as many are having to do, fight through the courts - some, 6 years after infection at work as a direct result of the Government's failure to provide them with the respiratory protective equipment they should have had.

Our doctors, nurses and other healthcare workers were the frontline in a war against a pandemic virus.

They have to wait for an intransigent Secretary of State to put pen to paper to enable benefits to be paid

OR...

They do not have to prove negligence for this. It is sufficient that they were there and they got injured (period!). And of course they truly deserve it.

My own personal view is this:

If a soldier is injured in a combat zone they are automatically awarded compensation under the Armed Forces Compensation Scheme ie tax free lump sum and regular payments thereafter.
It is a 'no fault scheme'.

This joint letter from RCN and BMA says it all.

COVID-19 and Occupational Impacts

www.gov.uk/government/p...

By no means all L-C conditions, but a good start. However, the IIAC can only make recommendations. It requires sign-off by the Secretary of State for Work and Pensions.
It is an absolute disgrace that that has not happened.

You raise a very good point Esther.
It should be the case in the UK as well. But it isn't.
In Nov 2022 the Industrial Injuries Advisory Council submitted a Command Paper to Government recommending that certain Covid-19 sequelae be prescribed as occupational diseases for which benefits would be paid.

Long Covid ruled as occupational disease in nurses - Switzerland Long Covid confirmed as an occupational disease in nurses.

"FROM THE OLYMPICS TO NASA, WEARING MASKS IS BACK - EXCEPT IN HEALTHCARE

Brilliant article on how masking is increasingly popular with Olympic athletes, actors & astronauts wanting to avoid illness…

…but sadly, in hospitals, masking is rare & those who do are often gaslit.

Have noticed an excellent opinion piece in the Irish Independent by the brilliant Tess Finch-Lees.

Love the final paragraph about her friend Meg...
She deserves a gold medal!!

So may be better to just put in a fresh FoI saying what actual readings you want.

But if you ask for too much they may reject the FoI using the excessive cost exemption.

Good luck, but sorry I can't advise further.
Kind Regards. David

And perhaps limit the request to, say, the max CO2 recorded in each room over, say the last year.

However they may just say in the internal review that you didn't ask for this data in the first place and find in favour of their original response.

04.02.2026 21:32 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

But I think you'd have to limit what you ask for as it would be unreasonable to ask them to provide all results in all rooms forever!

So if you have a concern about a particular room or rooms, you'd have to say which.

04.02.2026 21:31 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I think they've answered Q1 to 4 in a way that it would be difficult for you to challenge.

But Q.5 you asked for results and they haven't actually given you any!

So you can go back and request what they refer to as an 'Internal Review' (a sort of 'appeal').

Hi Nicole
I do remember our previous correspondence.
I'm afraid that this sort of air quality management is not something I deal with and I can't advise over Social media going forward I'm afraid.

However, I've had a look at the FoI reply.

Well now, there's a thought...!

On reflection I somehow don't think they'd have me lest I put a CATA amongst the pigeons.

Thank you so much.
I can assure you that we are still very much on the case.

You're so very right Michiel. If you or loved ones are in that awful situation can I offer sincere condolences.
Sadly I have many friends suffering with Long Covid.
I guess that, in a way, I was alluding to that with my comment about 'onward transmission' but perhaps unclear.
Hope no offence caused.

Millions of people have died because of this widespread incompetence of the #WHO!

Thank you for adding more information about the outrage of someone who understands public health, like me.

To their eternal shame they failed to do so and thousands died - not to mention the potential for onward transmission to patients.

An analogy would be "bees spreading pollen between flowers they visit" vs "medics spreading virus between patients they visit in a hospital".

I hope this helps.

His paper "A Rosetta Stone for Understanding Infectious Drops and Aerosols" became like a bible to some of us fighting to get WHO and Governments to understand the most rudimentary concept of airborne/aerosol transmission of Covid-19 and protect healthcare workers appropriately.

So they do REDUCE (BUT NOT ELIMINATE) the risk of infection to others - but any reduction in risk is a good thing.

By the way, the 50% figure comes from Dr Donald Milton, one of the most distinguished scientists in the field.

11.01.2026 08:45 πŸ‘ 3 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

They effectively retain droplets from nose/mouth and reduce the amount of the tiny, almost invisible aerosols by about 50% - the rest will escape around the edges as they are not tight-fitting to the face.

11.01.2026 08:44 πŸ‘ 9 πŸ” 1 πŸ’¬ 2 πŸ“Œ 0

Yes we do know.

Non-respirator masks such as surgical/medical masks (aka "baggy blues") do help to stop the spread from an infectious person to others around them.

That's why surgeons (etc) wear them in healthcare.

Hi Camille
Actually it was me who took down my message - to replace with a longer one.
I see you have seen it & reposted. Many thanks

I hope that the former members of the "IPC Cell" and those who oversaw their secretive activities during the height of the pandemic are taking careful notice.

Ditto: Their supporters and current proponents of the big lie that surgical masks protect against an airborne disease.

This letter, signed by so many experts and representatives of millions of healthcare workers around the world (including Dr Barry Jones, Chair of CATA, {Covid Airborne Transmission Alliance}) must surely persuade WHO to come clean and change policy.

Marie Antoinette, Queen consort of France.

Marie Antoinette, Queen consort of France.

The situation brings to mind a historical analogy:

Marie Antoinette: β€œLet them eat cake”

WHO/World Health Leaders: β€œLet them breathe virus”

PS For the avoidance of doubt: I’m not recommending the same fate for WHO/Health Leaders as Marie-Antoinette…!
