"Hi JVT. It's a bit late; what's up?"

"Steve, we need your help. Bloody medics are kicking off about the guidance change. They're refusing to see patients without FFP3"

"I thought the airborne HCID declassification was meant to sort that?"

[*Unverified date]
"Seems not. Twitter is kicking off; probably the source for this. Too many cottoning on the the fact that coughing releases aerosols & these have to be assumed to be infectious"

"Shit. We don't have enough even for ICU right now; what do you need from me?"

"A letter"
"Oh?"

"CAS Alert. You know; immediate national access all areas"

"Sorry, of course. Sure. When do you need it?"

"Saturday [28th] at the latest. Think you can do it? It'll need to be convincing on the IPC. But don't worry, @doyle_yg is on side, as is @AoMRC President"

Canada admits aerosols are major source of COVID-19 transmission after nearly two years of denying it wsws.org/en/articles/20…
β€˜The PHAC’s belated admission constitutes a devastating indictment of the political establishment’s prioritization of corporate profits over human life, which has gone hand-in-hand with a systematic repudiation of a science-based response to the virus.’ @trishgreenhalgh @Ozbilgin
Guidance change β€˜on the quiet’: sound familiar?

We know health workers are high risk for #COVID19

High quality PPE can protect us, but filtration masks hurt like hell, cost £££ and are bad for the environment

What's the answer?

We show PAPR like @PeRSoPPE are well tolerated, sustainable and safe

1/
frontiersin.org/articles/10.33…
After rolling out @PeRSoPPE at @UHSFT we asked HCWs about their experience, and it was much preferred for comfort and feeling of safety over other forms of PPE

Patients (particularly the elderly) preferred it too

(thanks Paul Elkington MBE for being such a glamorous model)

2/
An economic analysis found that they are more cost efficient than filtration masks, or a mix of filtration + surgical masks over almost all scenarios

Also significantly reducing waste (we can be safe and not kill the turtles🐒)

#COVIDisAirborne: For Dummies

βœ… How to convince any IPC team still stuck on droplet & AGP viral transmission dogma

1. VIROLOGY LOGIC:

SARS1 was airborne, so SARS2 is airborne.

Simples!

That's why @WHO didn't want to call it SARS2, see?
1a) Need another reference?

Try this: 2013, co-authored by our very own JVT & Lisa Ritchie, Head of Infection Prevention & Control @NHSEngland

How were they ever happy letting anyone on a SARS2 ward without FFP3? πŸ‘‡
2. HUMANS RELEASE AEROSOLS DURING NORMAL PHYSIOLOGICAL ACTIVITIES WHICH RESULT IN SUFFICIENT ENVIRONMENTAL AIR CONTAMINATION TO CAUSE INFECTION VIA INHALATION

Reference?

1966 ok? πŸ‘‡

At #FreshAirNHS we've pushed for airborne precautions for an airborne disease for a while, but the UK guidance has lagged behind - and now suggests NHS trusts must make their own decision.

@CUH_NHS decided to use FFP3 respirators for COVID-19 care, and now provide data. 1/
A simple swap of surgical masks (droplet) for FFP3 (airborne) appears to have eliminated the excess risk of infection from working on a red ward - from what was a 47-fold increase. 2/
Also notably, cases in red ward staff were not associated with community transmission; whereas on green wards the link was seen - a strong suggestion that "red" staff infections prior to FFP3 use were from their patients. 3/

'This evidence base supports the conclusion that widespread use of surgical and homemade face masks among the public can have a significant mitigating effect on the spread of Covid-19.'

Depressingly predictable, but with a twist πŸ™‚:

'Dr Yvonne Doyle, Medical Director at PHE, said: β€œNHS staff are under immense pressures and their safety has always been our highest priority.'
#FreshAirNHS #COVIDisAirborne
'The NHS Infection Prevention Control group has reviewed the latest evidence and has advised that PPE SHOULD CONTINUE TO BE WORN as laid out in the current IPC guidance, with FFP3 masks required for staff undertaking clinical aerosol generating procedures.'

The twist?
PHE IPC guidance, p2:

'Please note that this guidance is of a general nature AND THAT AN EMPLOYER SHOULD CONSIDER THE SPECIFIC CONDITIONS OF EACH INDIVIDUAL PLACE OF WORK AND COMPLY WITH ALL APPLICABLE LEGISLATION, including the Health and Safety at Work etc. Act 1974.'

So?
