In terms of our contact tracing indicators, I would point out that one of the reasons Dr Verrall and I have been actively discussing this is the original indicators were based on the notion that there could be 15 to 20 contacts per COVID-19 case. In this particular case we have now contact traced 2,609 potential close or casual contacts for one single case. That is not what the performance metrics were designed to be based on when that report was first adopted.
