🎉CoVariants.org Update!🎉

22D (BA.2.75) is now available on CoVariants! It's visible as part of Per Country & Per Variant plots, on the shared mutation page - and of course, has a page of its own!

This is in line with the recent addition of 22D (BA.2.75) as a @nextstrain clade - read more on that below! 👇🏻

2/8

On the 22D page, you can read about some initial 22D / BA.2.75 work on things like immune-evasion, see a list of defining mutations, a plot of the variant growth, link to Aquaria protein viz, & see a list of other mutations present in the variant.

3/8

covariants.org/variants/22D.O…
There's also a link to the 22D / BA.2.75 @nextstrain focal build: nextstrain.org/groups/neherla…

Here, we can zoom in on the clade & get a closer look at how 22D sequences are distributed around the world, & their diversity.

4/8
On the Per Country page, 22D / BA.2.75 is currently only readily visible in India, where it likely originated & is most common, as well as a little in Japan. Over the next few weeks, it'll be possible to see if it grows in other countries.

Finally, on the Shared Mutations page (very hard to capture in a picture now, with the Omicrons!), you can see how 22D's / BA.2.75's Spike mutations compare to other VoC, including its Omicron siblings.

6/8

covariants.org/shared-mutatio…
More information on 22D / BA.2.75 will become available in due course.
As always, CoVariants.org is open-source & we welcome your PRs & suggestions to add more studies & information to variant pages! (Or any error-catching!)

7/8
As before, I've created a file for 22D / BA.2.75 mapping all defining mutations (relative to ancestral), including nuc->AA. This is available on CoV github!

Huge 🙏🏻 to all who helped check it! (Esp @DoktorYak & Anna N!) (Further feedback welcome!)

📯CoVariants.org Update📯

As I mentioned yesterday, from today we switch the Per Variants page to 2-week intervals without smoothing & fixed the "New Year bug" - making interpretation clearer & cleaner! 🎉

covariants.org/per-variant

1/7
HUGE thanks to @MoiraZuber & @ivan_aksamentov for their work on this! 🙏🏻

Previously, Per Country was by 2-weeks (unsmoothed) & Per Variant was 1-week (smoothed) - this made reconciling numbers confusing & unintuitive. The change makes all of that easier!

2/7
As part of this, you'll notice the graphs look a little more jumpy & angular 📐. That's what happens when smoothing turns off!
But, it more closely represents the real data - I think this is a worthy trade-off!

So far, #monkeypox seems generally mild (if sometimes very painful & physically scarring) - but is that enough not to worry?
I still think we need to consider our response carefully.

If it continues to be hard to contain, what are the medical *and* social risks?

1/14
At the moment, the #monkeypox outbreak impacts some parts of our world & society more than others - this is always dangerous as it makes dismissal easier. It's not threatening 'most of us' - at least not right now.



2/14
But if #monkeypox becomes widely endemic in MSM (men who have sex with men) populations, what might this mean?

1st, wider spread == more chance of spillover into other groups. Vulnerable, elderly, children - where outcomes may be different/worse.

🗒️CoVariants.org announcement🗒️
Currently on the Per Variants page, we use 1-week counts + smoothing. We're hoping to move away from this in the near future, & change to 2-week unsmoothed (same as we do for Per Country) for consistency.

1/2

covariants.org/per-variant
If you regularly use the Per Variant data & are concerned about any impacts from this change, please feel free to reach out on our Github Discussions page!

2/2

github.com/hodcroftlab/co…
As an update, this'll probably get merged in tomorrow morning (CET), so please do shout soon! File format will *not* change, but the interpretation will change slightly - and be closer to the raw numbers (thanks to getting rid of smoothing).

The speed at which BA.4/5 has dominated in Europe & caused rising cases is remarkable - but it isn't surprising at this point.
Summer waves are entirely possible, & scientists have been watching BA.4/5 for quite a while.
CoVariants.org/cases

The good news is that vaccines/previous infection still seems to provide good protection against serious outcomes (hospitalization, death) from BA.4/5

But, they have (yet again) increased immune evasion, meaning reinfection very possible, with mild-moderate disease course.
However, the rise in cases is being reflected, in many places, in a rise in hospitalizations. Mostly that's not causing too much strain, but it's worth monitoring.

The disruption is also being felt: people are out sick, causing some staff shortages.

Reminder that the *entire* point of Greek letter is precisely *because* anyone _can_ name a variant. That's how we end up with potentially inaccurate & discriminatory names.

If we/@WHO don't provide useful names for use, alternative names will start to appear.
#CentaurusStrain
We got lucky in a way with the 'first level' BA's (BA.1-BA.5) because they're simple enough for everyone to use & repeat.
But Pango lineages by nature can sometimes be more unwieldy: like BA.2.75 (which isn't even so bad). People start using shorthand!
Yes, we can ask people *not* to make up their own names.
But all we can do is ask.

If we don't address *why* people are coming up with alternative names - because they need an easier, recognisable handle - we run the risk they'll do it anyway. 💁🏻‍♀️

At #MCIDdynamics/#HumanViruses conference:
- Everyone tested on arrival
- All masked (except speakers while speaking) in sessions
- All breaks/lunch/posters outside
- Sewage monitoring in the housing

The most comfortable I've been at a conference recently. Organizers take note!
Doing things outside is much easier in San Diego than, say Texas 🥵 (where I am now) or many places in Europe 🌧️.
But requesting tests, masking, & ventilation are things that can be done anywhere. With cases rising in many places, we deserve to make conferences safer for all.
In particular, poster sessions - historically crowded, hot, & full of people drinking & talking loudly - are worth a rethink. Can we move them outside? To a much, much larger room? Open all doors/windows? Space them out? Encourage masking?
Worth considering creative solutions!
