First, it's important to clarify that we're not talking about a goal of eradicating these diseases. That's completely impossible with the tools we have. We would need completely different tools, like very effective vaccines that we currently don't have for these three diseases.
What the SDGs say is to end AIDS, tuberculosis, and malaria as epidemics. This is basically defined as the reduction by another 90% to a low-level endemic so that they can't reappear as epidemics. That's the goal. That's more realistic than what some people might associate with ending them. It's not the eradication. It will be difficult enough. My prediction would be, I think, in many countries we can achieve that.
Then there are countries where the political situation is so difficult, so bad, that whatever we do and whatever money we might have.... We will not achieve ending these epidemics in Yemen right now, or in South Sudan. It will be challenging from a technical but also from a political point of view.
I do expect by the year 2030 that the number of countries that require this kind of international support will have decreased. I think many countries by then will be in a position to take over those costs, and there will be a concentration on fewer countries. We will need to concentrate our efforts on the poorest, the most fragile countries.
By then it might be that the international community will say, look, with that freed-up capacity, please address other health issues. There is more attention now to non-communicable diseases and other diseases. That's a decision that our respective boards will make when the time comes. At the moment we are still very busy driving down the diseases that we have a mandate to address.
