“Unfortunately, the hard reality is that we don’t know that much,” said Dionne Aleman, a University of Toronto engineering professor and CHE affiliate who studies health-related systems.

“Without being able to do extensive contact tracing, it’s hard to know what’s exactly happening, and without knowing exactly what’s happening, it becomes virtually impossible to have any success stopping this disease by imposing very minimal, targeted restrictions.”

In Ontario, the Toronto Star reported that hundreds of COVID-19 infections may be going undetected each week because far fewer Ontarians are getting tested on the weekend, leaving possibly infected people more time to expose other people, according to University of Toronto professor Dionne Aleman, an expert in pandemic modelling and a CHE affiliate.

8 p.m. Hundreds of COVID-19 infections may be going undetected each week in Ontario because the province is regularly failing to use its full capacity to test for the disease, experts warn.

The problem is a weekly pattern that’s been clear since the spring: far fewer Ontarians are getting tested on the weekend.

This, in turn, has led to a weekly up-down testing cycle that may be making it harder to control what’s happening in Ontario’s second wave, says Dionne Aleman, a University of Toronto professor and CHE affiliate and an expert in pandemic modelling. If thousands fewer patients’ samples are being collected on the weekend, it suggests possibly infected people may be waiting to get tested, which leaves more time for them to expose other people, she said. “That’s a lot of secondary infections that have happened all because somebody didn’t want to come in on the weekend.”
