No amount of 'understanding the rules' is going to help us out of this one because the rules aren't adequate. Without a rigorous test, track, trace and isolate regime in place, with financial support for people who have to isolate, the virus will continue to spread.
The TTI operation 'lost' 16,000 people who had tested positive not so long ago. That's 16,000 potential spreaders of the virus who, despite frantic belated efforts to trace their contacts, had time to infect thousands more people who, in their turn could have infected thousands more. All because the 'world beating' privatised system was so incompetent that it was using obsolete software to transfer positive test results to the track and tracing operation.
Meanwhile, local authorities which have used their public health infrastructure to track and trace have done a far better job while working on a shoestring budget.
Coastiepostie is spot on in their analysis. Elect an incompetent, fantasist, lying charlatan as PM and this is the result. Chaos and incompetence.
