Merry Christmas! 🎄 The latest focal S:N501 build is now up.

Zooming in on 20B/501Y.V1 (SE England variant), we can see new sequences in Europe from the Netherlands.

Zooming in on this further, and switching to divergence view (showing mutations rather than time), we can see they share 1 unique mutation & then have 1 unique mutation each, suggesting 1 introduction, possibly from the UK, & onward transmission.

We can take a similar look at the Danish sequences. They too, share one unique mutation, & some further unique mutations, suggesting a single introduction & onward transmission.

Finally, we can also see the new sequence from Singapore.

Remember: though all these sequences nest closely in UK diversity, the UK generates data much more than other countries, so there could be unsampled links which might fit between samples.
