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.
U of S professor believes COVID-19 cases will soon drop in Sask. cities
University of Saskatchewan toxicologist John Giesy says recent wastewater data shows new COVID-19 cases could be dropping sharply in the next few weeks. According to a study released Monday by the Global Institute for Water Security, samples taken from wastewater plants in Saskatoon, North Battleford and Prince Albert showed a decrease in COVID-19 viral load.
