All it takes is one person on a flight out of Angola to anywhere in Europe and then another on a transatlanic flight.
This article should help the sheeple (who don't even know this is happening) feel better. </s>
I'm sure there are others here who know more than I do about it, but it's my understanding an Italian died after returning to Italy from Africa and nine people or so were quarantined - this would have been last week when there were millions of people in Italy for the Pope's viewing/funeral. That's the thing that, if correct, bears the most potential for creating a serious global problem (IMO).
Avoid elaborate burial rituals involving handling the body repeatedly of someone that died of Marburg and you'll be OK.
That may be whoever I believe that an outbreak of this kind would be dealt with much faster and more effectively than it is currently in Africa. For example most American's understand how disease is spread and would be more willing to listen to the CDC or state health authorities. I doubt there would be the mass hysteria there is currently in Angola over health care workers in decontamination suits We also do not wash our own dead which is where a lot of the infection is being spread in Africa. Overall we have a higher level of sanitation. It could spread over here however I do not think it will take the toll it is currently especially since it is not airborne.
