This donation was made to the CDC Foundation, not the CDC. The CDC Foundation does most of its work outside of the United States. Zuckerberg's donation is meant to help reduce the novel growth rate seen with 2014 West Africa Ebola. We have little experience with Ebola in urban areas. We're currently seeing a doubling of case rates nearly within the the Ebola generation time of 16 or so days. If that reproductive rate is not slowed quickly, in the next few months, then one possible outcome is that Ebola will never go away, and will exist as yet another terrible disease afflicting the poor. Moreover, imagine if we could eliminate a disease like malaria for a few billion dollars. The cost-benefit of that would be astounding. It makes sense to try and eliminate Ebola now, not just prevent it from reaching the US.
