Readers Ask: Should we have more testing?

·1 min read

Brandon Sun readers request specific questions be asked about COVID-19.

Question: It seems that positivity numbers are falling, though they still remain two-to-three times the three per cent rate that Dr. Roussin described previously as “concerning.” But, the number of tests being done has also fallen. If more tests were being done, would we be finding more cases, and thus be getting ahead of the curve instead of just trailing after it?

Dr. Brent Roussin: It depends. Asymptomatic testing, we’ve shown time and time again, has limited benefits on the grand scale. There’s certain times where it can be very targeted and (a) benefit. But, we see the asymptomatic testing is less likely to find positive cases.

We see our test positivity rates here in the second wave remain fairly high, although dropping. It’s dropping with their stable number of tests. So, it is telling us what the trajectory is.

What we see in the in the second wave … we’re just not seeing many other respiratory viruses. This time of year, we see RSV (respiratory syncytial virus), we see influenza, and we’re just not seeing any viruses circulate. So, right now, if somebody’s going to have respiratory symptoms, it’s very likely to be COVID.

That’s why our test positivity rate remains high because there’s just not many other things out there making people ill. So, we are going to follow that over time. There are times for asymptomatic testing. But, we do have to ensure we’re using our resources effectively.
