Pursuant to the comment I made during my opening statement, contact tracing is something that falls within the responsibility of the local provincial health authority within the jurisdiction that has the individual they're dealing with.
That said, we've been working very hard with the Province of Ontario to support its efforts in terms of identifying individuals who were on the plane associated with the first index case in Canada.
At this point, it's our understanding that if they haven't contacted 100% of the people who were in the surrounding area of that index case, it's about 99.9%. Unless my colleague the deputy minister from Health Canada has anything to add to that, that's our understanding at this point in time.
