About that damned nebuliser:

National guidelines don’t even regard nebulisation as an aerosol generating procedure. In fact linked documents say the reason to avoid it is that it encourages coughing. 1/3
My point is that non-nebulised, original strain SARSCOV2 is contagious enough to warrant airborne precautions, ventilation studies, engineering controls, auditing, and aggressive isolation in high risk settings such HQ. The neb is relevant but focus on it is excessive. 2/3
The bigger picture is that along, experts have minimised the airborne and aerosol transmission potential of this virus. And this attitude flows from the top - ICEG and federal CMOs.

Here is an example of that denial from experts who are now attempting to revise history. 3/3 https://twitter.com/drvyom/status/1359425766178443265
This is an expert from ICEG who within the last week has flipped from saying REPEATEDLY that Covid is not airborne to now saying ‘I’ve said it’s airborne’ - Something I have predicted many months ago.
Ex Deputy CMO has also played word games with the terms aerosol/airborne. 4/3
In summary -

Is the nebuliser relevant? Yes.
Is it plausible that it caused a transmission that would not have occurred otherwise? I’m not convinced, but not implausible.

But A LOT of other dominoes need to topple for a nebuliser to culminate in a 5 day lockdown. (5/3)
Oh - similar argument for the UK variant. It is relevant to the management of the outbreak, certainly the decision to lock down, but does not vindicate the systems that lead to the breach. (6/3 I’m done for real)
