COVID-19 SURVEILLANCE REPORTS
NATIONAL COVID-19 DAILY REPORT DASHBOARD
Please note that due to a technical problem, the reported number of new tests in the public sector for today includes tests from 25 May 2020 that were not reflected in yesterday’s report.
The purpose of this report is to project estimated COVID-19 cases at national and provincial.
The National COVID-19 Epi Model (NCEM) for the National and Provincial long-term projections released on the 6th May 2020 and the short-term projections released on the 12th of June 2020.
This report includes an analysis of data on laboratory-confirmed COVID-19 deaths to estimate the effective reproductive number (R) of SARS-CoV-2 over time in South Africa nationally and in selected provinces where sufficient data are available. The effective reproduction number (R) is the average number of secondary cases per infectious case in a population composed of both susceptible and nonsusceptible hosts (once the infectious agent is circulating). If R>1, the number of new cases per time unit will increase, such as at the start of an epidemic.
This report summarises data from national laboratory-based surveillance that is used to monitor the COVID-19 pandemic in South Africa. This report is based on data collected up to 12 September 2020 (week 37 of 2020).
-As of 12 September 2020, a total of 649 793 laboratory-confirmed COVID-19 cases had been detected in South Africa. The number of newly detected cases continue to decrease week on week, with number of new cases detected in week 37 (9 815) lower than the number of new cases detected in week 36 (11 942).
-In the past week, Gauteng Province reported the highest number of new cases (1 966/9 815, 20.0%), followed by Free State Province (1 851/9 815, 18.9%), and KwaZulu-Natal Province (1 321/9 815, 13.5%).
-Western Cape Province continued to report the highest cumulative incidence risk (1 584.3 cases per 100 000 persons). Free State Province (1 450.3 cases per 100 000 persons) replaced Gauteng Province (1 417.6 cases per 100 000 persons) as the province with 2nd highest cumulative incidence risk and the Northern Cape Province (1 059.6 cases per 100 000 persons) replaced KwaZulu-Natal (1 031.0 cases per 100 000 persons) as the province with the 4th highest cumulative incidence risk.
-Similar to the trend in the past three weeks, in the past week, Northern Cape Province (89.7 cases per 100 000 persons) followed by Free State Province (64.1 cases per 100 000 persons) and North West Province (23 cases per 100 000 persons) reported the highest weekly incidence risk. The weekly incidence risk in all the other provinces was less than 20 cases per 100 000 persons.
The report is based on data collected from 5 March to 13 September 2020 (week 37 of 2020).
-Numbers of respiratory hospitalisations continue to decline.
-The proportion of respiratory or COVID-19 hospitalisations in all ages is decreasing but remains at a very high level among individuals aged ≥20 years.
-Percentage of general practitioner and emergency department visits coded as respiratory is also declining.
-There has been a sustained moderate increase in RSV detection since week 29 (week ending 19 July) in the pneumonia surveillance programme and to a lesser extent in the Influenza- like illness (ILI) programme. However, the seasonal threshold has not been breached.
-The 2020 Influenza season has not started, only one detection of influenza A(H1N1)pdm09 has been made in week 24 (week starting 8 June 2020), since the localised outbreak of influenza A(H1N1)pdm09 and to a lesser extent influenza B(Victoria) in the Western Cape Province, in the first three months of the year.
-The number of laboratory-confirmed cases of COVID-19, continue to decrease. To date 561 have been detected, an additional 10 cases since the last report.
This report summarises data from COVID-19 cases admitted to sentinel hospital surveillance sites in all provinces. The report is based on data collected from 5 March to 5 September 2020 (week 36 of 2020).
-As of 5 September, 64705 COVID-19 admissions were reported in all nine provinces of South Africa, of which 4656 (7%) patients were in hospital at the time of this report, 48747 (75%) patients were discharged alive or transferred out and 11302 (18%) patients had died.
-A total of 438 facilities, 194 from public sector and 244 from private sector, submitted data on hospitalised COVID-19 cases. An additional 106 public-sector and 24 private-sector hospitals began reporting COVID-19 admissions since the National Health Council took a decision on 15 July 2020 to implement DATCOV in every hospital.
-The numbers of reported COVID-19 admissions and deaths peaked around week 27 in Western Cape, week 29 in Gauteng, Eastern Cape and KwaZulu-Natal and week 30-32 in the remaining provinces.
This report summarises national laboratory testing for SARS-CoV-2, the virus causing COVID-19, in South Africa. This report is based on data collected up to 12 September 2020 (week 37 of 2020).
-In the period 1 March 2020 through 12 September 2020, 3,430,265 laboratory tests for SARS-CoV-2 have been conducted nationally.
-As has been observed since week 31, Northern Cape (376 per 100,000 persons) and Free State (287 per 100,000 persons) provinces had the highest testing rates.
-The decreasing trend in percentage testing positive continued, from a peak of 31.4% in week 29 to 11.4% in week 37. Percentages testing positive remained ≥20% in Northern Cape and Free State, were between 10-19% in North West, Mpumalanga and Limpopo, and were <10% in Gauteng, KwaZulu-Natal, Western Cape and Eastern Cape.
