Cabinet Secretary, you recently highlighted the importance of understanding the real levels of HIV in Wales, and I think, as you added, the number of people living with HIV here is probably underestimated. The Terrence Higgins Trust have produced statistics that relate to the UK as a whole, with a breakdown, but there's very little data in their statistics relating to Wales specifically. Aside from looking at providing testing in communities and self-testing kits, will you be carrying out further Wales-focused research to understand how many people in Wales are HIV positive and, importantly, if there any parts of Wales with a higher number of people suffering than elsewhere?
