Other Talks in the Series: Neglected Tropical Diseases

This is Adrian Hopkins. We are going to go into the second talk around onchocerciasis or river blindness. The first part we talked about the actual disease, the vector, the parasites, and how we could treat it on an individual basis, by looking a little bit forward to that we could actually do the much treatment. Now, we are going to move much more into the various ways of controlling the disease in the community with the possibility of eventual elimination of the disease. Certainly in some foci, it's very close to that in America, and there are some areas in Africa already where we've had some good success.
The way I thought we would do this would be looking at it from a program point of view, and asking really three main questions. Where are we now with our programs? Because some of these programs have been going for years. Where do we want to be? We had hoped that we would be stopping treatment everywhere by 2025. That may happen, but it possibly or probably won't happen in the Democratic Republic of Congo, in South Sudan, probably in Angola, not because Angola's difficult, but because Angola hasn't got its act together with its treatment strategies yet. Possibly, in the Central African Republic where we had a good program, but with constant conflict, that's been a problem, and also, in Yemen, the situation is the same; we've had some good planning, but then, with the civil war, we've had major problems. But, we do hope that we will eliminate the transmission of the disease in most areas, and we're already celebrating some success in the Americas- four countries have been declared free of the disease. We want to start doing that in Africa, where we should have started in Africa in 2018. Now, that it's already 2018, actually, nothing has got done, so we hopefully will celebrate in 2019. So, that's where we want to be, and then we have to look up just a few principles as we look at what we need to do together. How do we actually reach the end game as it were? What do we need to do? We'll look at those under some of those headings that you see on this slide. The next slide is just where are we now?
