My understanding is that the Global Fund not only helps to provide medicines to people who have contracted these diseases, but do you also work in the area of trying to prevent the spread, for example, of TB or prevent people contracting malaria? Is there more that could be done about that? Again I go to the issue that, even in our country, they say that one of the main causes of illness is simply poverty. I would like to hear more about that, about the bigger analysis of why it is that we haven't been able to address these problems yet.
