Researchers at the University of Saskatchewan say COVID-19 levels in Saskatoon have increased again, signalling that the sixth wave is not over yet. On Monday, head researcher and toxicologist John Giesy released this week's COVID numbers, showing a 44 per cent increase from the previous week. "[This confirms] that the viral load is large in Saskatoon, with the second greatest amount ever observed and approximately the same amount as it was a month before," wrote Giesy.
