My sister reports low mask use in her area of London (the elephant), plus a confusing bunch of people voluntarily wearing masks but not covering their noses. Nowt as queer as folk.

It's not completely insane. If you believe the coronavirus is spread by droplets, then your nose is fairly harmless as the exhaled air stream is pointed downwards, while air from your mouth is propelled forwards, so needs a mask. While we all know that it's spread by aerosols, there has been so much emphasis on droplets - especially the 1m/2m/6foot rule - that it's understandable that some people believe it.

I can pretty much guarantee nearly all "mouth maskers" have given no thought to the aerosol vs droplet issue.

It doesn't explain the confusing group of people who voluntarily wear a mask on the bus, but under their chin. I kind of get the not covering the nose thing. That group of people have always existed. Up until now I'd always assumed the the 'under the chin' group of people were just breaking the rules because they didn't want to wear a mask. But now they don't have to wear a mask and their are still wearing it under their chin anyway.

Good thread here about yesterday's anti-vax, anti-lockdown demo in Trafalgar Square citing some of the bollix the speakers said. f.cking terrifying.

I'd guess that some, if challenged would say that they were wearing a mask, and others just want to be close enough to wearing a mask that they can rapidly re-position it, making challenging them tiresome as you know that they'll just move it again soon - unlike someone who has been forced to go and get a mask.

just had a message to all clients from my vets, saying that they're keeping mask wearing and other covid protocols in place

but have had clients abusing their staff because of this - seriously? how can people be such utter a..eholes?

they're sticking to their guns though, and have 'withdrawn services' from certain clients

I'll be buying food and accessories from their branch much more in future

I think we have our first clear signal of a “Step 4” effect in today’s reported case data. While growth is flat in older age groups (>40s), and maybe even still falling in under-15s (a schools effect?), it’s picking back up in the young adult (15-40) group.

[...]

Looking –as usual- at the 20-24s, with no averaging, we can see a very clear reversal of the growth trend. That final datapoint on 27th July is incomplete so is very likely to go above the red line i.e. back into week-on-week growth, once the full data is filled in.

[...]

Why is this? The simplest explanation is that we’re seeing the impact of the first weekend after “Freedom Day”, with clubs / parties / festivals etc. leading to more infections. The timing fits, with Friday night’s infections being reported on a Tuesday specimen day.

[...]

There’s no clear differentiation in male & female case rates this time, but there is a bit of a split by region, with a stronger pick-up in growth in the Midlands (East and West), South East and South West, and weaker signals in London and the North West (more immunity??).

[...]

The important questions now are: how far does this pick-up in growth go? How long does it last? And does it spread into other age groups, or stay concentrated in the 15-30s? There’s no reason at all to panic, but we do need to keep a close eye on this.

? There's no uptick in cases. The data is inherently noisy, two or three days of data doesn't provide a signal. I can't trust any twitterer who spins lengthy narratives from tossing three tails in a row.

Alternatively are we sure there was even a downtick? How many days in a row was that?

Still you're right that we should wait a week or so to be sure which way it's going.
