I think most people don't see this outbreak as an emergency. Four thousand deaths means nothing these days. In the days of Biafra, about 1 1/2 million people in the Ibo breakaway state starved to death (1967-9). What is a few thousand people compared to that or many other starvations? I don't mean to sound cold about it, but it's the only reason I can think of. We just don't care.
