So despite a 2 week lockdown, their gold standard contact tracing still has not got all primary and secondary contacts in isolation?? So they are happy that 13 cases were in isolation, great, what about the 7 that were notified part way through, and 7 that presumably were not even notified by contact tracers to isolate. If thats the case, then the week extension will not be enough.
I know people have bagged our Victorias contact tracers, but correct me if I'm wrong, but after a week of lockdown this last time, we perhaps had 1 or 2 per day (some days with none) that were not already in isolation. 2 weeks down and Sydney are still having significant numbers that contact tracers haven't got to.
