The percentage of KP.3 increased from week 17 (11%) to week 20 (38%), with the percentage of JN.1 reducing to 48% by week 20. [...] SARS-CoV-2 RNA not detected (negative result): A negative result can occur because there are no active ‘shedding’ cases in the catchment or because the SARS-CoV-2 RNA concentration is too low to be detected, most likely because there are a very low number of cases in the wastewater catchment. [...] 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.
