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.

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.

5/14
Italy has 6 new sequences (orange), which indicate additional independent introductions.

6/14
Netherlands has 4 new sequences (orange), indicating 1 clear additional introduction. The other new sequences cluster with older sequences, possibly indicating local transmission.

7/14
Switzerland has 3 new sequences (orange). 1 is clearly a separate introduction.
Zooming (divergence view), we can see 2 of the new sequences differ by 1 mutation, & connect to a UK sequence. More info would be needed to conclusively determine if this is local transmission.

8/14
Brazil has 2 new sequences, 1 (marked) shows a new introduction. The other connects to a previous sequence. Zooming in (divergence view) we can see this more clearly - they are identical, and this may indicate local transmission.

9/14
Hong Kong, Germany and the USA (from New York), each have 1 new sequence (orange), indicating additional introductions.

10/14
Moving on to 501Y.V2, there are 7 new non-South-African sequences in 501Y.V2, from the United Kingdom (6) and Sweden (1).

Sweden has a sequence in 501Y.V2 for the first time.

12/14
UK has 6 new sequences in 501Y.V2 (orange), including 1 from Scotland. Most indicate separate introductions, but 1 new seq links to the older 1 (blue). Zooming (divergence view), they are separated by 1 mutation. This could indicate local transmission or the same exposure.

13/14
As always, the graph of variants per country is updated (remember: as people are preferentially sequencing S:N501 samples, the proportions shown are not accurate outside of UK & Denmark!)

Additionally, the 'reduced UK' S:N501 build is updated!

Lots of tweets about this today!
Let's see what we can see in the focal S:E484 build!

Phylogenetics (what I do - making 'family trees' from virus genetics) can be very informative to see how different variants are spreading, and how cases

There are two variants circulating predominantly in Brazil:
- 20B/S.484K seems to be older & more widespread. It has (among others) a mutation at position 484
- 20J/501Y.V3 is smaller & detected recently. It has mutations at 501 *and* 484.

The variant predominantly in the UK (501Y.V1 / B.1.1.7) and the variant predominantly in South Africa (501Y.V2) also both have 501. 501Y.V2 *also* has the 484K mutation.

Why are there concerns about these mutations? You can read more at https://t.co/wVE7ubYBoy!

The view below is from an analysis focusing on sequences with a mutation at 484. It shows all the samples in the 2 variants (20B/S.484K & 20J/501Y.V3) & how they're related. More closely related = closer together (very, very roughly).

We can colour these samples by region to see where they're from. As we expect - most are in Brazil! A few are in Argentina (also red).

I hate when I learn something new (to me) & stunning about the Jeff Epstein network (h/t MoodyKnowsNada.)

Where to begin?

So our new Secretary of State Anthony Blinken's stepfather, Samuel Pisar, was "longtime lawyer and confidant of...Robert Maxwell," Ghislaine Maxwell's Dad.


"Pisar was one of the last people to speak to Maxwell, by phone, probably an hour before the chairman of Mirror Group Newspapers fell off his luxury yacht the Lady Ghislaine on 5 November, 1991."

OK, so that's just a coincidence. Moving on, Anthony Blinken "attended the prestigious Dalton School in New York City"...wait, what? https://t.co/DnE6AvHmJg

Oh that's right.

The dad of the U.S. Attorney General under both George W. Bush & Donald Trump, William Barr, was headmaster of the Dalton School.

Donald Barr was also quite a


I'm not going to even mention that Blinken's stepdad Sam Pisar's name was in Epstein's "black book."

Lots of names in that book. I mean, for example, Cuomo, Trump, Clinton, Prince Andrew, Bill Cosby, Woody Allen - all in that book, and their reputations are spotless.
