Saint John dropped from national COVID-19 wastewater monitoring site over data accuracy concerns

Saint John has been temporarily removed from the national COVID-19 wastewater surveillance dashboard over concerns about the accuracy of its data. Public Health Agency of Canada officials believe "the sampling point and treatment of the sample prior to testing was the origin of the test variance," said spokesperson Anna Maddison. This suggests "the reported values are not reflective of the community burden," said spokesperson Nicholas Janveau.

Here's how a Calgary lab monitors wastewater for respiratory diseases

Here's how a Calgary lab monitors wastewater for respiratory diseases

Inside the Pine Creek wastewater treatment plant in the south of Calgary, a lab run by the University of Calgary is busy processing wastewater samples from municipalities across the province. This lab, along with one operated by the University of Alberta, started tracing levels of the SARS-CoV-2 virus in wastewater in early 2020 — providing Alberta Health Services with infection trends in different communities. Now the project has expanded to check for influenza A and B, as well as RSV — respiratory viruses that are all currently putting a strain on Alberta's health care system.

Wastewater testing a 'potentially powerful tool' in tracking the flu, epidemiologist says

Researchers at the University of Ottawa are using the wastewater testing strategy that has helped track the ebbs and flows of coronavirus and applying it to influenza. Patrick D'Aoust, a PhD candidate in the faculty of engineering, said the idea came from one his colleagues, Elisabeth Mercier, and the success of the wastewater testing used to track levels of coronavirus in Ottawa. "She said, 'You know we're looking [for] COVID-19. It's an RNA virus. Why don't we just start looking at other RNA viruses?" D'Aoust said.

N.B. wastewater data suggests some COVID-19 cases went undetected in 2021

N.B. wastewater data suggests some COVID-19 cases went undetected in 2021

Public Health officials have raised questions around whether some COVID-19 cases in New Brunswick went undetected in early 2021, after an apparent mismatch between the amount of COVID-19 appearing in wastewater and the province's own COVID-19 testing. The wastewater data shows four apparent spikes of COVID-19 in 2021: on Feb. 8, March 18, April 29 and June 28, all times when there were "minimal cases or positive tests" reported and PCR testing was widely offered. The wastewater testing is conducted by the City of Moncton, which has a partnership with Dalhousie University, and is provided to New Brunswick Public Health. CBC News obtained a copy of the test results, and discussion within the Department of Health about the results, through access to information.
