Japan’s main method of halting the epidemic seems to be not testing many people, its not an approach many people feel is particularly well thought out.
that said, I do think that the approaches that countries like Singapore, South Korea, Taiwan and Hong Kong have taken are a good way forward, real changes but getting in early before it’s too late and before everything needs to be shut down. I’m hoping it isn’t to late that my country, Australia, to follow that approach, seems to me that the USA and Western Europe is probably too far gone for that now.
