As you can see, currently in South Africa – and many of the provinces – the number of new cases is showing a decreasing trend. However, it is questionable if this decrease is as large as it looks like, as there is a huge decrease in the number of tests. In the week ending on 1 August, almost 43 000 fewer tests results were reported compared to the week ending 18 July which amounts to about 11 000 fewer new cases reported (using the average test positivity rate of the week ending on 1 August). In general, 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 (due to being asymptomatic, limiting tests to certain patient groups due to shortage of test kits, reagents and laboratory capacity), so the actual number of cases is probably higher.
A more reliable indicator of the progress of the epidemic at this point might be the number of people who die of COVID-19. However, the reported number of deaths linked to Covid-19 in South Africa is much lower than the recorded "excess deaths" in the country. [samrc.ac.za/reports/report-weekly-deaths-south-africa] Tracking excess mortality is widely seen as way to gauge the full scale of fatalities from Covid-19 as it e.g. includes those suspected of having the coronavirus who died without having been tested.
