New COVID-19 Cases per week in South Africa
As an epidemiologist, I want to see if the number of new cases of COVID-19 is increasing, stable or decreasing over time. This in order for me to know if things are getting worse or better and based on that to determine my behaviour. So until the 1st of August 2020 I visualized the weekly number of new cases in the country and each of the provinces.
Later on I moved to displaying the number of new cases with the number of new tests reported, and reporting the positivity rate (currently 4,5%). One must keep in mind that this graph only shows the number of confirmed cases, so excludes everyone else who may have been infected but was not tested.
