Waste water in London, Ont. is showing high COVID positivity

Waste water data has become a valuable asset in determining the level of COVID-19 within a community and in London, it shows an increase. The January surge of Omicron quickly dissipated in February, but COVID cases have seen an increase in the last few weeks based on data from waste water testing data. “You don't want to look at one sample in isolation, you want to look at sort of the trend. And what I've noticed is if I look at the month of February versus the month of March, we're around three times higher,” said Chris DeGroot, an assistant professor at Western University.
