Public Health England have published their latest (week 41) COVID surveillance report. However, this is in a new format called the 'influenza and COVID-19 surveillance report'. It is not clear whether a separate COVID report will be published

assets.publishing.service.gov.uk/government/upl…
This report does not appear to contain a watchlist of local authorities. Previous weeks have contained a watchlist of local authorities published jointly by PHE / Joint Biosecurity Centre / NHS Test and Trace.

See this for last week's
This is the chart for positivity. Increasing. Change of methodology this week - a good thing as a more conventional calculation.

'Positivity is calculated as the number of individuals testing positive during the week divided by the number of individuals tested during the week.'
Age groups of people testing positive
Proportion of age groups testing positive. Significant increases in 10-29 year-olds
Pillar 2 (community testing) positivity increasing significantly. Greater than 5% in Pillar 2 (indicating not enough testing being performed) (WHO guidance)
Pillar 2 (community testing) positivity broken down by age cohorts. Positivity of >10% for 10-19 year olds and 20-29 year olds. This indicates that not enough testing is being performed particularly in these age groups. Cases in these age groups particularly under-reported.
Covid case rates broken down by region. North East, North West, Yorkshire & Humber high.

East Midlands rising fast too (dark green line)
Covid cases map for the UK. Doesn't look as scary as last week - last week darkest red was for greater than 45 cases per 100,000.

It's now greater than 335 cases per 100,000.

If this was using the same colour scheme as last week, *everything yellow or above would be dark red*.
So, this week, the *whole of London* would be dark red if using the same scale as last week.

Here's last week's map for comparison. Things have got worse since then.

Deaths increasing
It is not clear whether the (only) Covid surveillance report will be published tomorrow. If so, I will produce another thread, which I expect will include hospitalisation location data and maps of cases in local authorities.
Correction. Most of London - the yellow London boroughs here (and potentially some of the green London boroughs)
* part of the UK :)
A couple of clarifications/corrections
- This is a map not of the UK, but of England 🙂 (data from Public Health England)
- The areas that would formerly be dark red are 27 of the 32 London boroughs: all London boroughs except for: Bexley, Bromley, Greenwich, Merton, and Sutton
And thank you to @rob_aldridge and @junipertwo for pointing me in the right direction: the Covid-specific report will no longer be published.

The watchlist and local authority maps have been published on Fridays, and I will look out for them tomorrow.

Although the watchlist of local authorities has not yet been published, you can make a rough estimate - here are the upper tier local authorities (these are the equivalent of county councils) and include unitary authorities such as Leicester.

105 out of 149, or over two-thirds
Only *three* of these 149 upper tier local authorities are below a threshold of 20 cases per 100,000

"above 20 per 100,000 are of particular concern when [the Government] decides whether to update the [self-isolation for travellers to the UK] list."

Here's a slide summarizing the colour scheme change

Here is my latest heatmap showing how cases are travelling through the age groups.

It is very concerning. Image
"The first thing to note is the more-than-doubling in the rate of Covid cases in 10-19 year olds. Many of these will be university students, but it's not clear how many of these are schoolchildren.
“Studies in Spain, France, and the US have all shown that although the second wave may start in young people, it will inevitably move to older people.

“The remarkable thing about this disease is that the death rate increases massively with age.

Commentary on the Slide Pack shown to MPs

'COVID-19 TaskForce: Data briefing 8 October 2020'

Here it is:

h/t @robpowellnews and @Smyth_Chris
Slide 1
Comment: The ONS survey does not include students in halls of residence so will underestimate due to outbreaks in halls of residence

But, yes, everything points to the epidemic not being under control

See: Image
Slide 2

Shows cases above 50 per 100,000. This is good. However, note several colour shades above this - not just the dark purple (and why no scale?) Image

Here endeth the National COVID-19 surveillance reports series.

gov.uk/government/pub… Image
These have been replaced with the National flu and COVID-19 surveillance reports. So, that's good.

And I'll be providing weekly updates on these.

But - a few things.
The new reports don't show hospitalizations by NHS trust. These were useful for showing e.g. the 5th highest hopsital trust with admissions per 100,000 population was in London, not the north of England

Test Trace and Isolate isn't working.

Specifically
- Testing isn't working
- Tracing isn't working
- Isolating isn't working
SAGE minutes of 1 May (Meeting 32) stated that 'at least 80% of contacts of an index case would need to be identified for a system to be effective'

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

Positivity calculations (please ignore this everyone, trying to work something out)

@theosanderson @ADMBriggs @dan_grey (please add in anyone interested)
We are trying to reconcile the data from this chart

Let's look at week 36, as that's what @theosanderson used in his FOI request
