Yes.
Very quickly, with HIV the challenge is mostly on the prevention side. We've made a lot of progress on the treatment side. We are able to save people's lives and allow them to lead healthy lives with antiretroviral treatment. On prevention we need to scale up our efforts, mostly in two areas, one being adolescent girls and young women. This is where most new infections take place in Africa, at an additional almost 900 a week. It's massive. Then there are the key populations of people who are most particularly vulnerable to HIV, such as sex workers, men who have sex with men, and drug users in particular. This is where we absolutely need to focus our efforts.
Thank you.
