Socially isolating, self isolating etc
Given that the virus has been in the country for a few weeks now and that the children are still at school? Delivery drivers and postmen are still working too. Plenty of people can't afford to self isolate (a dinner lady can't work from home and probably can't live on SSP). People who receive home care cannot self isolate and nor can their carers. Many restaurants are starting to do takeaways for this first time too.
I'd imagine that most people will have been exposed to by now.
It almost feels like the gov just felt like they needed to be seen to be doing something, so issued some confusing guidance. And given by the amount of confused threads on here, it is confusing.
