I wish I had more time to talk about results because I would be more than happy to do so. I think we have very impressive results. That's one of the reasons Bill Gates is such a great supporter of the Global Fund as well.
Very briefly in a few seconds, TB mortality has gone down by more than 40% over the last 20 years. That's an impressive result. AIDS mortality over the six years has gone down by 24%. The results are there. We have the models. How can we drive down the diseases? If we diagnose them, if we provide them with effective treatment, we can really control these diseases, but there are a few challenges. The mining industry, for example, particularly provides an environment for these workers where they're very susceptible to these infections. That's why we have to redouble our efforts so indeed we get in before the disease can really get its head up through that kind of multi-drug-resistant tuberculosis.
