A NZ professor said it might be gone in 14 days. If that did happen, Im sure we could confirm that before 2022. I feel we can may start considering that before 2020 is out, although, it would largely be case free before that. My opinion
Covid-19 is a global issue. We cannot say we are in clear until we have a treatment, vaccine and the spread globally under control. If it becomes endemic then we have a whole different scenario. Having no new cases in NZ in say two weeks while excellent is only one small step. To quote Winston Churchill
"this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning". I believe that 2022/23 is a reasonable time frame to reach a point where we can let our guard down.
