Mask as needed: wastewater data shows COVID levels still higher than last June

Go into any store these days and there's a mixture of people wearing masks to prevent the spread of COVID-19 and those who are opting not to wear one. It may have people feeling like they're in COVID-19 limbo. Dr. Hsiu-Li Wang, the Region of Waterloo's medical officer of health, says currently there's "no cut and dry threshold" when it comes to mask wearing and "it will vary according to individual comfort levels."

Wastewater testing shows Omicron subvariant circulating in Waterloo region

The University of Waterloo's wastewater monitoring shows an Omicron subvariant has been detected in Waterloo region. The BA.2 subvariant appears to be even more transmissible than the original Omicron mutation of COVID-19, says Dr. Hsiu-Li Wang, medical officer of health for the Region of Waterloo, but there's no evidence that it is a more severe mutation. The samples came from the water treatment plant in the City of Waterloo on Jan. 4 and 9 and from the University of Waterloo water treatment plant on Jan. 18, researcher Meghan Fuzzen told CBC Kitchener-Waterloo. They were independently confirmed by two different out-of-province labs.
