Ebola has been largely ignored by the West for the last few decades as its been consigned to poorer African countries. As soon as it starts to risk places to make the oprhan drug principle* obsolete, work to better deal with it will occur before you can say "profit". Hemorrhagic fevers are still quite common - even in the USA, there was fourteen cases of bubonic plague in 2013.   *Namely, the idea of a cure or drug which works in principle, but which, as the condition attacks only poor people or a few rare cases, isn't seen as profitable enough to make the medicine. Several of the WHO's list of medicines they consider a human right for people to get fall under this!   So ebola - scary disease, nasty one, bugger if you get it, but the chances of it widespread taking out the world are rather thin. And if this recent outbreak gets the world more concerned to actually do something about it, it might help us all in the long term!
