1a. ONS incidence

The headline is that during the most recent week (18 to 24 September) there were around 8,400 new infections per day not including those living in institutional settings, *down* from 9,600 previous week.

Still not rising in the elderly

1b. Other incidence

We also had the Imperial "REACT1" interim incidence report this week which also pointed to a slowdown, and the KCL Zoe app (tracking symptomatic cases) points in the same direction

2. Care home outbreaks

Number of outbreaks down significantly in past fortnight, but still account for a significant % of institutional outbreaks (dwarfing hospitality).

3. Hospitals

3a Hospital admissions and deaths

Covid deaths from NHS England stats: england.nhs.uk/statistics/sta…

Covid admissions: rising linearly (*not* exponentially), likely flattening
coronavirus.data.gov.uk/healthcare?are… ImageImageImageImage
3b ICU admissions and Emergency Dept admissions

Extraordinary difference of ICU admission rates in different areas of the country, but nowhere remotely close to levels in spring.

Emergency admissions, again, levelling off.

Source: surveillance report ImageImageImage
4. Covid triage

Online / phone 111 covid triage starting to return to normal after the back-to-school/college jump, but (critically) the pattern in vulnerable >70s shows the same pattern as incidence: higher levels than summer, but levelling off

digital.nhs.uk/dashboards/nhs… ImageImageImage
5. Cases

5a. Pillars 1&2 - last couple of weeks & last month (2nd wave) & full curve (bear in mind the left-hand side was heavily rationed for testing, the right-hand side *far* less so: the 'two waves' are not comparable).

Again, levelling off.

5b. Breakdown of pillar 1 (clinical need / NHS) and pillar 2 (community swab) cases and % positive. Again, the left-hand side was heavily rationed for testing, the right-hand side *far* less so.

6 Contact tracing

400k contacts now reached; assuming (per Smith et al paper) 10% have isolated as instructed, at a cost of £12bn that is £240k per isolation. Value?

Mostly our own housemates and guests, who we could tell anyway

7 The Vallance-tracker

I'm going to drop this from future updates as it was a pointless and embarrassing thing for our CSO to have put in front of the media, and now looks snarky.

But note that the red line forecast (or whatever) is a mile away from blue line trend. Image
8 Mortality

Taking rolling last-12-months all-cause deaths, 2020 now doesn't look much more of an outlier above trend than 2019 was under trend.

Mortality has been at baseline since June.

9 Miscellaneous

9a Europe

Euromomo show deaths at baseline in all age-groups across Europe, Spain is the only country with above-average mortality ImageImage
9b Spain

Cases (dark green) and deaths (red) appear to have turned the corner; both are slowing. Poor Madrid looks to have had both a 2nd and 3rd wave.

Hospitalisations down 4 days on the trot, never growing exponentially.

mscbs.gob.es/profesionales/… ImageImageImageImage
9c France

Covid hospitalisations seem to have turned the corner about a week ago

9d ICNARC

Updated ICU report published by ICNARC on the cohort of people being admitted to ICU during the 2nd wave, and outcomes *so far*

icnarc.org/DataServices/A…
9e Papers

If you aren't covid-ed out, here's a couple of interesting old papers.

On the seasonality and mystery of flu, and why the best way to protect the vulnerable might be *not* to protect the healthy

This is Toby Young (@toadmeister)'s response to my piece in the @spectator, which he very fairly follows by a frontline account from an in-house senior doctor in London.

spectator.co.uk/article/lockdo…

I thought I'd respond briefly to the response: short thread 1/n
I am still a lockdown sceptic, and Toby sets out very well the principled objections to lockdown that I still believe too. 2/n
I still think the 1st lockdown went on too long, with harms likely to have outweighed the benefits. TikTok punting videos while people missed basic healthcare is revolting.

I don't think the 2nd lockdown was well justified: the arguments that convince me now didn't then. 3/n

1. Incidence

ONS: Incidence now up to 35k per day, 0.9% overall; huge variance regionally and by age group, with young getting infected *much* faster than old (good news), and this is backed up by Zoe (KCL/CSS) data: ()

ons.gov.uk/peoplepopulati…
2. Care home outbreaks / admissions

Care home outbreaks flat; still 3% of outbreaks. But admissions from care homes rising (so size of each outbreak bigger?)

*If* our interventions work, why are admissions from care homes growing at the same pace as elsewhere? 🤔

My experience of contact tracing.
---
My daughter was sent home from school to isolate Tuesday morning, following a positive test by her teacher (who had been isolating since Friday).

She rapidly developed (moderate) fever and kept falling asleep (fine now), so was tested /1
This was 2.30pm Tuesday.

Result came through 10pm Thursday; within half an hour we had phoned all contacts (piano teacher, school, houseguests, other direct contacts).

Contact tracers phoned us 17 hours later (Friday afternoon); we gave them all the same information. /2
I asked what the point of contacting people we had already contacted; they confessed "basically... not much".

Since then they have repeatedly been contacting us (in isolation) by phone and text to confirm our details, even though I've told them we're isolating. /3

1. Incidence

ONS shows continued increase in incidence as the seasons change, driven by areas of the country subject to enhanced lockdown restrictions.

Great news: clear divergence between incidence in the vulnerable >70 versus younger age groups.

ons.gov.uk/peoplepopulati…
(Caution due on the NE/Yorks piece of that chart: doesn't tally with the Zoe incidence data, which otherwise generally ties in well with ONS).

1a. Incidence

Zoe (KCL CSS) suggests incidence is slowing after a steep rise, whereas ONS and Imperial (REACT1) show sharp recent rise.

imperial.ac.uk/media/imperial…
1b. Incidence

Note sharp age distinction in ONS / REACT1; if you favour the "GB Declaration" approach (see below) you would want the difference between young and old incidence and trajectory as great as possible
