The most recent study from the Global Institute for Water Security at the University of Saskatchewan shows a growing trend of COVID-19 RNA in its wastewater samples. On Monday, the Institute released its weekly report, showing the city's wastewater saw a 118 per cent increase in viral RNA from July 29 to August 4, compared to a week before. Previously, the wastewater studies were able to predict rising numbers of COVID-19 in the city through traces of the virus found in the city's sewage.
