On a panel & was asked if COVID-19 will help world prepare for the 'real' big one. I actually think SARS-CoV-2 is the big 'Disease X' experts warned about. We shouldn't underestimate the current crisis which has no simple solution.

If it were as lethal as MERS (33% CFR) then all gov'ts would aim to eliminate. If it had similar health outcomes to flu then gov'ts let it go. It falls in-between leading to muddled strategies, conflicted scientific advice & in the process, economy/health both taking a hit.

The challenge is to re-open economy/society while controlling COVID-19. Robust test/trace/isolate supported by face coverings, hygiene & border checks can help. But 'super-spreading' events still a big challenge. E.g. 91 people testing positive from night at club in Barcelona.

Some push for ‘shielding’ vulnerable groups & let virus run through rest. But: would mean shielding over 40s, those with health issues, those who are obese, ethnic minorities & other risk groups. Also can’t easily separate healthy & vulnerable. And no certainty over immunity.
