Oooh! Thanks for that

. When I retired I promised Mrs KAJ that I'd leave my committees and wouldn't take on any consultancy work, but I'm not getting paid and she's interested in COVID, so I'll give it a whirl. My "everyday" Chromebook is too old to have the Linux option but I have a more modern "spare" (dodgy touchpad, but can probably use a mouse) so I'll give it a try with that.
Well I managed to install R and RStudio. For the benefit of others, my Chromebooks linux is Debian 10 Buster which gave dependency problems with the current RStudio. After quite a lot of time with Google the solution which worked for me was by "kevinushey RStudio Employee"
here.

That said, it's not helpful having all the different pillars mixed in together as they change at different rates and measure different things. Ideally we'd be able to get data just for Pillar 2 and hard numbers for positive, negative and void - I couldn't find that info on the ONS site, is it available anywhere?
The UK gov site (
coronavirus-staging.data.gov.uk ) does say "Number of confirmed positive, negative or void lab-based COVID-19 test results, by pillar" but the numbers do seem to be the total of "confirmed positive, negative or void", not the individual values.

Yes, exactly - I even downloaded the CSV to check. For each pillar they give you the total of "positive and negative and void" but not each value disaggregated, which is....less than helpful.
I think for these purposes we just have to assume that new cases = positive test, and that nothing systematic is varying in the proportion of non-positive results that are negative vs. void.

492 Covid deaths in the UK announced today. The death count follows the curve.

New case numbers here seem to want to stabilize at about 30,000 per day following the exponential increase which took off about a month ago; deaths per day have been at about 1% of new cases per day during this. (They were at 10% during the first-wave outbreak.)

Yes - I'm in a facebook discussion with people I know from the kids' primary school and one asked how I knew that the ONS excess deaths would continue to rise (for week 44 and 45) and I pointed out that wasn't even extrapolation.
I also got the Carl Henegen and Mike Yeadon videos too saying that Flu is a bigger problem
I guess they'll realise in a couple of weeks time.

The fit to the (exponential) curve is substantially better for deaths by date of death than deaths by date of publication. Even better for 7-day moving average. The doubling time is ~11 days for all three options.

Interestingly (to me!) the doubling time for cases is ~16 days (with cases by specimen date fitting better than by report date).

Ah well - It got through, so at least that's several who'll listen to those with more scepticism.

Two things I learned from today's news conference:
1. Sir Simon Stevens should be on more. He had way better slides than last Saturday's nerdfest and he talked like a normal person.
2. While looking
here for the correct spelling of "Sir Simon Stevens", I discovered that Donald Trump Jr has escaped and is now undercover as a BBC health correspondent.

I'm not liking this new variant that's popped up in the Danish mink farms

A bit more stewing of Covid sequences in animals was not what we needed at this point. One to watch, I think...hope it comes to nothing.

I must have missed all the "hilarious" jokes by right-wing comedians about those dirty Americans eating MinkDonalds and using mink for the incompetent development of bioweapons. I assume the PC police got to them first.

Wildlife trade bad. Intensive animal husbandry OTOH is apparently an unassailable component of civilization, and the pandemics it produces are a price worth paying for cheap meat and fur coats.

I must admit. I had no idea mink farms were even a thing until I read about the Covid outbreaks there.

A rapid coronavirus test at the heart of Boris Johnson’s mass-testing strategy missed more than 50% of positive cases in an Operation Moonshot pilot in Greater Manchester, the Guardian can reveal.
The 20-minute tests, on which the government has spent £323m for use with hospital and care home staff with no symptoms, identified only 46.7% of infections during a crucial trial in Manchester and Salford last month.

I’m guessing these are dowsing rods with the words “Bomb Deetectcor” Sharpied-out and replaced with a badly-scrawled “KOVAD”.

It's a
LAMP-based assay (isothermal PCR). My OH (reformed virologist) spent some time working on LAMP-based diagnostics for plant and animal diseases. Her general opinion of LAMP after that was that it is massively unreliable so I'm not surprised this didn't work.

Wrong. We saw exponential growth during the pandemic. But what we see now is linear growth. I’ll attach the picture again. It’s a straight line, linear.

Now of course I think mink farms are cruel and shouldn't be allowed BUT...
If they are culling 17 million mink to prevent any spread surely a hot wash with a bit of Persil / Ariel would make the fur safe to use??? And help put a dent in the carbon footprint associated with all that ethic fake fur?

Italy and France are a bit f.cked. Look at the acceleration from near-zero in the former and the sheer number of cases in the latter.

I've tried to extrapolate the exponential back to see if it coincides with the mid-September return to school, but it really kicked off at the end of October. (Whereas the bump you see before that is probably the end-of-August return from holidays which seems to have been kept under control during September.)
Based on the death or hospitalization rates we're probably picking up about 10 times more cases than during the first wave but yeah, hospitals are in trouble, and deaths are on course to be as bad as the first wave.
I consider it a big pile of f.cking b.llsh.t that we tried to go on with half-arsed restrictions until yesterday but then people here weren't really ready to accept a second preventative lockdown and are barely ready to accept it now.

"day 102" is June the 1st, by the way. October the 1st is 224. Sorry about that but plotting dates is a pain.

How would using the ECDC data instead of the one I get from Italy via a git help with the way LibreOffice charts deal with dates?
