WEEKLY RESPIRATORY PATHOGENS SURVEILLANCE REPORT
This report is based on data collected up to 3 December 2022 (week 48 of 2022).
- The 2022 influenza season started in week 17 (week starting 25 April 2022), and ended in week 42 (week starting 16 October) when the influenza detection rate in the pneumonia surveillance programme dropped below 10% and remained below the seasonal threshold for at least two weeks.
- In 2022 to date, we detected 111 cases of Bordetella pertussis; 81% (83) from Western Cape, 12% (13) from Mpumalanga, 5% (5) from Gauteng, 4% (4) from KwaZulu-Natal and 2% (2) from North West provinces.
- In 2022 to date, a total of 856 COVID-19 cases were detected from all surveillance programmes. Of the 409 hospitalised cases, with available data on outcome, 7% (30) died. Since week 32 of 2022, COVID-19 cases have remained relatively stable in ILI and pneumonia surveillance programmes. Although the detection rate in the viral watch surveillance programme remains high (19-37%) in weeks 43 through 46, the number of samples submitted is low.
