When I read all of the above and then go out for a walk, before daylight, I can see why the infection rate is high.
I see buses in West London, noticeably the 140 heading for Heathrow full of workers, with very few wearing masks, especially upstairs, and most of the bus windows shut. Later on I see customers entering supermarkets and about a third still maskless and another smaller percentage wearing them as chin warmers or an exposed nose.
They just don't care or understand.
Then children pick up asymptomatic from parents of the above don't care mob, pass it around school which then gets taken home.
Very difficult to stop transmission.
