Nova Scotia Health researching cancer risks in hundreds of communities

For example, some people may not be able to afford tests needed to identify cancer-causing factors like radon exposure or arsenic in well water. Others may not be able to pay for measures needed to reduce or eliminate those risks after they've been identified, Rigby said.

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

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.
