We're ALL going into at least a month's quarantine here in NZ in 24 hrs - the government hasn't just sprung it on us, they've worked up to it over the past few weeks, they started putting people coming from some countries (China, Iran, Italy) into 2 weeks isolation, then everyone entering, now we're putting the entire country into at least a month's isolation.
At the same time they've been making changes to support people who's jobs are going away (tourism is big, it's collapsed) and to keep businesses running (last week), mortgage holidays (today).
It's not going to be easy, there's going to at least be a recession, and we're likely to be cut off in some form for far longer than a month.
So yes you can do what China and other Asian countries have done in the West, but you do need real leaders capable of framing an issue so that the whole society can get behind it
