With regard to the question of should we have locked down earlier.
I have a simple answer, YES we should have locked down earlier.
When we delayed the lock down we were doubling the number of cases every 3 days.
Post peak, I believe we are now halving the number of cases every 12 days.
That means for every 3 day delay to lock down, one has to then remain locked down for an extra 12 days. So a week delay to lock down equals an extra 4 weeks of lock down. And so on.
The experts should have known this, and this should have been the argument for early lock down at government level. This should have been the end of the argument, sadly it was not 🙁
From both a health and economic perspective an earlier lock down would have been better.
