There's no serious objection to either end of the giving chain--donations are good, and education and mosquito nets are good. But donations can slow or cease based on a variety of factors, and then problems that seemed solved won't be solved anymore. An enduring solution really has to be internally self-sustaining. (Nations with good sewer systems pay for the maintenance themselves.) It's not clear how to structure voluntary donations so they lead to a sustainable solution. Good public health is necessary for developing a sustainable solution, but by itself it is not sufficient.
