It’s not shops spreading covid or garden centres or people going on walks........
It’s also largely not down to offices or workplaces or even pubs and restaurants.
Two things :
Schools because children are known infection vectors
And people visiting friends and family
If the government said we’ll keep open the economy but you can’t see your friends and family in private settings then it would probably have a bigger effect
Sadly the latter is impossible to police and you get people saying “why can I go to the pub but not see my mother in her house”
And it’s because friends and family do not socially distance when there is not someone making them. At least in public there are monitors to come extent in the form of external people and staff.
It’s people like my 76 year old mum giving her friend a lift to the supermarket once a week so they are in the same car for over half an hour
Or having my aunt and uncle over to visit - well we sit on separate chairs - yes, in a small living room with the windows closed because you are old and feel cold
Or my friends kids running up to give us a hug when we pass them on the street.
Closing the economy down is a smoke screen because what actually needs to be done is impossible to police
