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.

“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.

LONG COVID IN UNIVERSITY STUDENTS

🚨40% of the undergrad students reported brain fog due to COVID-19.

🚨37 % of the undergraduates exhibited impaired cognition up to 17 months post-infection.

🚨Brain fog appeared to affect the distinct prefrontal haemodynamic patterns. Image
This study was conducted by scientists at the University of Otago (NZ) who were looking to investigate the cognitive effects of COVID infection in a population highly representative of young adults: undergraduate university students.

Today, in honour of #LongCovidAwarenessDay, I’m sharing a series of short videos from Dr Rae Duncan (@Sunny_Rae1) about the ongoing impact of Long Covid.

1. WHAT IS LONG COVID?

Long Covid is a multi-systemic inflammatory condition that can affect almost every organ of the body.
2. WHAT ARE THE PRINCIPAL MECHANISMS & MANIFESTATIONS OF LONG COVID?

Dr Rae Duncan explains some of the key manifestations of Long Covid, including:

▪️immune-mediated issues

▪️abnormalities of the autonomic nervous system (the nerves which control things like our heart rate).
3. WHAT ARE THE MAIN SYMPTOMS OF LONG COVID?

Dr Rae Duncan discusses some of the most prevalent symptoms of Long Covid, such as fatigue and post-exertional malaise.

There are over 200 recognised symptoms of Long Covid though, so each patient may experience different symptoms.

⚠️ IPC GUIDANCE

Newly-appointed Health Minister @AshleyDalton_MP has just responded to a question from MP @_Chris_Coghlan.

Chris asks when the NHS IPC manual will be updated to reflect the latest science on AIRBORNE transmission.

Let’s take a closer look at Ashley’s reply… Image
The key bit is highlighted in yellow here:

“Should new evidence emerge that warrants updates, the guidance will be reviewed & revised accordingly by NHS England & UKHSA to ensure the highest standards of infection prevention & control are maintained across healthcare settings.” Image
Well @AshleyDalton_MP, new evidence HAS emerged.

It’s not even new news as we’ve known about it since 2020!

There’s not a single credible scientist who still denies that Covid is transmitted via the AIRBORNE route.

Please listen to independent expert witness Prof Beggs here ⬇️

I wonder why so many people who’ve had Covid might be suffering with ‘anxiety’ 🤔

Hmmmm, let me think…

Could it be because Covid infections cause brain inflammation which triggers a plethora of neurological symptoms, including depression, anxiety & cognitive dysfunction?
The symptom may be ‘anxiety’ but this can often be the first sign of underlying neurological damage caused by COVID infections.

Patients affected may also be struggling with cognitive dysfunction, memory problems, difficulty concentrating etc.

This video helps explain why ⬇️
Here’s a fascinating post from neuroscientist @DaniBeckman which explains a little more about the damage that COVID can cause within the brain, disrupting neuronal circuits and contributing to neuronal loss. Image

“WHY ARE YOU STILL MASKING?”

The folks at the @TheWHN have put together a really excellent set of science-based answers to various questions about why you’re still wearing a mask.

(Even if you’re not still masking, you might be interested in the answers).

Let’s take a look…🧵 Image
1. “Isn’t the pandemic over?”

Short Answer: The World Health Organization (WHO) declared the emergency phase over, but that doesn’t mean the pandemic itself has ended.

(h/t @TheWHN) Image
2. “But you’re not high-risk, so why bother wearing a mask?”

Short Answer: Because preventing transmission matters for everyone, not just people in vulnerable groups.
