First of all, thanks for posting that article. It made for interesting reading.
Personally, I just don't think imposing a national lockdown for so long is a practical proposition. Will people wear it if they haven't tested positive, no one they know has tested positive and they're not in the high-risk category? What if they need a plumber? An exterminator? An electrician? What happens when they start running low on food, especially fresh food? Six weeks on canned goods (if you can store that much) with no exercise and little sunlight could lead to a whole
new health crisis. Can people living in flats hold out that long? Even prisoners in solitary confinement get an hour in the exercise yard every day.
I would also add that I just don't trust any figures coming out of China, and I just can't believe that businesses around the world could be so gullible as to accept that it's going to be business as usual already.
I note the South Korean approach here which instead of locking down everyone, just locks down and tracks people who have already tested positive or been in contact with people who have. It seems that the approach they're taking there is basically the approach we're taking here, only they're doing it much better. I think the gathering limits, closing the borders etc that we've put in place all make sense but it's a bit of a worry that we apparently don't have the resources to ensure that people who've been ordered to self-isolate are actually doing it.
Now that's all been said, I'm not an epidemiologist (either a real one or the other kind) and this is probably a good a time as any to post this:
