I would like to see the results of research (must be some of decent quality) on mask wearing/contamination when worn over a long period, i.e. a working day. Would masks need changing frequently? Would workers comply? Would this affect our immune systems?
I am very much pro-mask in our Covid time but again and again see people with masks under their noses, only mouths are covered and I have seen one hospital nurse wearing her mask like this! Employees may not be happy at masks being made mandatory.
Personally, I would have three or more chest infections between October and March, sometimes more but last winter, not one. Yes, I didn't socialise or use public transport but was out and about and through necessity in and out of hospitals/GP surgeries and not one sniffle did I have.
I will continue wearing masks in the future when outside my house and mixing with large groups of people. Seems sensible to me in my circumstance. Whether this latches on to the public's psyche, I don't know but would hope so.
If I were a food-handler, I presume that if presented with the choice of wearing a mask or no job, I guess I would choose the former and in time perhaps this would become the norm.
