The start of the 5th wave

The start of the 5th wave of COVID-19 infections can be seen when plotting positive test results. Test positivity has jumped to almost 20% in the four days ending 27 April 2022. The graph below plots a 4-day moving average of the ratio of new confirmed cases over new tests conducted as reported by the National Institute for Communicable Diseases (NICD). 


The uptick of new confirmed COVID-19 infections is lagging slightly the uptick in the positive test percentages. The graph below plots a 4-day moving average of new confirmed cases.


While there is little doubt that we will experience a 5th wave of infections, the disease severity caused by the infections will be key and must be monitored closely.

Time to consider the 4th wave?

Image
We have updated the NMG model to consider various scenarios for the 4th wave of COVID-19 infections for South Africa. You can access the model at  https://nmg-covid-19.sctechnology.co.za/ It will take a sustained viral propagation above a threshold speed to generate a noticeable 4th wave. The first 4th wave scenario is displayed below assuming a viral propagation speed of Rt = 3.0 for a period of 100 days starting on 15 October 2021.  The second scenario shows the impact of a viral propagation speed of Rt = 4.0 for the 4th wave. It is important to note that to reach Rt = 4.0 in the current South African population would require a viral strain with a basic reproduction number of over 12 (some four times the speed of the original SARS-CoV-2 virus). This calculation is based on the NMG model, where some 67.5% of the South African population is assumed to have built up immunity to reinfection due to infection over the first three waves.  A material 4th wave could be caused by a viral strai

4th Wave profile is emerging

Image
With the weekly new COVID-19 infections having peaked on 15 December, we are now in a position to understand the severity profile of the 4th wave. The good news is that the 4th wave disease severity as measure in terms of hospital admissions is 2/3rd of that experienced in the 3rd wave. The 4th wave disease severity as measured in terms of reported deaths is only 15% of that experienced in the 3rd wave. Weekly COVID-19 hospital admissions reached a peak some 12 days after the peak in infections at a level of 2/3rds of the 3rd wave peak. The new COVID-19 weekly deaths show signs of having peaked but only at a level equivalent to the weekly deaths experience between the 2nd and 3rd waves. Reporting delays may well be distorting these results! 4 January 2022

COVID-19 death toll increases in Gauteng

Image
The third wave shows no sign yet of reaching a peak in Gauteng and, equally as worrying, the reported COVID-19 deaths have gone past the second-wave peak in this province. The gradient of the third wave in the Western Cape would appear to indicate that the Delta variant has not yet spread beyond Gauteng. Reported COVID-19 deaths have gone past the second-wave peak in Gauteng which is of concern Reported COVID-19 hospital admissions in Gauteng are showing signs of plateauing at a level equivalent to the second-wave peak in that province. This is almost certainly due to having reached hospital capacity. 7 July 2021
