"Much of my wider family has had Covid, some more than once, one lost their life. But my immediate family, mum, dad & sister, have not had it at all. They are active, out & about, at work etc, my sister even goes to concerts. The one difference is they didn’t stop wearing masks."
Not so sure about the mask situation they are still wearing them in NZ and my son said it s surging through they ve all been free since start now all gone down with it including in laws whose company they haven’t been in and clients the grandkids etc etc The Chinese wore them long before CoviD but the country has been overrun with the virus So I m not convinced at all
Chinese and other east Asians wore masks for particulate pollution before covid. Used that way they are useful because the particles (e.g. sooty smuts) are huge compared to the microscopic aerosols that spread covid around and which can get round and even through most of the face coverings that have been used during the pandemic.
