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?

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

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... theguardian.com/politics/artic…
Politicians will get away with the things we forget, so here is a list of things to remember about the government's record on covid: 1. Over 230,000 died from covid in the UK. 2. They partied while we weren't allowed to see our loved ones. Thousands died alone.

3. They were too late taking action in spring 2020. 4. They delayed again in autumn of 2020. 5. They waited until they had no other choice in winter of 2020/2021. 6. They funnelled cash to their mates through the VIP lane. 7. PPE provided to our healthcare workers was inadequate.
8. They failed to heed the warnings in the pandemic planning exercises. 9. The promised a protective ring around care homes and instead sent infected patients to them from hospitals.
There are many more, these are just the most egregious.
A water company released sewage into the stream that runs into the beach where we were holidaying. I didn’t like the idea of swimming in the sea after that, so I tried to sue to water company for spoiling our holiday. This is what happened…

First up, cards on the table, I am a keen outdoor swimmer. I swim with a group of friends most weeks in our local stretch of the Thames. Come rain or shine, winter or summer, there are usually at least two of our number bracing the river waters north of Oxford.

We do so cautiously, however, especially in winter when it has been raining heavily and it is almost guaranteed that sewage will have been pumped into the river a few miles upstream.
The giveaway as to whether there has been a discharge or not is the smell.

It's π-day (3/14 in US date format) - the international day of mathematics.
But people often ask me why π is important. Why do we care about calculating more and more digits?
In short, "What is the point of π?"
Well, here is the answer...

The number of digits after the decimal place in pi extend off into the distance (these are the first 50).
Truncating π's decimal expansion after the second decimal place (3.14) is sufficient to specify the date of pi day.
With 11 digits of π we can calculate the circumference of the Earth from its radius with an error of just a mm.
With 38 digits we can compute the circumference of a circle encompassing the whole of the known Universe with an accuracy to within the radius of a hydrogen atom.

But do you know why we have leap days at all and how often exactly they come around?

This exceptional day has been associated with weird and wonderful traditions over the years: from the wildly outdated notion that 29th of February is the only day when women can propose to men, to the Leaper Year festival held in Anthony, New Mexico.

As a rule of thumb, leap days come around every four years. But there are exceptions to this rule. For example, at the turn of every century we miss a leap year. Even though the year is divisible by four, we don’t add a leap day in the years that end in 00. But...
