None of which is relevant to the issue of testing.

I don't like that, but it is rational.
It sounds rational, but the devil is in the details. What does it
The one where the UK is getting it totally wrong at the moment is that
they have said any family member with symptoms entire family must self
isolate. This sounds OK at first glance *BUT* many medics marry other
medics so you lose two trained staff each time one of them gets sick and
if they do have coronavirus you really need to test for it.

People that have recovered no longer need full PPE since ordinary
barrier nursing will be sufficient protection for them and I strongly
suspect that running out of PPE mid-pandemic will be the next disaster.
mean exactly "might change subsequent actions"? Anyone who tests
positive will be treated for the disease even if this only means self
quarantine at home. But if many are not tested, many infected won't
know to be quarantined.
There is no realistic treatment for the disease beyond helping people to
cope with the symptoms and oxygenation or ventilation if they are unable
to breathe. UK only has about 5000 ventilators and the health minister
has been asking JCB if they could knock some up on their heavy tractor
production line (they mostly make quarry trucks and earth movers).
