I would re open the nightingale hospitals.
Make them dedicated covid treatment centres.
Rest of hospitals and NHS services back to normal, start providing all elective surgery and cancer treatment etc.
Clear criteria for who is at risk.. And they can choose to shield, isolate etc with government backed delivery slots for food, medicines, etc.
Anyone in above category has to be allowed to wfh or their wages paid by government. So not financially damaged.
Everyone else back to work, play, sport.
With requirement for sensible precautions.
Table service in restaurants, etc.
Basically the Swedish model with increased support for people who are vulnerable but give population some self responsibility.
If your elderly you are capable of choosing not to see your family etc.
I would also immediately start a national support phone service.. A register of everyone isolating and they would get a daily call for chat, check in, make sure they have food, medicines etc. Company etc.
I'd also provide national pet service so isolating elderly can have their dogs walked etc.
I'd stop the scare mongering.. 50000 cases.. Yes but the majority of you will get better.. If you get ill at all.
We cannot control this.. We can keep a lid on things but as soon as you move the lid an inch it will be put like the genie out of the bottle...
Those citing nz.. Well yep but as soon as they open borders, they will be back with virus in their midst.. What then... Isolate the whole country for years?
