"Surveillance indicators suggest that COVID-19 activity at a national level has increased or remained high during week 44.
"Positivity rates were highest in the 80+ year olds tested through both Pillar 1 (NHS and PHE testing) and in the 10 to 19 year olds tested through Pillar 2 (community testing)."
(positivity indicates whether enough testing is being done)
Levelling off in Pillar 2 cases. However, this is due to testing capacity issues &/or not enough people coming forward.
Positivity in Pillar 2 unacceptably high (not enough testing)
How old are people with these detected cases (Pillar 1 and Pillar 2)?
Where are the detected cases (Pillar 1 and 2)
Where are the outbreaks / incidents? Slightly fewer this week (may be half term effect reducing cases in educational settings)
Still many (though slightly fewer) outbreaks/incidents in care homes this week
"Significant excess all-cause mortality was observed in week 43 overall, by age group in the 75 to 84 year olds and 85+ year olds and subnationally in the North West and Yorkshire and Humber."
Where are people being hospitalized? On the left is hospitalizations; on the right, admissions to ICU/HDU. People appear to be disproportionately admitted to ICU/HDU in London

The updated SPI-M slides - a short thread on what's changed.
On 31 September, in a hastily arranged press conference, the Chief Scientific Adviser presented these two slides, showing projections for hospital admissions and deaths.
These were subsequently revised
The first slide shows a *projection* for hopsital admissions. On the left, the oringial slide, on the right, the amended slide.
These slides present a *range* of the projection (the shaded blue area), and a central projection (the dark blue line).
The upper level for the range of the projection has changed but *the central projection* (the dark blue line) *has not changed*
This is not as stringent a lockdown as before - children are still at school (which has benefits for the children), and people are less apprehensive than the first lockdown.
The lockdown was announced in advance, and we have seen people go to shops yesterday in great numbers to ensure they have the products they want.
And yesterday was seen by some as the last chance for a gathering.
Both these things will have increased transmission.
Due to the less stringent measures this time around, it will mean that it will take longer for the incidence of the virus to reduce. (We could have timed measures around the half term holiday, which would have meant that the measures were more effective).
A thread on the modelling and analysis used to suggest scenarios for what *could* happen if we do nothing. And commentary on this slide.
The slides that were presented in the Number 10 press conference on 31 October are here: gov.uk/government/pub…
Firstly, commentary on the modelling. Modelling for Covid-19 is performed by a number of academic groups around the country. They use different modelling techniques. Some of these models are used to come up with the R value.
Let's take a little review of where we are with UK Covid restrictions.
It wasn't meant to be like this.
A Thread.
With apologies to Nandos.
It wasn't meant to be like this. Remember the Alert Levels (the 'Nandos chart')? The whole idea of that was to set some sort of policy - a roadmap if you will - of how we get out of a national lockdown.
