In reply to Jim C:
I don't know about mandatory quarantine, if it puts many workers off volunteering it could make the problem worse? A rapid and reliable test before travel would seem a good compromise? If such a thing exists...
However... Flying front line staff back on commercial airliners out of countries well away from the infected areas seems like massively tempting fate, and a good way to start shaking public faith in air travel. Having recently been to Morocco and having - very briefly - considered the Ebola situation before travelling, it never occluded to me that I could have been sat next to an infected person for 4 hours, or exchanging fluids with them via toilet taps etc. Pretty dumb of me in retrospect, I had assumed they were getting flown around on military medical transports. Hah, idiot.
A more knowledgable person might correct me, but as I understand it there is no solid consensus on the probabilities/timescales of the virus evolving an aerosol stable form, if that happened and people are regularly flying on jets to/from places well outside the Ebola zones, Very Bad Things could happen. But the aid workers need to travel - who is going to pay for private charters given the massive range of places these people volunteer from?
The only "answer" I've got is that national governments and the WHO should have a better handle on things! The fact they don't suggests a total lack of foresight and planning that doesn't inspire confidence in their ability to handle this or future crises.
