Covid-19 Tests, Cases and Positivity Rate: Updated Daily
This post will be regularly updated with data on the recent Covid-19 outbreak in Australia mapped against the earlier outbreaks.
Last Updated: 2021-01-19
Methodology
To produce these plots, I have mapped the current outbreaks in NSW and VIC against the three recent outbreaks with significant community transmission: 1) NSW back in July, 2) VIC back in June, and 3) SA back in November.
As a result, the x-axis in these plots does not show “Date” but instead it is the number of days since the first case of outbreak was reported. I have also added a week of observations from the period before each outbreak so you can better follow the impact of each outbreak on the trends.
You can remove a specific state from the plot by clicking on their name in the legend area. You can also save the plot as an image or download the data using the icon at the top right corner of the plot.
Covid-19 Testing Patterns
The first plot shows the number of tests per 1M of population in each outbreak.
Covid-19 Cases after removing HQ
The second plot shows the number of cases but only includes the cases of community transmission.
Covid-19 Positivity Rate after removing HQ
The last plot presents the positivity rate which is based on the number of positive tests (daily cases) out of total tests reported on each day.
Cumulative Covid-19 Positivity Rate after removing HQ
For this chart, I have calculated the daily positivity rate by dividing the total cases reported since the first case was reported by the total number of tests done during that period of time.
