Well with the situation we’re in, I’m more suggesting the opposite, where we actually need to be testing every single person in the country at least once a week. Like the Premier League us. Otherwise T&T will never keep up with the spread and all that money is wasted.
What should happen/should have happened, is an eye-wateringly strict lockdown as early as possible. Borders closed, stay at home (which really means stay at home), workplaces apart from essential produce shops all shut (no exceptions), no international sports or things like the CL, nobody moving around the world or even the country, and a T&T system then brought in to get a grip of who’s got the virus.
Then slowly open things up, after it appears the R is at ‘0’. But borders should still remain closed (like in Aus and NZ) for a long time after while the virus is still around the world.
The T&T system would then work.
It might be hindsight to say we should have done that from March last year, but we saw what happened in March and should have done it ahead of the Autumn rise and again before this Winter rise. We had a chance to learn from March and didn’t learn and didn’t do it either time we needed to subsequently from March.
