Canadian Wastewater Survey (CWS): Modelling Report

Publication Summary

This document shows the current level of SARS-CoV-2 in the wastewater in cities across the country. In the plots below, the horizontal axis displays the month, and the vertical displays the wastewater signal as SARSCoV-2 genome copies per ml (gcp/ml). The green and orange threshold lines display the historical 25th and 75th percentile, respectively.

Information on how these values are calculated can be seen in Appendix 2: Technical Documentation. The current level compared to historical data and trends for each city are shown in the top left corner of each plot, and the key messages highlight recent important changes in the data.
