A short thread on the latest data on SCHOOLS and numbers of cases in different age brackets as we prepare to dispense with facemask on Monday.
TL;DR Cases in school age children are relatively flat, but the number of respiratory outbreaks recorded by PHE is increasing.
1/8
As usual, I will preface the thread by looking at numbers of lateral flow tests, which have remained relatively flat for the last few weeks.
This suggests any significant rises or falls we see in the case data probably reflect genuine rises or falls not changes in testing.
2/8
Cases in over 60s (brown) and 20-59s (blue) have continued to fall.
Cases in under 20s saw a slight rise when schools went back (possibly testing related) and have been flat or rising since then.
3/8
Breaking the under 20s into 5-year age groups, we can see all groups are either flat or rising slightly. Cases in the 15-19 age-range have fallen slightly since reopening, but cases in 10-14 year-olds have risen.
4/8
PHE data broken down by year group suggests almost all age-ranges have seen small increases over the last 2-3 weeks, but rates are much lower than when schools went back in March, which are in turn much lower than in November/December.
5/8
Its a similar story for outbreaks of COVID linked to schools.
They are on the rise again since schools went back, but at lower levels than March and much lower than December.
6/8
So cases in schools seem to be flat or increasing slightly overall against a back drop of roughly constant level of infection across the country as a whole.
We will have to monitor the situation closely as measure are relaxed on Monday and face coverings are removed.
7/8
Is this is the right time to remove face coverings in school?
You can read our opinion piece in the @bmj_latest on "Whether the government “following the data” on face coverings in schools?"

With thanks, as ever to Bob Hawkins for his help preparing the data.

Today the Royal Society will meet to discuss “Fellows’ behaviour”. Without doubt the fellow they will primarily be discussing is Elon Musk.
The behaviour may range from his public dissemination of unfounded conspiracy theories to his attacks on the science
🧵
1/38
Musk is also an important figure (some would argue the most important) within a US administration that is laying siege to science and to scientific inquiry itself.

The new administration’s executive orders have restricted research, silenced climate scientists and cut funding, as part of a systematic targeting of the scientific community.

The populist right is damaging US science.

Here's what I think we should be doing to ensure that the UK (and indeed other non-US countries) does not suffer the same fate.

The United States is currently witnessing an unprecedented assault on its scientists and scientific institutions, driven by populist agendas that prioritise ideology over evidence.

These orchestrated attacks threaten the foundations...

... of evidence-based policy-making and scientific progress. Funding has been slashed, climate research censored, and public health is in jeopardy.

Watching the disaster unfold one step removed, UK scientists must not stand by but instead react to support our US colleagues

Silence will not shield scientists from the consequences of an increasingly hostile political landscape.

UK and other non-US scientists must act to support our US colleagues.

Here's what I think we should be doing...

Science thrives on collaboration and openness.

The people who practice science are committed to seeking truth and combatting falsehoods.

2/35
In an era where political forces increasingly seek to distort, suppress, or co-opt scientific knowledge for ideological purposes, the global scientific community must recognise that staying silent in the face of these challenges is no longer an option.

Fiona Fox’s recent article in Research Professional News cautions that expelling Elon Musk from the Royal Society could undermine public trust in science.
I disagree...
🧵

researchprofessionalnews.com/rr-news-uk-vie…
I think that this perspective overlooks the critical role that scientific institutions play in upholding ethical standards and defending the integrity of science, especially at times when science and scientists are subject to threats and intimidation from political institutions

It's imperative that scientists and their representative bodies actively engage in political discourse to protect scientific integrity, particularly when it is under direct threat, as has been clearly evidenced by recent developments in the United States

After hearing some underwhelming testimony last month at the #COVIDInquiry on the use of respirators, @trishgreenhalgh and I decided to write a rapid response to the @bmj_latest to set the record straight.
Here's what we wrote...

"Respirators outperform surgical masks; fit-testing is desirable but not essential"

Professor Susan Hopkins (UK Covid Inquiry, 18th September 2024) claimed that evidence for the superiority of respirators (which are made to an industry standard and designed to fit ...

closely around the face) over medical facemasks (which are not generally made to any quality standard and often fit loosely, leaving gaps around the sides) is “weak”.
She also claimed that respirators are of little use if they are not fit-tested.

As the UK’s general election campaign enters its final few weeks, we’ve already seen numerous examples of dodgy declarations, substandard stats and graph gaffs.

So I thought I'd write about the importance of numeracy to the functioning of democracy.
🧵
We can expect to see more questionable claims in the run up to polling day.
The factor that all these all these missteps have in common is that they involve the manipulation or misrepresentation of numerical quantities.
One of the most hotly disputed figures of the campaign so far has been the Conservatives’ claim that Labour’s policies will, as Rishi Sunak put it, “amount to a £2,000 tax rise for everyone”. Labour have rebuffed this figure, arguing that...
