I remained amazed by the certainty so many people seem to have about the best approach to tackling coronavirus.

I think we can say suppression has been necessary to protect the NHS. But it& #39;s not at all clear what the right exit strategy is going to be.

There seems to be real disagreement amongst experts as to whether "test and trace" is viable in a liberal democracy (i.e. not China) that& #39;s already experienced mass transmission (i.e. not South Korea).

Lifting and then reintroducing lockdowns when a trigger is hit seems another (or perhaps complementary) approach but I have no idea how that works in practice. Can businesses operate w/ that level of uncertainty?

And then there& #39;s the option of serological tests leading to "immunity certificates" that allow some people to operate as normal. There are some fairly obvious ethical and behavioural issues with that idea.

I don& #39;t think anyone has the answer to these questions yet - which doesn& #39;t mean we shouldn& #39;t ask them. But the certainty some non-experts have is remarkable!
