These connect to older sequences, which may indicate local transmission or a common exposure source.

11/18
United Arab Emirates has 21 sequences for the first time. Many show independent introductions, but some form a large cluster that is likely local transmission.

12/18
The Czech Republic has 10 sequences for the 1st time and Austria has 41 sequences for the 1st time.

All the Czech & many of the Austrian seqs fall in 1 cluster each, likely indicating local transmission. These clusters are near each other & connected to Slovakian seqs.

13/18
In 501Y.V2, there are new sequences from Germany, Denmark, Spain, the United Arab Emirates, and Belgium.

14/18
Germany has 4 new sequences (yellow & orange). Some indicate a new introduction, others link to an older sequence.

15/18
United Arab Emirates has 5 sequences for the first time, showing multiple introductions.

16/18
Belgium has 6 sequences for the first time, showing multiple introductions.

Denmark and Spain also have sequences for the first time.

17/18
As always, the country plot table is now updated - as usual, be careful interpreting, as sequencing is often still biased toward "S-drop-out" & S:N501 samples, meaning frequencies are not representative.

🎉Happy New Year!🎉

To kick off 2021, here's an update on:
- S:N501 variants (501Y.V1/V2) with data from 31 Dec 2020
- 69/70del variants
- 20A.EU1 variant (most prevalent variant in Europe)

(Here are some fireworks that look a bit like phylogenies! 🎆)

1/23


The latest sequences from 31 Dec show new sequences in the S:N501Y.V1 variant (originating from SE England) from Netherlands, Denmark, Australia, Italy, Canada, the USA, Germany, Switzerland, & India.

Canada, Germany, & Switzerland all have sequences that fall in 501Y.V1 for the first time, scattered across the tree.

3/23


The USA also has its first 2 sequences that fall in 501Y.V1, from Colorado & California. India also had its first 3 sequences, also from different regions.

In both cases, the sequences are not connected, indicating separate introductions.

4/23


In countries with previous sequences:

6 new sequences from Netherlands, in orange/yellow (green are older).
1 is clearly separate - zooming in (& in divergence view, coloured by country) it is harder to determine the relationship between the others.

5/23
Each day brings new challenges, but here's an update to the dedicated S.N501 build, using data from 6 Jan 2021 to keep you going.

There are 42 new non-UK sequences in 501Y.V1 (B.1.1.7) & 7 new non-South-African sequences in 501Y.V2.

There are 42 new non-UK sequences in 501Y.V1 from the Netherlands, Italy, Hong Kong, Finland, Sweden, Germany, USA, Switzerland, Brazil, and the first sequence from 501Y.V1 in Oman.

https://t.co/XA8VR8HiEq

2/14


Oman has their first sequence which falls into 501Y.V1:

3/14


Finland has 12 new sequences (orange), which mostly represent separate introductions. Zooming in (divergence view), we can see 3 of the new sequences are identical (red), which may indicate the cases are connected.

4/14


Sweden has 8 new sequences (orange), which indicate separate introductions.

Ivor Cummins has been wrong (or lying) almost entirely throughout this pandemic and got paid handsomly for it.

He has been wrong (or lying) so often that it will be nearly impossible for me to track every grift, lie, deceit, manipulation he has pulled. I will use...


... other sources who have been trying to shine on light on this grifter (as I have tried to do, time and again:

19 to 80 is an over 300% difference.
