Half a million people die every year in Africa of malaria. No one seems to care about that. However when a couple thousand people die of ebola, suddenly we’re sending troops and other humanitarian aid.
I understand wanting to do something to help. However, charity is the job of Christian missionaries and other private citizens. If the government is going to spend $1 billion it would be arguably better spent on studying ebola and coming up with either a vaccine or cure.
Ebola, on the other hand, is not so constrained.
