COVID-19

What do B.C.’s COVID-19 numbers actually reflect?

Mar 27, 2020 | 2:19 PM

KAMLOOPS — Earlier today (March 27), provincial health officer Dr. Bonnie Henry and B.C. Health Minister Adrian Dix made a presentation on COVID-19 projections in the province.

Officials from the B.C. Centre for Disease Control have done modelling work to anticipate the number of cases in the province, and prepare hospitals to care for critical and acute patients.

The province says the rate of growth of COVID-19 cases is being impacted by stringent measures introduced over the past few weeks.

Many CFJC Today readers, viewers and listeners have been asking questions about the true number of cases in the province and testing measures. Today, we asked Dr. Henry about those concerns.

CFJC Today: What’s the estimate for the actual number of COVID-19 cases in B.C., and how accurate can today’s projections and models be if the demographic of people being tested is relatively exclusive?

Dr. Henry: I’ll address the second question — the demographic is not exclusive, that’s not the right way to characterize it. The focus is on people at highest risk of having this and the highest risk of creating issues with our healthcare system. We want to be able to absolutely detect outbreaks in hospitals, we know that our long term cares have been affected, particularly in the Lower Mainland, so focussing on those people who are in that milieu is important to help us understand risk and to be able to determine the people at highest risk in those settings. So we’re not excluding people; what we’re doing is focussing the testing on where we don’t know the source.

And again going back to estimations of numbers, there’s models that help us do that and I presented our expected — the numbers that we’re seeing right now is about 130 cases per million that would give us in the range of 2,000 to 3,000 people probably in the province that were infected at that point in time. But again, these are just models. So our testing strategy has been to test widely and we know that there’s transmission happening in communities that we don’t recognize and that’s where we have to focus our testing and our public health response on those as they pop up.
