Ballsy call by Sweden's politcal/healthcare leaders, pretty much exact opposite of New Zealand. Sweden chose a pragmatic, practical approach. Basically saying to its citizens ; be responsible rather than mandate this responsibility. An important distinction. Quarantine is for the sick, high risk. If there is a second wave, i'd imagine they'd handle it better than other countries. With that said, New Zealand shut her all down real early and it appears is ready to open soon with a pretty clean health report card , no idea of the damage to its economy.
The idea of the shutdown in N America was designed to not overwhelm healthcare (unfortunately happened in New York), it wasnt designed to prevent the population from getting the virus. If we are waiting on a vaccine before opening up? pipe dream. If the epidemiologists r going to trace, test, track with efficiency they should have done it by now, they havent, hence likely not a practical option..
The clock is ticking on the N American economy.....
