Thank you so much.
The invitation to bear witness here this afternoon is very much appreciated. Thank you to the committee for inviting me.
I'm an infectious disease physician and clinician, scientist and researcher at Dalhousie University, and I speak from that perspective today. Although I work with and collaboratively around both the Nova Scotia Health Authority and the public health department at the government of Nova Scotia, I speak as an individual here today.
I want to provide a bit of context perhaps of somewhat of a microcosm of the pandemic response from Atlantic Canada, specifically in terms of Nova Scotia and our response. As an infectious disease person, I think the things that have made our response arguably very successful.... We have, even with our current wave, 346 per 100,000 people who have had COVID-19 infections. To put that into context, other provinces include Ontario at 3,200 per 100,000 and Saskatchewan at 3,800 per 100,000. Again, as I said, there were 346 per 100,000 here in Nova Scotia.
We have arguably had a successful response and, as an infectious disease person, I would say there are several components to the response that are rather important.
Number one, we understood speed of response fairly quickly, as in infectious disease, speed is always important. Number two, that speed has added distance between human beings which, with a respiratory infection, is an incredibly important thing to do. Number three, in addition, there has been awareness of the infection and where it is through the use, primarily, of an exceptional amount of testing, both in people who are symptomatic and those who are asymptomatic, throughout the pandemic. The fourth, less quantitative and I think exceptionably important thing that we have managed to do as part of our pandemic response is to engage the community, not just as passive members of the pandemic response but as active members in being tested, getting tested, being the testers and being actively engaged throughout. I'll speak briefly to each of those components.
On the first part, speed, I'll use our most recent wave as an example. We went from zero to six cases per day from about last June until November, when we had a small number of increased cases up into the low double digits. Until then, we had gone back down to zero to six cases, again per day, with almost zero unlinked epidemiologic cases. For those who don't spend their lives looking at microbes and infectious diseases, that would imply that community spread was limited, which is very important. We knew where the cases were coming from and how. That changed in April. Between April 15 and April 21, we started to go into double digits of new cases per day, and there was the beginning of a signal by April 27 that we had community spread when we hit 97 cases per day. At that point, our restrictions went from being fairly open to being very closed.
In the intercurrent period between our waves, the Atlantic bubble still existed, and I'll speak to that in the distance part of things, when people coming into the region were required to quarantine. Anyone coming in from outside the Atlantic bubble.... In fact, our bubble burst a couple of months ago when our cases started to go up a little, and even people coming from within the Atlantic provinces were required to quarantine for 14 days.
The reason that's important is that we were able to keep track of where the cases were and how they were. At 97 cases, our government closed down public places where you would be unmasked and indoors, both retail and restaurants, etc., which had been open in between waves. Gyms were closed down very quickly, and people were asked to be at home. Then the cases went up even higher, into the hundred range, and the whole province was shut down. That's the speed part of things.
Seeing cases go up and community spread go up met the criteria that we have in place here that are quantitative: high numbers of unlinked cases, high reproductive numbers of the virus and case numbers going up in the community per hundred thousand. That was done very quickly, and distance was added. Inside, and in places where people can't mask, they were asked to do so quite a bit.
Then there was awareness. We always maintained asymptomatic testing between waves, so we knew when there was asymptomatic virus in the community. We also ramped that testing up to between 1.5% of the population per day when we went into this wave of the last week and a half ago and 5% of the population per day in our hot spots. In addition to that, awareness through our symptomatic testing was maintained.
On the engagement part, which I will be happy to give testimony on later, is the fact that we ran much of this testing outside our labs. Community-based volunteers were doing this work. There were taught to test, swab and provide an exceptional resource to people at the time, so we had a warning detection system for virus in the community.
I think, together, this has been an example of how we may be able to do things better in Canada and in different parts of the world as we go forward in this pandemic. The effects of speed of response, distance of people, awareness through diagnosis, and engagement of the community cannot be underestimated. I'd love to take questions on that afterwards.
Thank you for allowing me to speak.
