Some Saskatchewan COVID-19 wastewater numbers hold steady but show jump in BA.2
COVID-19 wastewater numbers show the amount of virus in two cities remain relatively unchanged and decreased in a third.But they also show the more transmissible BA.2 strain of the Omicron variant is spreading.The new strain now accounts for 70 per cent of all detected COVID-19 RNA in North Battleford wastewater, up from just below 50 per cent the week prior. China battles multiple COVID-19 outbreaks, driven by ‘stealth omicron’ variant In Saskatoon, BA.2 accounts for 42.5 per cent, up from 19 per cent.And in Prince Albert BA.2 now makes up 13.6 per cent of detected COVID samples, which increased from around five per cent.Almost all of the remaining detected virus in Prince Albert and North Battleford is BA.1, the original Omicron strain.A little more than 15 per cent of the virus RNA in Saskatoon’s wastewater is neither BA.2 or BA.1.Toxicologist John Giesy, who runs the University of Saskatchewan Global Institute for Water Security, which measures the amounts in the three cities, said it’s likely Alpha or Delta, though he couldn’t be sure.He also couldn’t say how the strain may affect Saskatchewan residents and hospitals, because the lack of timely government data and public health orders, combined with a largely vaccinated population, makes it harder to determine patterns.
