You won't like my answer @lljkk
It's short-term pain, long-term gain.
We have plenty of examples to follow. In fact I bet we could get an adviser from one of the countries who's successfully taken containment measures. For a cheaper rate than Dido Harding.
Restrictioms for approx 2 months. Possibly 3. That's only so long because we let things get so wildly out of control.
Perhaps just one month of the strictest measures - schools, non essential shops, bars, pubs, etc closed.
Slowly ease out. Start to open up but initially reduced hours. Borders shut excepting essential imports etc (proper quarantine where necessary).
Truly effective test, track, and trace? First, no excel spreadsheet cockups. Next, enough testing capacity, and test results within 24-48 hours. Like Italy, Germany, and much of Asia, test all contacts of positive individuals. Not just those with symptoms
We should've done all this in February or March. Or even over the summer. It would be over by now (border restrictions aside).
But we didn't. It won't just go away. The way things have been - this kind of shitty not really normal on off on off everywhere in the country has different confusing ever changing rules. Want that to contine for about a other year? If not, we have to be prepared for temporary tough action. It's worth it to avoid 12 more months of this (and to save the longer-term economy).
Unfortunately too few in England seem to realise this. (Scotland gets it, I think, and perhaps Wales too).
