I think this just points to the need to really step up our game if we want to stay ahead of this.
What do you suggest doing to 'step up our game?'
I would initially greatly restrict travel (air, land, and sea) out of Africa and limit it to those involved in aid efforts. Those workers would be carefully observed. If a tight quarantine could be imposed at a level of granularity smaller than the entire continent, then I'd be willing to lift travel bans on the entire continent after they were effective for an incubation period with no sign of spread. However, it is hard to contain a disease area as large as the current outbreak, and the entirety of the continent provides geographic barriers to spread.
If somebody does develop Ebola then anybody they had contact with would be quarantined, with police enforcement (either monitoring devices as are commonly used in house arrest, or guards outside the door). Anybody infected would be isolated in dedicated facilities, with the healthcare workers quarantined. Of course, without an endless stream of flights out of Africa there would be few infections outside of Africa so these measures would be very limited.
First world nations should immediately fund rapid development and testing of promising treatments, offering bounties or fee-for-service models where necessary to get around concerns around marketability of the treatments. Nations really need an Ebola treatment in their bag of tricks even if this outbreak goes away before it is developed. There is no reason there can't be ten thousand greenhouses doing a crash course in wmapp production right now, even if it turns out to be a dud (which seems unlikely). Anybody with a biochem degree could be trained to produce it, and they aren't THAT uncommon. By all means use the drug domestically first, but with the travel ban there won't be much demand for that so you can actually give doctors without borders a good supply of the stuff. The fact is that having a pool of a million people with Ebola anywhere on the planet isn't a good thing for anybody, so even if everybody is completely selfish it is in their interest to fund getting that epidemic under control.
In a nutshell I'd treat this more like a war and less like a recession. The US has an insane 10% unemployment rate or something like that - there are plenty of bodies that could be given the necessary training to get ahead of this if we just got off of our collective rear ends and maybe did something with that nice GDP growth besides build private jets for CEOs. Since this could save the CEOs own hides, they probably won't complain too much about it.
