  • Google and Apple teamed up to provide a shared platform to track the spread of Covid-19 around the world, called COVID-19 Exposure Logging.
  • The Department of Health's COVID-19 Alert app makes use of this platform to implement a track and tracing solution.
  • Via Bluetooth, the app will alert you if you have passed someone that had Covid-19 in the last 14 days.
  • All data is anonymously collected, processed and stored. You are identified only with a unique identifier on the platform.
  • With experience in data security, the author of this website cannot endorse a better solution!
To find out how fast Covid-19 is spreading, we can calculate the Effective Reproduction Number (Rt) as the pandemic progresses. This number tells us, on average, how many people each infected person is likely to infect.
For as long as Rt is above 1, the virus is spreading rapidly. The challenge is to get Rt below 1 to stop the spread.
This website provides up to date Rt charts for the country, provinces, districts and subdistricts (where data is available). Only areas with significant spreading will be shown.

With enough applied knowledge we can beat the virus!

The latest Rt value for the country is 0.87, last calculated on 04 March 2021. This means that each newly infected person is likely to infect 0.87 more people.

The following assumptions were applied to calculate the trends

  1. Where testing data is available, an advanced multi-variable model can be used.
  2. Applies to South Africa country Rt plot.
  3. Testing and case data are the two input dimensions for the model.
  4. Considering 10 days for the virus to incubate, all case data are back-dated.
  5. The error bands indicate the 80% credibility interval.
  6. Forecasted plots will use the latest calculated Rt from this model.
