I've developed an unbelievably controversial point of view of this mess: the aid agencies acting in Africa are part of the problem. Simplistically, they've enabled the survivability to creep up to a point where the disease can now spread enough to infect a lot more people.

Until there is less squeamishness about quarantining around infected areas this mess will grow and grow. It is deeply disturbing to see just how thin the veneer of disciplined logic that supports civilisation actually is.
