Viral COVID levels in wastewater increased in Saskatoon and North Battleford last week—but fell in Prince Albert.

The University of Saskatchewan research team notes all three cities still have relatively low totals compared to earlier in the year.

Saskatoon was up 53 percent last week, but still had the fifth smallest viral load in the past five months.

North Battleford was 38 percent higher while Prince Albert was 51 percent lower. The Prince Albert total is the second smallest in the past 18 weeks.
