Dr. Ronan Glynn:

I thank the Deputy. I might ask Professor Nolan to answer in relation to the proportions but I would argue that on balance, the return of children to school over the past month has been very successful. That is not to say it has been without challenge or significantly increased activity for public health teams around the country. There are 23 schools or childcare facilities where more than one student or staff member has been identified as having Covid-19. That is not to say that there are 23 schools or facilities in which more than one case has been linked to another case as a result of some interaction within those facilities. We were clear, in the weeks leading up to the reopening of schools, that a proportion of cases occur in children. To my mind, those proportions have not changed.

The absolute number of cases has gone up week on week but in proportion to the increases in cases we have seen across the entirety of the population. Professor Nolan may want to come in on the detail.
