Are all old folks in homes Jem? Just start there and you will see. What everyone else did was belt and braces, lock down the homes, lock down outside interaction of the staff/guests/suppliers who were the ones bringing it in. Sure there were some cases present but there were also staff with no PPE.
The less wild spread you have, the less chance the staff/suppliers bring it in. Staff do drills, learn (slowly, takes time for form habits) management identify and remove the utterly hopeless (there always are), PPE is perfected, etc etc.
Many died in Sweden because of a culture of not transferring elderly to hospital and putting them on palliative care when they had a fair chance with intensive. Learning not to do that took time.
Now, what about everyone else? Not in homes but dying at home and of course the much of the younger pop with some pre-existing.
Stop for a moment and outline how with people moving and a virus hitting 100k a day and more new cases real fast you could have protected them.
Serious, if you are the brain you believe you are that should be easy.
