SA's Covid-19 reproductive number is down to 1.1, says the National Institute for Communicable Diseases.
The number — commonly known simply as R — is the average number of secondary infections produced by a typical case of an infection in a population where everyone is susceptible.
The red line shows the decline of the Covid-19 reproductive number since SA's first mortality on March 27. The shaded area represents a 95% confidence interval.“This indicates ongoing transmission at a steadily slowing rate over this period,” said the NICD in its first report about SA's R since June 12.
The NICD said it had changed its method of calculating R since its previous report, which used data on laboratory-confirmed Covid-19 cases. The new estimates are based on lab-confirmed Covid-19 deaths. However, the new R estimate used data available until July 26 which were adjusted for the delay between the onset of illness and death, then “right-censored” backwards for 21 days to account for reporting delays.
