A) Sample timeline of samples analysed for SARS-CoV-2, with positive samples shown in red. B) The percentage of sample detections that were positive for SARS-CoV-2 RNA (black line with grey fill) for the previous 7 days (left y axis) and the GC of RNA/100 mL (yellow, plotted to right y axis) for the previous 7 days. C) Cases of COVID-19 per day in the Brisbane North and Brisbane South Hospital and Health Service (HHS) districts (stacked barplot, left y axis), as well as the number of active cases (line graph, right y axis).
