I think 'lockdown' is seen as some sort of panacea on here. It will not get rid of the virus.
We should instead be looking to the example of South Korea and rapidly expanding our testing capacity, so we can isolate those infected and their contacts.
A lock down is a short-term populist solution to a crisis that is going to be with us for 18 months.
In South Korea, schools are open, bars are open and shops are open.
