COVID HOSPITALISATIONS, a thread🧵

In case anyone still believes that changing the Covid testing policy in hospitals back in April hasn’t really affected the hospitalisation data, this chart is just for you.

Please take a good look at it.

It tells a very interesting story… Image
You can quite clearly see the point where Covid hospitalisations decouple from the PCR positivity rate…

…and it’s no coincidence that it falls on EXACTLY 1 April 2023. Image
1 April is the date that Covid testing policy in hospitals changed.

Since that date, there has been no routine Covid testing in hospitals, even for those with Covid symptoms. Image
Since 1 April, PCR tests have only been given to those where having a Covid diagnosis would change their prescribed clinical treatment plan.

Even clinically vulnerable patients eligible for anti-viral treatment are only given an LFT test.

Image
And yet, despite there now being no routine Covid testing for hospital admissions, we’ve still seen a rapid increase in Covid hospitalisations over the last 3 months.

It’s not just increased a bit; it’s QUADRUPLED! Image
When we look back a bit further, the data appears more reassuring as the recent hospitalisation figures are nowhere near the peaks we used to get.

But remember, prior to 1 April, every single hospital admission would be routinely tested for Covid.

It’s like comparing 🍎 & 🍐! Image
If there hadn’t been the change in testing policy, perhaps that trough in July would be at the same baseline as other recent dips?

If you extrapolate a 4x increase on top of that, the numbers start to look extremely worrying.

But, of course,without testing, we can’t be sure. 🤷🏻‍♀️ Image
Either way, this 4-fold increase in Covid positive hospital admissions, despite there being *no* routine testing, is quite something.

But what’s even *more* remarkable is that there’s not even been any noticeable increase in PCR testing volumes (grey bars on chart below).

👇🏻 Image
The thing which has shot up massively is the % of PCR tests which give a positive result.

It’s just peaked at 16.9%.

With the same number of tests but a big increase in positivity rate, that tells us we’re almost certainly missing a LOT of Covid hospital cases in those figures. Image
Rumour has it that some hospitals have even been told they’re not *allowed* to test patients for Covid.
But even without much testing, doctors on the front line are confirming that they’re definitely seeing a marked increase in Covid cases…
There’s two aspects to this story though:

1) the data and the fact that we’re not seeing the full picture here.

But more importantly:

2) the real-world impact of all those hospital patients who are infected with Covid but haven’t been tested for it.
The really tragic thing is that it’s no longer deemed necessary to test to identify Covid positive patients because there are not really any infection controls for Covid anymore.

There are no isolation wards for Covid patients.

They don’t test them. They don’t isolate them.
If you have to be admitted to hospital, it’s quite possible there will be someone on your ward with Covid.

They may not even know it themselves as there’s hardly any testing anymore…
Even if there’s not someone on your ward with Covid, maybe there is on the ward next door.

And then you’ve got doctors and nurses who are busily doing their jobs, moving from ward to ward, patient to patient, seeing dozens of sick patients a day… day in, day out…
…but those doctors and nurses who have been attending to all those sick patients won’t be wearing a face mask.

Masks are no longer required in the vast majority of hospitals.

Apparently it’s more important to see doctor’s smiles 😁 than to prevent the spread of infection. Image
It’s little wonder that Covid is spreading like wildfire through hospitals.

Part of the reason it spreads so easily is that people are highly contagious just before the onset of any symptoms.

In fact, nearly 60% of all Covid infections are from people with NO symptoms (yet).
Image
Without routine testing, these asymptomatic cases will of course go undetected.

But it’s even worse than that.

They’re not even protecting against SYMPTOMATIC transmission!

Healthcare workers who have Covid symptoms and/or test positive are told they should still come to work. Image
Surely the one place that people should be afforded a higher level of infection control is in hospitals…

…a place where people go when they are sicker, weaker and more vulnerable than they would usually be.

Isn’t that the very essence of the Hippocratic Oath? Image
Numerous studies tell us that clinical outcomes from hospital-acquired Covid infections are pretty dire, far worse than those who remained infection free.

“1 in 5 people who caught Covid in hospital, died with it.”

This isn’t just impacting patients, it’s impacting doctors too.

@TheBMA recently released a report outlining the devastating effect which Long Covid is having on many doctors’ lives.

It ended with a powerful quote from @fearnley_k 👇🏻

bma.org.uk/bma-media-cent…
Image
This week, the Covid Inquiry has been hearing evidence from doctors saying they didn’t feel adequately protected during the early stages of the pandemic.

But Covid is not over.

This is still happening in hospitals TODAY.

And there are even LESS mitigations now than back then.
Image
In Scotland, doctors formally wrote to the Government in July opposing the withdrawal of face-masks in healthcare.

They state that they consider this decision to be “flawed and dangerous”.

If you’ve read this far, hopefully you understand why we need to do more to prevent the spread of Covid in hospitals.

Please help us by signing & sharing this petition to bring back #MasksInHealthcare:

✍🏻

We need to hit 10,000 signatures by 12 October! petition.parliament.uk/petitions/6363…
Image
We also need to filter the air on wards to remove viruses and other airborne pathogens…

…just like they are doing in the East Suffolk & North Essex NHS Foundation Trust.

This should be rolled out across ALL healthcare settings.
Everyone should have the right to access safe healthcare.

Hospitals must be made safe again.

Below is a Open Letter written by the distinguished team of experts at the John Snow Project which you can use to help advocate for better infection controls in your local hospital 👇🏻

@kallmemeg Actually, I should say trends are still “reliable”, rather than “good”…

…because the trends actually don’t look too “good” at all, do they?

It’s been a while since we’ve seen hospitalisations quadruple in the space of just 3 months.
@kallmemeg By the way, I’m not sure if you saw my reply to your kind offer to take me through your data sources on another thread. 👇🏻

Please could you let me know if I’ve missed any data that allows us to estimate the current prevalence of Covid.

I’d really like to learn more.

“We're not just running out of cubicles; we're running out of corridors.”

“It feels like [Winter] is going to be armageddon, to be honest. We’re already full.”

This entire article is frankly horrifying. And yet, nothing is being done to mitigate it.

independent.co.uk/news/health/nh…Image
Analysis of NHS data by the RCEM, shows that from Jun-Sep 2025, over HALF A MILLION patients had an A&E stay of over 12 hours from their time of arrival in England.

This is MORE than the entire winter of 2021-22, during which the UK experienced one of the worst Covid waves. Image
In the latest weekly figures, there were 188 people Covid deaths across the UK.

188 Covid deaths. In just one week.

3,866 Covid deaths so far this year.

COVID INQUIRY

Prof Whitty on VENTILATION in schools:

“It's an uncontroversial statement from an epidemiological point of view to say that improving ventilation in schools would be a good thing […] The advantages of ventilation are very substantial.”

So why aren’t we doing it?
Data from the national schools air quality monitoring project (SAMHE) shows that ventilation rates in schools drop to just 3.8 litres per sec per person in colder weather.

This is far BELOW the minimum UK guidance of 5-8 litres per sec per person.

When will the govt fix this? Image
For more clips from Prof Chris Whitty’s appearance at the Covid Inquiry today, please take a look at this excellent thread from Clinically Vulnerable Families (@cv_cev):

LONDON MAYOR INVESTS £2.7M IN AIR QUALITY FILTERS FOR SCHOOLS

I’m SO excited about this! I hope there’s lots of press coverage about it over the coming weeks.

It’s not just an issue in London though.

ALL children have the right to breathe clean air.

london.gov.uk/mayor-invests-… x.com/_catinthehat/s…Image
Here are some more details about the project:

▪️At least 200 schools across London will receive HEPA air filters

▪️Filters used for this initiative will be Blast & Blast Mini devices from @SmartairUk

▪️Participating schools will receive one filter per classroom where possible
@SmartairUk I’m particularly pleased to see that the @MayorofLondon has chosen SmartAir air filters for this initiative.

I’ve done a lot of research on air filters & the Blast & BlastMini are two of the very best air filters for schools.

High CADR & low noise make them the perfect choice! x.com/_catinthehat/s…Image

Why do schools need to tackle poor VENTILATION in classrooms?

Because nationwide monitoring of UK classrooms shows that ventilation drops to appallingly low levels when outdoor temperatures drop & windows are closed.

Poor ventilation means airborne viruses spread like wildfire. Image
And when those airborne viruses spread like wildfire, guess what happens to pupil & teacher absence rates?

Unsurprisingly, they sky rocket! 🚀

Here’s what happened to absence rates in the 2023/24 & 2024/25 autumn terms (vs the pre-pandemic average shown by the dotted line) ⬇️ Image
Now look what’s happening to illness in 15-24 year olds right now… 👀

Covid rates have been steadily rising and are now at the highest point in over a year for this age-group.

Meanwhile, flu has seen a dramatic rise about a month earlier than usual.

The DfE have published guidance on reducing the spread of illness this Winter.

Much of it focusses on things like handwashing & catching sneezes which WON’T stop airborne illnesses spreading.

BUT I’m pleased to see a whole section on VENTILATION, CO2 MONITORING & AIR FILTERS. Image
Link to this newly published guidance can be found here:

educationhub.blog.gov.uk/2025/10/reduci…
The joint unions have also just released newly updated guidance:

“GOOD VENTILATION IN SCHOOLS & COLLEGES AND HOW TO ACHIEVE IT!”

This excellent guide sets out 5 simple steps which schools should be taking to monitor & improve ventilation in classrooms.

“LONG COVID IS FUELLING A MENTAL HEALTH CRISIS IN CHILDREN”

🚨Nearly 40% of children with Long COVID reported anxiety or depression; half had no prior diagnosis.

🚨Mental health impact was comparable to that of serious chronic illnesses like cancer.

neurosciencenews.com/long-covid-chi…Image
Meanwhile, more than 500 children a day in England are being referred to NHS mental health services for anxiety, more than DOUBLE the pre-pandemic rate…

…and yet, the impact of repeated COVID infections on children is never even considered as a contributing factor. Image
There are so many studies about the detrimental impact that Covid has on the brain…

…how the brain inflammation can trigger neurological symptoms such as depression & anxiety.

I don’t understand why this is just being ignored by the mainstream media.
