China did a quarantine for around 4-6 weeks and locked down wuhan. It’ll be interesting to see what happens next there.
It’s not pointless doing it for a few months because you can flatten the curve. We may have to do it again and we may not, maybe things can be relaxed soon and maybe not.
It’s not like it stops everyone working anyway. Everyone I know is working as normal from home for now.
Either way it’s better than the situation in Italy and Spain.
