COVID-19 could be making a comeback in parts of Saskatchewan.
The University of Saskatchewan on Monday released its weekly wastewater report, which showed the viral load in the city had increased by 742 per cent compared to last week. The levels had decreased in each of the previous two weeks.
The dominant strain at 89 per cent is Omicron BA.2, while Omicron BA.1 makes up 11 per cent of the viral load.
Prince Albert (56 per cent increase) and North Battleford (up 250 per cent) also saw the viral load rise in their wastewater systems. However, the university warned the results in Prince Albert may be skewed due to high runoff.
“We were informed by the treatment plant operators that average daily flows in the past weeks were approximately 15 per cent greater compared to the previous week due to the impacts of meltwater,” the report stated.
“Therefore, the per cent changes need to be interpreted with caution.”
The University of Regina also released its wastewater study Monday and it said viral levels had decreased but “are plateauing at a high level.”
The U of R’s study said BA.2 remains the dominant strain in Regina, Moose Jaw and Swift Current.
The data is considered an early detection for future outbreaks.
