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).

11/14

https://t.co/fOPgetG9S8
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).

4/10


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).

So today, I am going to quickly talk about 4 or 5 countries where you can get residence visas.

Why residence visas?

For starters, they are cheaper, FAR CHEAPER than passports, and offer almost all the benefits, not not, but a large swathe of them.

Second, residencies can be...

a pathway to citizenship.

In one or two of the countries I will talk about tonight, if you renew your residencies long enough, and fulfill all requirements, according to their law, which differs from country to country, you become eligible to apply for full citizenship.

So...

you can see why they are good enough?

Cool. Alright, let's begin.

The first country is

1. Barbados

Yes, @Rihanna's country.

The first thing I love about it is it's fully black, majority descendants of ex-slaves of Igbo extraction.

That's why they refer to their country...

Barbados last year officially launched its 12-month Barbados Welcome Stamp, a new visa that allows remote workers to live and work from the Caribbean country for up to a year.

Applicants must electronically submit documents, such as a copy of their international passport and...

From today, we will memorize the names of 27 Nakshatras in Vedic Jyotish to never forget in life.

I will write 4 names. Repeat them in SAME sequence twice in morning, noon, evening. Each day, revise new names + recall all previously learnt names.

Pls RT if you are in.

2

Today's Nakshatras are:-

1. Ashwini - अश्विनी

2. Bharani - भरणी

3. Krittika - कृत्तिका

4. Rohini - रोहिणी

Ashwini - अश्विनी is the FIRST Nakshatra.

Repeat these names TWICE now, tomorrow morning, noon and evening. Like this tweet if you have revised 8 times as told.

3

Today's Nakshatras are:-

5. Mrigashira - मृगशिरा

6. Ardra - आर्द्रा

7. Punarvasu - पुनर्वसु

8. Pushya - पुष्य

First recall previously learnt Nakshatras twice. Then recite these TWICE now, tomorrow morning, noon & evening in SAME order. Like this tweet only after doing so.

4

Today's Nakshatras are:-

9. Ashlesha - अश्लेषा

10. Magha - मघा

11. Purvaphalguni - पूर्वाफाल्गुनी

12. Uttaraphalguni - उत्तराफाल्गुनी

Purva means that comes before (P se Purva, P se pehele), and Uttara comes later.

Read next tweet too.

5

Purva, Uttara prefixes come in other Nakshatras too. Purva= pehele wala. Remember.

First recall previously learnt 8 Nakshatras twice. Then recite those in Tweet #4 TWICE now, tomorrow morning, noon & evening in SAME order. Like this tweet if you have read Tweets #4 & 5, both.
