New data from researchers at Dalhousie University show that Omicron was in Nova Scotia wastewater weeks before it was identified by the province — and even before the new COVID-19 variant was reported by South Africa. Graham Gagnon, professor, and director of the Centre for Water Resource Studies confirmed in an email that: “Our team detected Omicron , retrospectively, in Nova Scotia wastewater in mid-November and will be able to provide further information in the future.”
Saskatoon sewer samples show highest ever amount of COVID-19
Researchers at Saskatoon's Global Institute for Water Security say they've found the highest amount of COVID-19 since the study began. In a report released on Monday, the institute said samples taken on Aug. 15 and 17 showed the highest amount of COVID-19 RNA in its wastewater samples. It showed a 348 per cent increase in viral RNA in samples taken from Aug. 12-17, compared to a week before.
