Well we can opt to start practising now, with the weather on our side for months ahead, or, possibly, let SARS-CoV-2 force us into lockdowns again next winter when we’re all indoors breathing each other’s air… Eggs and baskets.
But I agree, it’s unlikely that our highly advanced governments would try anything so cheap, safe and reliable when they haven’t even encouraged us to open windows.
Places that enforce a zero infection rate require the shortest periods in strict lockdown; just the few days it takes to trace a handful of infections. People and businesses withstand such short stoppages far better than prolonged weeks in semi-lockdown. Long term, if vaccination turns out not so great, places pursuing zero covid will enjoy economic advantages, and as green zones proliferate red zones will suffer increasing exclusion.
