What coronavirus rate per 100,000 people is safe enough / manageable?

[MRex]

What rate (per 100,000 people) of new daily coronavirus cases seems to be manageable enough to keep things open while staying on top of cases? We aren't a NZ who can close our borders for long without major business impact, so elimination however desirable is a distant dream. Meanwhile people want schools open, pubs open, shops etc and the disruption of open/close is very undesirable. So what is an acceptable rate/100,000 people that the UK can cope with for now in each region? And why do you think that level is manageable? And does the level differ per region?

It might be useful then when we look at local area figures to internally say "ah, we keep on top of anything under 2/5/10/20 per 100,000, low enough risk for shielded, so that level is ok." I'd be interested in getting everyone's thoughts please. (Particularly from the data thread, but anyone.)

It's interesting that everyone so far has quite low rates, whereas there are descriptions of people carryimg on as normal in some areas that have restrictions and far more cases.

Well I guess that explains why cases are high!

Everyone is flooding the rules here on the whole. That's when risk is so low atm based on our cases.

But if you have high cases and aren't following them then a) it may explain how cases rose in the first place and b) wouldn't support a quicker drop in cases.

If the whole point (supposedly) was to protect the NHS, wouldn't 'acceptable levels' per area need to be based on what maximum capacity for treatment in the area is?

Does the UK government have a number that they work to?

My area is 758/100,000
That seems very high!

Oops, that's the total number of cases.
Where do I find daily cases in my area per 100,000?
