Consultant Cardiologist, Dr Rae Duncan (@Sunny_Rae1), was interviewed today on BBC’s Sunday Show.

In this thread 🧵, I’ve pulled out some of the key highlights.

Kudos to Martin Geissler (@mmgeissler) who had clearly done his homework in advance & asked excellent questions.

1/
Dr Rae Duncan kicks off by explaining that Covid is not ‘just a cold’.

She explains that, if we think of Covid simply in terms of the acute stage of infection, we are only looking at the tip of the iceberg…

…but the bulk of the iceberg lies beneath the surface.

2/
Martin: “In Canada, they’re finding if you’ve had 3 or more Covid infections, you’ve got a 38% chance of getting Long Covid. Can that be right?”

Dr Rae Duncan explains how many studies show that, the more times you get infected, the higher your risk of developing Long Covid.

3/
Martin: “Can you just as easily get organ damage, brain issues, heart issues from Long Covid if you’re young & healthy?”

Dr Rae Duncan explains how EVERYONE is at risk. Many of her Long Covid patients were previously young, fit & healthy; some were even amateur athletes.

4/
Dr Rae Duncan explains how this Winter has been devastating for some of her patients as so many have been reinfected with Covid…

…and all the hard work put in to try to get them better, to get them back to work or back to school, has all been completely undone again.

5/
Martin: “Are we taking this seriously enough as a country?”

Dr Rae Duncan explains how our government need to start listening to the WHO advice.

If we don’t get a handle on the high Covid transmission rates, hundreds of millions are going to require longer term care.

6/
Dr Rae Duncan explains how studies have repeatedly shown that cleaning the air (by improving ventilation & air filtration) can significantly reduce Covid outbreaks in schools & improve school attendance rates…

…and it protects against other airborne pathogens too.

7/
Martin: “Are we too laissez-faire about Covid at the moment?”

Dr Rae Duncan explains how she’s very concerned about the longer term implications of Long Covid.

Economic modelling already shows that Long Covid might be costing the UK economy billions of pounds EVERY YEAR.

8/
Dr Rae Duncan wraps up by explaining that we have to learn to live with Covid SAFELY…

…and that should start with basic measures like clean air in schools & hospitals.

Finally, Martin gives a poignant anecdote about one of his camera crew who is suffering from Long Covid.

9/
A massive thank you to Dr Rae Duncan (@Sunny_Rae1), Martin Geissler (@mmgeissler) and @BBCScotland for this brilliant interview, raising awareness about the devastating impact of Long Covid.

“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

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.
