Let's not lose sight of what's happening.

We may not be able to rely on case data. But here's the latest PHE map of cases. Not now restricted to the north east and the north west - look at London

So if we can't rely on cases, we have to use other metrics. Image
Here is a graph of admissions to hospital in England.

478 people were admitted today. And the trend is upwards. Image
What happens if you deteriorate is that you end up in ICU or a High Dependency Unit.

So what's happening there? These are increasing too. Image
And, sadly, deaths (note that there is a delay in reporting deaths, and that only deaths within 28 days of a test are shown here) Image
Remember that deaths from case numbers reported now are inevitable. It takes just under a week to present symptoms from catching the disease, and a week or so before admission to hospital, and a few weeks after that until sadly some people die.
We know more deaths are coming. Government policy can influence how many.

The question we need to be asking is:

What is the Government's reasonable worst case scenario estimate for deaths?

And, if the Government cannot provide an answer, why not?

I thought I would share with you the PHE work on where cases are on the watchlist.

For each:

A map showing how cases per 100,000 last week and this week.

A chart showing positivity. High positivity = not enough testing.

Here's the national picture. Image
For context, New York closing schools at 3%. However, positivity in New York may be measured slightly differently.

Here is a case study - Liverpool vs New York

We may be systematically underestimating R by excluding students in halls of residence. A Thread
We know that data on the Government Coronavirus dashboard is unreliable (see this thread)
We also know that we are not doing enough testing as the positivity rate is so high (7% overall for Pillar 2 tests and up to 15% in some areas such as Liverpool) (see this thread)

Nearly 23,000 Covid-19 cases were reported today. This is due to a delay.

Analysis thread.
Public Health England have released a statement. It is here: gov.uk/government/new…

First, note that the Department of Health and Social care is the data controller for Pillar 2 tests. It passes these data to Public Health England, and DHSC are responsible for the data.
The statement says:
"we have identified that 15,841 cases between 25 September and 2 October were not included in the reported daily COVID-19 cases"
