Sorry to hear about your personal situation, I hope the lock down is not too much longer. Is the situation on the rock more like Spain or the UK? I mean in regards to the Supermarkets and panic that seems to be in the UK but Spain, at least where I am is fairly calm and supermarkets are well stocked and people are considerate. Compared to the UK where I witnessed a punch up over 12 bog rolls.
Who's goning to say who is the most vunerable? A 94 YO in Spain just recovered and our 55 YO PM is now going through a similar battle. The Antibody passport is a good idea but how far away is that?
Anyway, in regards to what testing can clear up. We already have a 10,000 strong case study that is South Korea. Every arrival has a 4 stage test, constant random testing in all accross the country, and contact tracing, asymtomatic or not. New cases are isolated and contained. The active cases is failing every day, which proves they are on top of the situation. Not sure of their critical care situation, but as they suffered a MERS outbreak in 2015 it's assumed they have been prepared for a while. The death figures will be skewed because of the aging population though, which should be taken into account in the final mortality rate. Japan is similar.
Korea, South
Confirmed: 10,331
Deaths: 192
Recovered: 6,694
Existing: 3,445
1.89% current death rate
Japan
Confirmed: 3,906
Deaths: 92
Recovered: 592
Existing: 3,222
2.45% current death rate
1 country closer to Europe that had the lowest death rate of any large sample is Israel, with many existing cases expect the death rate to rise.
Israel
Confirmed: 9,006
Deaths: 59
Recovered: 585
Existing: 8,362
0.65% current Death rate.
The mortality rate estimates have not changed, it's 1%.
People saying otherwise are generally news outlets that are concerned about the economy and want to downplay the situation.
This is not seasonal Flu
