Dr. Cillian De Gascun:

I might let Professor Nolan come in on that point as well but one of the reassuring things we have seen from a testing perspective is that as we have increased the amount of testing we have been doing in the last two to three weeks, the positivity rate has continued to decline.

That would suggest there is not a huge wealth of undiagnosed or undetected infections out in the community but, as I said, Professor Nolan may have something to add to that.
