Nothing really works well when a life threatening disease is on the loose, but it is pretty clear that the virus has no room for human sensitivities and an approach to stopping it should not either.
The most pragmatic thing to do (if stopping the disease is the dominant priority) is to immediately impose draconian quarantines:
1. Have you been anywhere outside of the country? Then you get a 21-day quarantine.
2. Have you potentially been in contact with someone who might have ebola? Then you get a 21-day quarantine.
Would this this hurt the global the economy were all countries to enact it? Probably.
Will it stop the Ebola outbreak? Probably.
Right now, the politicians are trying to keep people calm while they cross their fingers and weigh their options. However, don't think that full, national-guard-imposed, shoot-on-sight quarantines are coming world wide if the virus keeps spreading outside of Africa.
You can sense the BS with all the public service announcements that Ebola is hard to catch because you have to come in contact with the bodily fluids of an infected symptomatic person and then touch a mucus membrane. (Under their breath, the doctors note that you should also stay three feet away from an infected person sneezing.) So now you have the potential for doorknobs, handles, etc. to be coated with Ebola-infected saliva that is viable for days, and you expect people to not every touch a mucus membrane (during allergy season) unless they have just washed their hands.
In short, you are naive or brainwashed if you are not worried right now. I am not saying panicked, but you should be worried.
