It's the unequal distribution that's the thing.

The area I'm in was high from August to October, & our team's been at ~50% capacity throughout that, which isn't very functional. With each wave, we have a small % who struggle to recover, too - have 2 who were ill in August & still not ok.

Thanks for your patience, Michiel! It's taken a while, but we've got there...

And there is a very clear rebound along much of the south coast, particularly in West Sussex, but also in Portsmouth, Dorset, and Devon.

London has looked to be behind this wave throughout, and what reporting there is indicates a sting in the tail of the wave.

I suspect outbreaks will continue piecemeal for some time across the city.

Levels are still high in Worcestershire and Gloucestershire.

But they have declined in Dudley, as across the Midlands, and I hope Worcs. and Gloucs. are to follow.

Barnsley and Rotherham are struggling, too.

Hull is the outlier, in black on the map, but something has gone very wonky with their reporting - I can't tell if this is indicative.

The East Riding's reporting is not good either, but it's enough to suspect a swell.

The average for Scotland is declining in most areas, as it is in England.

But that's not the case everywhere.

Teesside and Cumbria look to be having another - though smaller - rebound.

The highest rates in Scotland at the moment are in Highland and Na h-Eileanan Siar, with Angus, East Lothian and Midlothian a little lower.

The testing & reporting is solid.

Worth remembering that Scotland also has wastewater monitoring by LA.

We're grateful to Public Health Scotland's data analytics team, who looked at the map, understood its value, and willingly worked with us.

They went above and beyond in producing a bespoke dataset just for the map.

If it's of value to you, please do thank @publichealthscot.bsky.social

You'll see we've also included the Scotland total average.

Unlike England, this is not adjusted for non-reporting - my experience with the Scottish data tells me it won't necessary (I'll keep an eye on it).

The Scottish data is also more recent, running up to 4 days ago, i.e. last Sunday.

When you click on a Scottish local area, there is no trendline, as the data is delivered as a weekly total.

You can check the underlying data in the same way as England: by clicking on the name of the area in the pop-up bubble.

There's a little more to do until we have Scotland on the map too.

It should be ready for next week's release.

Meanwhile, here's the PCR positivity percentage for each Scottish LA as of four days ago.

Still some very high & climbing levels in South Yorkshire: Doncaster and Barnsley particularly.

Sheffield & Rotherham still look volatile.

Further north, Bradford & North Yorkshire appear to be rebounding upwards.

Levels have calmed in the Midlands, but not yet in Shropshire, nor in Dudley or Sandwell.

Leicester and Wolverhampton are also rebounding, but from much lower levels.

London too looked like it was behind the curve in this wave, and anecdotal reports have suggested a recent increase.

Lots of poor or non-reporting in London but what there is backs that up.

The Isle of Wight sorted out its testing & reporting issues recently.

It seems to be behind the curve: still bouncing up and down around 20%.

A lot of areas are dropping quite fast, but you can still see plenty of purple, red, and orange on the map.

I'm going to focus on those areas seeing a rebound.

It is, yes: we've been discussing that a lot. Scotland had a bigger peak at the end of August (per wastewater, admissions, other surveillance) so... a little bit of residual short-term immunity helping there? That's my best guess, anyway.
