It's not as straightforward as that.
South Korea and China were forced into a total lockdown. Italy too. They were ascending the peak. A strategic choice was taken out of their hands.
The Chief Scientific Adviser to the government was very honest yesterday.
There are two choices. You do what South Korea and China have done or you immunise the population by controlling the infection to last as long as possible at a reduced rate of transmission.
If you suppress something very hard, when you release those measures it bounces back at the wrong time so our aim is to try and reduce the peak, broaden the peak, not to suppress it completely. So because most people get a mild illness, to build up some degree of herd immunity as well, so that more people are immune to this disease and we reduce the transmission, at the same we protect those who are most vulnerable.
However, China's strategy seems to have worked. It has not yet bounced back.
It is very tempting to see that evidence and just say shut social contact down for a month, and then emerge into a Covid19 free world. Of course it will still be there in tiny numbers but I think with every day that passes, and China improves, then this really seems like the way to go. We will probably be forced into it soon. When you go from 500 to 1000, then 2000, 4000 you really have little choice anyway. That's what happened in Italy. they were forced to respond and had no alternative. The same thing will happen here.
