We expect to learn an awful lot from the PrEP study we're engaged in—not just people presenting themselves, because it is a genuinely nationwide point, but the broader engagement with sexual health services. So, the point about making testing easier—it's all part of trying to reduce stigma as well. There's a challenge about people coming forward to take advantage of the testing that is already available, so the easier we make that, the more we talk about it, frankly, the more likely we are to have people come forward. And we can of course be confident that there are people living in Wales undiagnosed with HIV, because we discovered some of them by accident in the PrEP testing. We thought we would discover some, because we're actually getting to people who have riskier sexual health behaviours than others. That's why, even the people who have undertaken PrEP, we know that nearly a fifth of those people have actually got other sexually transmitted infections. So, we're actually dealing with the right population of people, and I look forward to addressing the Terrence Higgins World AIDS Day event here in the Senedd at the end of this month, while speaking about this Government's commitment to eliminating HIV here in Wales.
