We will never be able to reduce the total cases, but we can aim to reduce the number of active cases in South Africa.
Active cases can be calculated as: Total - Deaths - Recovered
Simple? Well, official numbers for "recoveries" jumps up in big steps every few days: 0, 31, 45, 410, 903, 1055. Is this realistic? Probably not. In turn, this leads a very volatile calculation of historical active cases.
What's the work-around? What we can do is infer data point between these "steps" in the recovery data using linear interpolation. And from there we can plot a more realistic history of active cases.
