Thanks for the link.
The information in that paper is clearly logical.

The following is a quote from the paper:

"A lockdown is a temporary measure which if done simultaneously and completely will result in reduction of epidemic size, more manageable case numbers and a flattening of the curve so that health system capacity is not exceeded. China has shown that a short lockdown can be highly effective and can be relaxed safely in a phased manner. The only two countries to achieve flattening of the curve to date are South Korea and China. South Korea has achieved this with more targeted, short lockdowns but extensive testing. In countries that have restricted testing, used slow trickle measures and avoided lockdowns until late, such as Italy, Spain and the US, we seen failures in epidemic control."
