Masks can never be a cure, but they do help prevent transmission, and protect you from others. My son and family live in Japan and the whole population wear masks to help prevent transmission - and did so pre- covid - with great results.
I can never understand why people won’t wear them to protect others. Just selfish!
There was some research that initially stated they made no difference, but science soon proved them wrong and the opinions were changed. Obviously a few of you never caught up with that.
I hate wearing a mask as I have asthma and other issues, I am also in and out of hospital quite frequently for day surgery, and I am so very glad of all the care taken to protect others.
I still wear one and will continue to do so.
