Ebola isn't super contagious. Way, way more people die from the flu every single year than have died from Ebola ever.
EZ spreads by contact, may spread via air (the monkeys in the study cited below apparently inhaled the virus in one form or another), has a long incubation period during which the carrier can pass the virus to others, is mostly fatal, and has no good treatment or cure. Furthermore it has been shown that EZ can be carried by pig populations (it doesn't kill pigs apparently) so now we need to worry about our pigs too:

Combine this with the poor conditions at immigration centers and it looks to me like an oncoming "cluster f*sck" SNAFU for the USA. I fear incoming EV may far outstrip Iraq/Syria in significance but see little activity or awareness at the political level.
