I suggest people have a read of this NZ article. https://www.interest.co.nz/opinion/104193/notion-new-zealand-running-ahead-curve-no-longer-stands-scrutiny-policy-essentially
It makes interesting reading. It s all about the government needing to be Proactive rather than reactive , and discusses Professor Michael Baker from the Wellington Campus of Otago Medical School who has spoken publicly in recent weeks about his concerns. IMO we need to 'stamp it out' and not just flatten the curve. Because flattening the curve is going down the route of herd immunity where over a very long time, a significant percentage of people get it, but it doesn't put major pressure on our health system, so it should result in less deaths. Stamping it out is about actually getting rid of the virus totally, by starving it of people to infect, which allows NZ local population economy to get back to normal potentially earlier. It appears stamping it out is the only way to prevent older people not being told to 'stay at home' for months and months while he virus exists. I am not sure exactly what China are doing to reduce their rates, but but guessing it is more of the 'stamp it out' thing.
