COVID-19 wastewater data has offered clarity throughout the pandemic, providing glimpses into what cities and hospitals could be facing in the coming weeks.
And it remains one of the only sources of timely information regarding the spread of the coronavirus in the province.But the lead scientist at the University of Saskatchewan’s Global Institute for Water Security, which monitors the levels of virus RNA in the wastewater of three cities in the province, told Global News the information is not as helpful as it once was.“What I used to be able to do was get on the (COVID-19) dashboard for the province and take those numbers off of there and put them into my calculations,” toxicologist John Giesy said.“Well, I can’t do that anymore.” Saskatchewan students and teachers react to COVID-19 restrictions lifting Giesy said the numbers can still show trends and overall increases or decreases in the amount of COVID in cities.
But without other figures to compare the wastewater data to, Giesy said it’s much tougher to predict things like hospitalizations and the amount of new cases.Giesy used to use the provincial government’s daily COVID-19 statistics to gain a better idea of the relationship between different variables.
A large surge during the fourth wave would likely mean more patients receiving intensive who would stay in hospital for longer, for example.
