Mr. Paul Reid:

I will comment briefly and I will then ask Ms O'Beirne to comment further, as we have some facts and figures to hand. What I was referring to then, and which is still a factor that we strongly encourage and it has got better, was where we make contacts of positive cases. We now organise a test for them on what is called "day 0", their first test, and then another test on day 7. What we saw originally was some people not coming forward for their tests. We obviously try relentlessly to make contact with them and set up appointments for them. Equally, we do that on day 7. We have seen an improvement and also regarding those coming forward for the day 7 tests, but it is part of our contact tracing resources.
