Well, I'm genuinely encouraged both by the work we're doing on PrEP, but also in the new pilot that I've announced. The work on PrEP is important, because, if you recall, when I gave a statement to this Chamber previously, we had picked up a number of people in the pre-testing, before providing PrEP—a number of people undiagnosed with HIV—so they were able to actually begin treatment for that at that point, as well as the preventative point about PrEP, and I expect that we will learn much more about how to make sure PrEP is properly available to prevent HIV taking place in the first place. The roll-out that I've announced of the self-testing and sampling at home is important, because other parts of the UK have a variation of that. We've actually got an easier test that we're actually rolling out here in Wales. The initial focus is on chlamydia and gonorrhoea, but that will then roll out into looking at HIV testing as well. We provide nearly 100,000 HIV tests in Wales each year, so there's a significant amount of testing going on. It's not about what we should do; it's how we should do it, and how we should improve what we're doing, and, actually, on this point, we're leading the way across the UK.
