“What we have got to do is work out some balance which actually keeps [Covid] at a low level, minimises deaths as best we can but in a way that the population tolerates..,” @CMO_England 1/4/21

137 HCW deaths since 08/20

HCWs tolerate FFP3 but only ICU teams get them: why?
'Dynamic CO-CIN report to SAGE and NERVTAG
Includes patients admitted after 01 August 2020
There are 104666 patients included in CO-CIN. Of these, 21177 patient(s) have died & 18043 required ICU. 62747 have been discharged home.'

‘Infection control guidance and Personal Protective Equipment (PPE) provision are out of date and are placing health and care staff at risk, an alliance of health professional bodies, Royal Colleges and trade unions said today.’

We are still waiting. 💙

Dear [INSERT MP]
I am writing to request your help towards highlighting the need for urgent revisions to the current PHE UK Covid-19 infection prevention & control (IP&C) personal protective equipment (PPE) policy for all “front line” health & social care staff.
To-date, three UK-based reports demonstrate significantly greater risk of SARS-CoV-2 infection and/or death in non-ICU UK patient-facing healthcare workers (HCWs):

The most recent (28th October) is from the BMJ (doi.org/10.1136/bmj.m3…), with data on 158,445 Scottish HCWs...
...(1st Mar – 6th June 2020) indicating that: "patient facing HCWs compared with non-patient facing HCWs, were at higher risk [of SARS-CoV-2 infection] (HR 3.30, 2.13-5.13)...after sub-division of patient facing HCWs into…front door, ICU, non-ICU aerosol generating settings...

Panel suggests WHO should have more power to stop pandemics independent.co.uk/news/world/ame…
Necessarily abbreviated! 👆

Full quote: As a healthcare worker, my overwhelming impression of the response of WHO teams to the SARS-CoV-2 pandemic is that they failed on the most fundamental aspect: i.e. truthfully describing its transmission characteristics.
/1
Through actively & persistently denying that SARS-CoV-2 transmission occurred via the airborne route, WHO teams have *amplified* the pandemic, caused huge waste in surface cleaning measures & allowed nation states' IPAC policies for HCWs & their population to remain...

'Our estimates are that in the post-intervention [FFP3] period there was a 37% reduction in staff off sick with Covid-19 even accounting for immunity. The effect of this multiplied across the entire NHS in avoiding staff sickness, long Covid, & even death would be enormous'
'In our study it is reassuring that the overwhelming majority of staff members (79%), following eight weeks of enhanced respiratory protection with FFP3, stated their preference to continue their use'

Not even 'DEATH BEFORE ACNE' here, @YouAreLobbyLud
Another notable finding: 10/11 HCWs who knew the reason for changing to FFP3 (i.e. increased @CUH_NHS staff sickness) wanted to continue using FFP3 after the study period.

I'm guessing you didn't even need to show them an IPAC 'disaster graphic' like this @mjb302? @microlabdoc

Catch me if you can: Superspreading of SARS-CoV-2
Highly readable: recommended.
h/t @microlabdoc cell.com/trends/microbi…
Theoretical mechanisms - differential glycosylation: 'SARS-CoV-2 produced in individuals with distinct blood groups may differ in their glycosylation patterns, which could impact the binding and susceptibility of SARS-CoV-2 in respiratory epithelium and subsequent transmission'
And just for you @MicrobiomDigest: 'These observations suggest that nasal microbiome communities can influence efficient airborne transmission of respiratory viruses'.

'The [WHO] process of developing evidence-based guideline documents for clinicians, public health experts & policymakers follows rigorous, standardized procedures, making sure that their compilation is transparent & based on evidence, & that any potential COIs are made explicit' Image
'The organization aims at making guidelines, when applicable, close to “real-time”, which it believes would be possible by using a “living guidelines” approach based on living systematic reviews and living recommendations' @microlabdoc Image
Dear @WHO IPC teams,
Based on recent [negative] peer review, I am looking forward to you revising the scope of the @F1000Research 'SARS-CoV-2 & the role of airborne transmission' living systematic review.

I am sorry I can only copy two lead authors directly, but I would like to thank all authors for acting on their high sense of responsibility towards improving public health.

I am also sorry I could not reply within the 7-day window you provided for 'stakeholder feedback'.
I hope you don't mind a Q?
Given:
- Epidemiological studies support airborne transmission
- Presence of virus RNA in the air, air vents/exhausts/ducts/filters
- Presence of virus RNA in exhaled breath
- Airborne viability up to 16 hours
- Presence of live virus in the air
