Get a Grip people!!
July 24 202 the Govt mandated mask use. Clearly that has not worked given the advent of the 'second wave', the Tier systems response to rising rates, the 'Circuit Breaker' lockdown and the latest national lockdown (all the while allowing foreign travellers in the thousands in via the airports)
The masks that the vast majority of the public are wearing do not work to prevent transmission of the airborne virion particles, which are of the order of NANOmetres in size - and according to press reports around a year ago can "hang around in the air for up to 3 hours".
They are not made to any declared quality standard
There is no information on the materials used, condition of manufacture etc
There is no information on shelf life
There is no information on service life
There is no information on disposal instructions
There is no information on minimum mesh size and the declared size of particle expected to be filtered
There are gaps to the sides, top and bottom, they are not fitted to the wearer with a skin tight seal
Wearers are not following protocol of use by not touching, allowing them to slip down etc
Multiple use is clearly practiced with people putting them in their pockets
There is no information on any pressure influence through the material due to exhalation and stretching or 'pushing' of virions though the material
There is no information on pressure drop due to inhalation and the any deformation of the mesh / material as exhalation begins
There is no information on expected fill rate & efficiency of the mesh ie: how quickly the mesh / pores become blocked due to exhalation moisture and / or saliva if expelled
etc etc etc
Unlike surgical masks which are used by surgeons in a sterile environment, put on by surgeons with already scrubbed disinfected hands and surgical clothing, gloves, hat etc on and which are used, often as a further (hopefully redundant) risk reduction measure to mitigate the failure of other sanitising processes & equipment - they are intended to stop gross particles of facial skin, hair, sweat, spit etc from entering an OPEN wound and causing an infection. They do not stop the surgeons breath from entering the room nor being around the patient as they operate over the patient.
So, put your rational heads on and critique the 'Pots & Pans For Spitfires' panacea that this government has conned everyone into buying so that they can continue to allow huge corporations to keep making money and people buying their sh1te. We have been sold so many lies around this pandemic that people need to stop taking anything they say as having any semblance of veracity.
Its Weapons Of Mass Distraction, sold to you by the very same people as before...
