Masks are really for one thing and thats to keep particles of whatever out of the circulatory system.
One sneeze from a person who is A symptomatic and doesn't know he has the virus (just like a flu) and you gobbl;e it down unknowingly as it floats around..........and bang you too are a statistic.
So in many environments such as close quarter, its ALWAYS a good idea, buses/tubes/shops.
We are in the UKmaking it compulsory to wear masks inside ALL retail shops from next week.
My take on it all is, we need to be practising all of this as winter approaches, and I think the normal 600,000 flu deaths each year here can be reduced if we always wear the masks.
There are always those out there like Trump who think a mask is a waste of time......as his closest aids go down with the virus. See he had his first press conference wearing one.......now thats eating humble pie, and backing down on how dangerous it really is!!![]()
