If you do nothing, if a mother doesn't come for care, if she breastfeeds her baby, the chances of the baby getting HIV are about 40%. So it's about the difference between 40% and zero. This is almost totally preventable. But it requires mothers coming for care and getting the medicines they need, and getting the education and support they need.

I'm not really keen on comebacks. Eurythmics was an incredible thing. When I look back on that work, I feel very satisfied with it.

There's so much stigma around HIV/AIDS. It's a challenging issue, and the people that already have been tested and know their status find it very, very hard to disclose their status, to live with that virus, and to even seek out the kind of information they need. This experience of going to South Africa a decade ago really woke me up to the scale of the HIV/AIDS pandemic in sub-Saharan Africa, how it was affecting women and their children. I haven't been able to walk away from it.
