The language (tending towards hyperbole - my interpretation) here is not that of a scientist, but we’re none of us free from this, I guess!
@dgurdasani1 like you I’m concerned about this PHE-derived narrative, particularly when conclusions defy physical laws.
/1 Image
Physical laws in a mo:

‘Antibody seroprevalence rates in students & staff were generally similar to regional community rates, both at the start & end of the Autumn term, albeit with wide confidence intervals.’

Looks like ‘direction’ of infection from students over time, no?

Physical laws:

1. Is there any difference in SARS-CoV-2 viral load comparing children & adults?

Answer: No

nature.com/articles/s4159…
Physical laws:

2. Is there any difference in aerosol / airborne particle release comparing children & adults?

Answer: No
Physical laws:

3. Are there unique characteristics of school environments that introduce ‘clinically important’ mitigations against airborne pathogen transmission?

Answer: Not in the UK, no.

Crowded, enclosed, poorly ventilated.
Finally, what has been the impact of the JCVI’s decision to expand the seasonal flu [another airborne pathogen, even accepted by WHO 2019!] vaccine to school age children, 2013 onwards?

Answer: a significant & protective effect in adults.

So next time you hear a PHE linked figure explain that schools are NOT sites for SARS-CoV-2 epidemic amplification, please ask them what IPC controls are in place: their statement will only hold for those implementing rigorous airborne mitigations.
End.

‘…ask yourself if the authors are truly trying to inform their readers or if they are instead trying to advance a narrative that would be undermined if they fully enumerated how COVID-19 has harmed children.’

Is UK Paediatrics #SoMe governance dead? When will its leaders act against medics pushing misinformation narratives?

‘Doctors writing about COVID-19 and children have an obligation to inform their readers of essential facts.’ @jeremyphoward 👏👏

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...

“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.'

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'.
