So, on the 15th 611,437 PCR tests conducted. On the 17th 620,291, only 523k, 564k on the 19th, numbers have generally been down on weekends, and sat/sun still well up on the previous sat/sun. So we still have a big increase in testing, and still have the biggest day being after the 15th
peridito but some testing is much less discretionary than others, and surely you'd have different behaviour by age if it was purely to avoid isolation?
So Pillar 1 are not discretionary, and we do see a drop in these!! but then that is to be expected as elective admissions are wound down for Christmas / in anticipation of covid cases. No massive change in positivity, which is what you'd expect if cases were really much higher due to lack of testing elsewhere.
Pillar 2 still running well in excess of any previous period other than early march (anyone know why there were so many then?) 50%+ above early December.
