Ottawa covid-19 wastewater surveillance

The National Capital Region is one of the first communities in Canada to conduct daily wastewater readings to help inform its community response in the fight against covid-19, thanks to innovative research from the CHEO Research Institute (CHEO RI) and the University of Ottawa (uOttawa).

The figures below were created by researchers at CHEO RI and uOttawa. Learn more about wastewater epidemiology and its role in covid-19 surveillance on Ottawa Public Health’s website.

The science supporting wastewater surveillance is rapidly evolving. The plots are currently for research only and presented to the public for discussion only. Wastewater and public health scientists have noted the early wastewater covid-19 signal increase in mid-July that preceded Ottawa summer and fall case resurgence.

* Viral copies data is normalized using a seasonally stable fecal biomarker; pepper mild mottle virus (PMMoV). See methods for more details.
