No, because that's not what I claimed and I'm not your Google monkey.IT minion. Could you list the “most other countries “ with effective track & trace please?
Not just one Or two, you stated most other countries. I expect you’ll provide lowering rates of infection as evidence.
I said as far as I know other countries test contacts of positive cases. I believe China and South Korea did, I know New Zealand did. All three have had effective track and trace efforts. Not all perfect, but as I said it doesn't need to be perfect.
