Correcting an important misconception (this is my chart, but misleading commentary):
•There were thousands more cases among young men than women after ⚽️ matches, showing impact of Euros on transmission
•But not due to attending matches. It was indoor gatherings to watch games
Of course, that still means the transmission bump was driven by the football, but match attendance is only a small part of the cause. The bulk is mixing in pubs, bars, homes etc, plus some from crowded transport to and from those indoor gatherings (and matches).
Thoughts on implications:
• I would guess these watch parties happen at a much larger scale for England games at major tournaments than they do for typical club games, but we've not had pubs fully open during the season yet so that will be worth monitoring.
• What this data also shows is that behaviour (more indoor mixing) really matters. Good news is we now have millions more fully vaxxed in the UK than during Euros, but as reopening + worsening weather send more people indoors, don't be surprised to see an impact on the numbers.
Here's our full story with @clivecookson on how to make sense of the falling case numbers in England, what they might mean for hospital admissions this week, and how we might expect the reopening to show up in case data on.ft.com/2UIKMWM

There’s a wild story about the women’s gymnastics at the Sydney Olympics in 2000, which I think is very relevant to what we’re hearing about Simone Biles, and the wider point of how the top level of elite sport is just as much mental as it is physical.
In the women’s all-round final in 2000, the organisers set the vault at the wrong height. Two inches too low. This was a pretty huge deal.

For competitors who have done thousands, maybe tens of thousands of vaults at a specific height, a two inch difference is night and day.
In the first round, 17 of 36 finalists fumbled the vault

One landed on her back. Clear gold-medal favourite, Russia’s Svetlana Khorkina (comfortably won qualifying) landed on her knees.

Total chaos, and nobody knew why. Athletes second-guessing themselves.

I feel like I've seen this before somewhere 🧐🤔
Lol that they couldn't even be bothered to change a single one of the numbers.

NEW: people worry when they hear "40% of hospitalisations are fully vaxxed", but this chart shows that's actually good news.

The more people you vaccinate, the higher their share of hospitalisations, but the *total* number in hospital is a fraction of what it would otherwise be
If fewer people are fully vaccinated, a smaller share of hospitalisations will be fully-vaxxed too, but this is not a good thing:

Overall there will be a lot more people in hospital because far more of the population is unprotected.
In other words: if you want to know whether the vaccination program is working, don't focus on whether the fully vaxxed make up 40% or 12% of hospitalisations.

Focus on whether the hospitalisation rate is 270 per million or 684 per million.

NEW: probably the most important Covid chart I’ve made

As Delta goes global, it’s a tale of two pandemics, as the heavily-vaccinated Western world talks of reopening while deaths across Africa and Asia soar to record highs

My story with @davidpilling ft.com/content/fa4f24… Image
Here’s another version, zooming in on the last few months.

In two well-vaccinated European countries, weeks of surging cases are reflected by only a sliver of deaths.

In eight countries where very few are vaccinated, surging cases are mirrored in surging deaths as before. Image
A grim gulf is opening up between the wealthy, mostly vaccinated world and the poorer, mostly-unprotected.

In the UK, vaccines have reduced the case-fatality rate roughly 12-fold, from ~2% to 0.16%

In Namibia, Tunisia, Malaysia and Indonesia, death rates have never been higher.

A huge thanks to everyone at the FT who made this possible. Both the rest of the brilliant data/visuals team, and the editors and reporters across the rest of the FT who really *get* the power of data journalism more than any other newsroom I've encountered.
We're not in the business of making charts to dress-up stories. We make charts that *are* the stories.

Another excellent chart idea from @BristOliver

Just as in previous waves, cases today are an excellent guide to where hospital admissions will be 10 days into the future.

But there is a difference this time around, and here come two charts to illustrate it...
Here’s the same data, but adding the autumn/winter wave, and expressing everything as % of January peak

Spot the difference between waves:

Admissions track cases ~perfectly both times, but this time red admissions line is lower: a smaller share of cases require hospital (💉💪)
And here’s the same data using another @BristOliver concept: admissions as share of cases 10 days earlier.

Today admissions are ~4% of lagged cases. At this point in the autumn wave, they were ~8%.
