Mr. Philip Carroll:

It is difficult to assess this. I mentioned in my statement that we have seen active outbreaks and clusters in plants in other jurisdictions. It is difficult to pinpoint a single reason we have managed to reduce the number of cases. As I said earlier, when the spike hit there was a connection with what was happening more widely in the community. That said, the measures have proven, over a period of time, to be pretty robust. One point I would make is that when there was some disagreement or uncertainty about the relevance of asymptomatic cases, we found that, having had a spike of cases as a result of mass testing at particular sites, a substantial number of those positive cases came from people who were completely asymptomatic.
