You know, it's crucial to get local communities involved.
I don't know if you want to add something to this as well, Doug, but just taking the zinc example, just like here, when children present with diarrheal disease, one of the things is that moms don't always bring them to the hospital or to the clinic or the health post. Of course in Africa many health infrastructures are broken, so what we're trying to do is rebuild.
The way we work is to work through national governments to help them, but also to layer on our value-add to local INGOs that are working in that last mile. I keep calling it the last mile, because 80% of really poor people live very far away from urban centres in Africa. You have to really extend health close to home. That's the reality. We do it through a variety of ways.
Getting back to the zinc and ORS, about diarrheal disease, if you don't get the communities involved, through education and then social mobilization, using all sorts of methods, in terms of recognizing that zinc and ORS is a solution and will help their children be less sick.... I was just in Senegal, in a rural health post. They introduced us to all the grandmothers who had come in as part of the community involvement in this program. The grandmas--everywhere in the world, one would like to say, but in Africa particularly--have a very strong voice. Grandmas are being educated on the nutritional elements of helping to add micronutrients, plus making the local diet more nutritious, and then they're imparting that wisdom to their daughters and their children. That's an example of getting communities engaged and involved in using educational techniques and others to communicate a message so that you're getting closer to home.
