Ebola Zaire + USA Immigration Centers = Utter Disaster?

Is anyone else concerned that at the same time we have set up large immigration centers with poor sanitation conditions, we also may soon see the Ebola Zaire (EZ) virus enter the USA? If that occurs and EZ gets to one of the immigration centers, then the immigrants will undoubtedly flee, scattering throughout the population. The result would be a disaster of almost unbelievable proportions (of course it might be a disaster even w/o the immigration centers, just not as rapidly spread).

The incubation period for Ebola Zaire is 2-20 days and the fatality rate is 80-90%. There is no vaccine; there is no cure.
