March 2024 (Weeks ending 10 March to 31 March) 6 Monthly Wastewater Surveillance Report COVID-19 Trends in Ministry of Health Regions Regional analysis of the wastewater data is shown in Figure 7. [...] SARS-CoV-2 RNA detected (positive result): A positive detection in the wastewater indicates that at least one person has been shedding SARS-CoV-2 into the wastewater at some point during the period that the sample was being collected. [...] This conversion considers the flow rate of wastewater entering the treatment plant (the influent) and the population in the catchment. [...] The flow rate is the total volume (m3 per day) recorded at the inlet of the wastewater treatment plant over the 24 hours during which the sample was collected. [...] Limit of quantification: The lowest concentration of the target that can be reliably quantified is referred to as the limit of quantification.
