//NJ, its not the "amateur" face covering, its the "amateur" user.//
Of course it is, woofy. Because we’re all (well, 99% of us) amateur users. Your regime seems admirable. Not one I would be prepared to undertake if I wore a face covering for no other reason than I rarely go shopping in my car. Carrying a supply of spare scarves around with me, together with sanitisation paraphernalia, then finding somewhere to do all that is not something I would be willing or able to do on foot or on a bus or train. But the government has issued no guidelines to educate people in the proper use of face coverings. And it doesn’t seem that even you know that any one covering should not be worn for more than 30 minutes before it should be changed.
//what wearer risk? If you cough or sneeze into a facecovering all that will be deposited is what came from you.//
Coughing or sneezing is not the risk (see my earlier posts).
//Your concern, I think, is that somebody who doesn't have Covid is more likely to catch it if they wear a mask. I think most people, including you, are not in a position to argue that one way or the other. It would all be guesswork, probably biased by the outcome they actually wanted. For example, you may well be more likely to catch Covid if you wear a mask and come into contact with Covid, but you may be less likely to come into contact with Covid in the first place if everybody wears masks. Most people don't have the time or resources to figure that out, so they leave it to the government and their scientists to do it for them.//
That isn’t the issue at all. The risk comes from “amateur” users. The use of PPE is a discipline that is instilled in medical professionals. It’s not a hobby that can be indulged in by amateurs. The increased risk – small that it is - to the user who fiddles with his mask (or other covering) between pawing through the baked beans in Tesco’s, getting on and off the bus, going for a coffee, going back into another shop and so on far outweighs any possible benefit to others. I made my decision a week or more ago and explained why. My cousin is the clinical nursing director (“Matron”) in a large hospital. She has spent >30 years working in operating theatres, A&Es and ICUs. She has forgotten more about PPE than most of us will ever know. She will not wear a face covering outside her hospital because even she, with her vast experience, does not trust herself to leave it alone when outside work. She has advised her husband and adult children likewise. Sometimes leaving the government and their advisors to figure things out for you is not the best strategy.
