Evidence will be presented that:

• the relevant Government departments (PHE/DHSC) are seriously misleading healthcare workers by referring to surgical masks as ‘PPE’,
• this misinformation leads workers to a false belief that they are being adequately protected, and

• this seriously compromises the health and safety of these workers and endangers their lives @doctorsdilemma @DrPieterPeach @YouAreLobbyLud

My favourite part:

8. THE ‘UNIVERSAL ETHICAL CODE FOR SCIENTISTS’

@Sir_David_King what do you think: have our ‘politician-scientists’ upheld these values, or have they chosen to ignore wrong-doing? @chrischirp @IndependentSage @globalhlthtwit
But the whole document is genius:

“It takes more than a convenient ‘re-interpretation’ by PHE to overturn a definition that has been the law of the land for thirty years and make something that is not PPE into PPE.”
@PHE_uk @NHSEngland @KamranAbbasi @fgodlee
the HSE provides advice specifically for HCWs: “Until the cause & route of transmission are known, in addition to standard precautions, infection control measures for inpatients should include...airborne precautions, e.g. use of FFP3 filtering masks for persons entering the room”
Take a moment. It’s worth it. 👇
And clearly, but incredibly:

‘They [@WHO, PHE, @DHSCgovuk] do not, DESPITE THE MOUNTAINOUS WEIGHT OF EVIDENCE NOW ASSEMBLED, seem willing to accept that aerosols produced by natural means (coughing, sneezing, talking, etc.) are relevant in disease transmission.

‘HMG PPE guidance on the indications for use of FFP3 respirator relies on two assumptions. First, that its list of AGPs & high-risk areas are exhaustive. Second, that the droplet theory of SARS-CoV-2 transmission is correct.’
@TheBMA @theRCN @KGadhok Image
‘If either of these two postulates are incorrect & the role of aerosolisation transmission is greater than currently thought, the current triaging system of respirators may result in HMG PPE guidance indicating a less effective form of RPE in a higher-than-expected risk setting.’

'In summary, antibodies against N protein of SARS-CoV-2 WERE NOT DETECTED in 408 (56%) of health care workers of a major hospital for COVID-19 in southern Vietnam.'

A huge contrast with the UK position: why?
@mancunianmedic @microlabdoc @mjb302 @DrLindaDykes @chrismainey @theRCN Image
Contributing factors?

1. 'Early preparedness and experience gained from previous pandemics...safety training on COVID-19 patient management and laboratory safety for its designated staff in early January 2020'

When did you receive your COVID19 safety training?
@davidshukmanbbc Image
2. 'To further reduce the risk of nosocomial infection, wearing a medical mask is mandatory for all COVID-19 patients, while being hospitalized.'

Are all your patients required to wear a medical mask throughout their in-patient stay?

What were you 'debating' on twitter on 21st April, 18:12 @trishgreenhalgh (your easy timeline search: 'skeptics' 🙂)? @AgnesAyton @mgtmccartney @jeremyphoward Image
I hope that's given you something interesting to consider. 🙏

Depressingly predictable, but with a twist 🙂:

'Dr Yvonne Doyle, Medical Director at PHE, said: “NHS 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?

@medrxivpreprint preprints since Jan provided multi-nation data allowing modelling of the UK peak casualty time point occurring w/o appropriate preemptive quarantine.

• Health services will be rapidly overwhelmed.
• Critical Care bed numbers would need to double within 1-2 days.
• Peak likely within 50 days of UK entry
