Quick THREAD on current England situation:

TLDR overall cases falling but case positivity pretty flat... cases rising in school children but falling in young adults.

Hospitalisations remain relatively high. Simple things now will prevent things getting worse. 1/10
First off - some excellent news: vaccine uptake in 16/17 yr olds is very good and many 20-30 year olds are now fully vaccinated. I have no doubt this is having a big impact on cases! 2/10
Now some less good news... Hospital admissions have fallen slightly this week (good) but remain relatively high, as does hospital occupancy at just over 6,000 inpatients. 3/10
While these nums are way less than Jan peak & ~5% of current occupancy, they are still a lot of patients. And many are very sick and that's a problem.

20% of all critical care capacity right now is Covid patients & that restricts a strained NHS ability to do other work. 4/10
We have plateaued at ~110 deaths a day reported in England - that's a lot and 6x higher than this time last year before we had vaccines... This shouldn't be the new "normal"

see @HelenRSalisbury & @martinmckee 's BMJ blogs

So to cases... these have fallen in England this past week - which is good but positivity rates have been falling *much* more slowly, which suggests that at least part of this drop is reduced testing.

ONS infection survey to 11 Sept also found flat (but high!) cases. 6/10
If we look at ages, cases are highest & flat or rising in 5-15 year olds (as are their positivity rates)

Falling a lot in 20-29 yr olds (vaccination?!) and flat or falling in 30+. Hopefully combo of hot weather, high vax, many still being cautious.

But what's that hotspot?7/10
Highest cases in country right now are in Leicestershire - where schools went back a bit earlier on 23rd August.

Cases in 5-15 year olds there are soaring while falling in other young adults and flat in older adults (for now). 8/10
So what does autumn hold? Well SAGE are worried that schools + uni + return to workplaces could lead to more sustained high cases.
They suggest some simple things that could be done NOW to prevent this.

@IndependentSage also have a 9-point plan to prevent a new spike - and that also keeps the economy open.

Govt is currently doing very little to prevent the pandemic worsening. They didn't listen to SAGE (or us) a year ago - let's hope they do now! 10/10

THREAD:
It's tiring to be attacked as if I (and others) am an "extremist" on covid or with suggestions that I'm a mouthpiece for others... when actually I'm very mainstream and it's UK policy that isn't. 1/10
The government's science advisors, SAGE, have literally just warned that we are risking a rough winter through not implementing simple mitigations now
assets.publishing.service.gov.uk/government/upl… 2/10
The British Medical Assocation have this week highlighted the ongoing burden of Covid on an NHS that is understaffed, underfunded and exhausted.

THREAD: Was on @BBCNews earlier discussing yesterday's SAGE consensus statement particularly their advice that relatively minor measures could prevent a big autumn surge

assets.publishing.service.gov.uk/government/upl… 1/4
Almost a year ago SAGE advised a 2 week circuit break - we don't need that now with vax BUT we do need *something* in addition to the vaccines.
Alongside masks & some continued homeworking, there are clear things we could do that will help that are NOT RESTRICTIVE AT ALL 2/4
The government plan B does not say what "unsustainable pressure" on the NHS is... but the NHS is already extremely stretched and understaffed - and people are exhausted.

25% of current ICU beds are already Covid patients. We need to protect our NHS not keep piling more on. 3/4

THREAD on latest PHE report on vaccine waning (and need for boosters):

Important new report from @PHE_uk on vaccine waning by age and at risk status - basically yes there's waning, but still good protection against severe disease for most people. 1/9
Firstly, protection against symptomatic infection starts waning against Delta (orange) about 10 weeks after 2nd dose (70 days).

Waning with both vax, but AZ starts and ends with lower protection. 2/9
Protection against hospitalisation is much higher and stays stronger - particularly for Pfizer. Some waning in AZ from about 20 weeks (5 months/140 days) after dose 2 but even so efficacy remains at about 80% for AZ after 20 weeks 3/9

QUICK THREAD on UK covid situation...

Cases in the UK are going up. We've had high cases for several months now - over 2.7 million confirmed cases since Delta took over in mid May. And no sign of coming down any time soon. 1/9
By nation, Scotland has by far highest rates right now (800/100K people/week). Then come NI & Wales - but NI is decreasing & Wales increasing. Plus Wales has v high positivity rates - that's bad.
England is flattest & lowest right now. Everywhere way higher than year ago. 2/9
Geographically we can see the high numbers in Scotland, NI and Wales. In England cases are highest in the North and parts of Midlands (again), and the SW. English cases flat in adults but rising steeply in under 20s... 3/9

THREAD on Scotland, cases, schools and hospitals:

TLDR: cases *and* hospitalisations in kids are much much higher than they've ever been.

13% of children are off school (for any reason).

England likely to follow suit... Protect schools. 1/7
Schools in Scotland were back by 19 Aug. Scotland moved to its final level of opening on 9 Aug.

Cases in 15-19 year olds shot up week after 9th & carried on increasing after 19th. Most recent week has seen a fall.

Cases 2x previous peak in July and 6x high than Jan peak. 2/7
Of course, many 15-19 year olds are not in school tho.
Looking at Under 15s, we see rise in cases in summer term, drop over holidays and then they have shot up this term. 5x higher than July peak. Last week plateaued... 3/7

THREAD on what other countries are doing in terms of vaccinating 12-17 children... who's doing it and why?

TLDR: UK one one of the v few high income countries left that isn't 1/20
Almost first off the block in vaccinating 12-17 yr olds were USA and Canada in May.

Canada emphasises the importance of vax to protect kids from acute Covid, prevent long term impacts from covid (eg long covid) and reduce transmission to others.

canada.ca/en/public-heal… 2/20
US Centers for Disease Control (CDC) published a risk benefit analysis, projecting forwards for 120 days using May case rates & estimating how many infections, hospitalisations, deaths were prevented vs new harms from myocarditis. 3/20
