Ms Yvonne O'Neill:

With regard to the third question on the lessons learned, the expert panel's report was a major opportunity for reflection on the first wave. The lessons we have learned about asymptomatic presentation have informed a number of the additional interventions. In particular, the serial testing has offered another way of early identification and mitigation of outbreaks. I see Dr. MacLellan has her hand up, so she might wish to say more on that.
