While not downplaying our current careful situation, I think we've got a lot to be optimistic about in 2021, if we can think globally 🌍 & act appropriately 💉😷
On conspiracy theories:
"Unfortunately, conspiracy theories have become very dominant in the pandemic. I can understand: [they often] provide much simpler explanations. We scientists should learn from this, to make what we say more accessible and understandable."
2/5
On mutations:
"If many people have already been infected, it is an advantage for a virus [to evade] this immunity. A year ago that would not have been of any use to the virus. But now... we just have to be aware that the pandemic is not static. It is constantly changing."
3/5
On why continuing to reduce cases is important:
"It's a win-win scenario. In the worst case, variants [increase] cases - but we start with a lower case number - a better position. In the best case, the cases go down, the variants have no effect - & we can relax measures."
4/5
And on my reasons for cautious optimism as we move through 2021:

📅CoVariants.org is now updated with data up to the 18th Feb! 📅
Plus! A new mutation has been added 😉
And we've had another few neat feature tweaks thanks to some great contributors!
1/6
Enough recent data has come through to push the graphs to the next 2-week mark (they're plotted by sequences per 2-week period to help avoid weekly jitters), so the most recent data point is the 8th Feb now (covering the period two weeks after this).
2/6
Linking with our recent preprint on the S:Q677 variants, S:Q677 is now included on CoVariants!
We can particularly see 677 showing up clearly in the USA 'Per Country' graphs.
Tweets haven't been happening as times get busy, but CoVariants.org is now updated to data from 15 Feb! Focal builds are in the oven 🥖
This update also includes some neat new improvements - let's take a quick look!
1/4
Thanks to @jamesscottbrown, pages are now a little tidier, with the link icons placed after the links!
Thanks to a suggestion by @theosanderson the proportion of 'other' variants on the 'Per Country' page are now grey - easier to see and label!
2/4
@ivan_aksamentov has helped greatly improve the 'Per Variants' page! Tool-tip legends now show the lines so you can see the difference between solid & dashed!
And you can now select what kind or order you'd like the legend to show - frequency or country!
We found the same #SARSCoV2 mutation at position 677 in Spike has appeared at least 7 times in US-focused clusters in the past few months. What have we seen, & what does it mean?
Sparked by @macroliter & @DDomman independently spotting a rise in Q677P mutants in New Mexico & Louisiana, we teamed up & started investigating!
We noticed an increase in both Q677H and Q677P mutants around the world and within the USA, in particular since autumn 2020.
2/17
On a S:Q677-focused Nextstrain build, it quickly became apparent that there were multiple separate branches where Q677 mutants had arisen independently. We focused in on those in the USA.
It's #WomenInSTEM day today! 👩🏻💻👩🏾⚕️👩🏿🎓👩🏽🔬
I'm terrified of making lists of Twitter names as I know I'll leave someone off.
But I want to express how absolutely inspired I have been by the many brilliant women I've had the opportunity to work with this year & throughout my career!🎉
I absolutely remember how important it was (and is!) to be able to see myself in women who were in positions I aimed to achieve. Representation matters *so much.*
It helps to break down the expectations & stereotypes we often unknowingly internalise & realise what's possible!
Just 1 anecdote:
The first time I heard a brilliant women scientist whom I admired matter-of-factly state that she was looking forward both to the conference 🗒️ /and/ to shoe-shopping 👠 in the city it was in was *a revelation* for me. 🤯
Let's take a quick look at some snapshots of what we can see in the latest data.
1/15
Important note: the S:N501 build is now being more significantly impacted by downsampling.
I'm working on addressing this, but in the meantime, suggest looking at the S:E484 build for 501Y.V2 & 501Y.V3 & checking out the CoV Lineages report! cov-lineages.org/global_report.…
2/15
Israel now has over 200 sequences in 501Y.V1 (B.1.1.7). The latest additions indicate separate introductions (mostly from a month or two ago) and a large and still-growing local cluster.
As well as the major variants of concern, we can spot a couple of other clusters stemming from an 'old' #SARSCoV2 clade, 19B (originating in late 2019).
19A & 19B haven't been around much since early 2020, as they were overtaken by 20A, B & C (which carry D614G).
2/5
However, a few branches of 19B seem to be popping back up again recently.
In the UK, we can see a recent cluster that's acquired S:E484K (along with other mutations in S).
