Summary of RNA detection from SARS-CoV-2 in wastewater from four schools. Quantification of N1 and N2 genes plotted together with clinically confirmed cases (CCC) reported to school administrators during the same timeframe. Arrows in the CCC columns refer to clinically identified cases on dates that were different from wastewater sample collection, with the number of arrows indicating days before (upward) or after (downward) the date indicated (e.g., 2 downward arrows on January 13th indicate a clinical case on January 15th).
