Thanks.
so maybe 500 daily deaths is your benchmark.
That's just two doublings from where we are now. Cases in Scotland doubled in just the last week. So, given return of schools etc, it's far from inconceivable your scenario does indeed pan out, and fast. So we should be prepared for it.
As to what I would suggest - well, I'm no expert in this, but I think we should prioritise things which are low impact. For instance
1. Vaccinate adolescents.
2. Major vaccine drive to get the adult unprotected covered as far as possible. Vaccine passports as per France might be an option.
(both of these regardless of cases)
If cases rise towards levels we expect to give problematic deaths and hospitalisations, then low impact restrictions such as:
3. Masks in crowded indoor settings (public transport etc)
4. Support people to isolate if positive, expand testing
5. Reimpose home working unless imperative to be at work
And if that doesn't work,
5. Limit mass gatherings (sorry blues, religious types)
6. Hospitality limitations (table service and whatnot)
Schools would be my last resort.
You might have a different list, in a different order, but increasing immunity, decreasing aerosols and limiting interactions is where we'll be at.
It might be, as we seem to have seen at "Freedom day" that when people are concerned about the virus, they self limit their behaviour. But just crossing our fingers and hoping doesn't seem like a good plan to me.
