I have heard EI is considering infecting some members and going to the States and Europe to contaminate people, this is chilly

*EI=ISIS
I don't think this is very plausible. It would take very specific timing which is somewhat random for this to work also as soon as it becomes apparent that this is happening travel could simply be restricted to/from west Africa to prevent this from working.
Well, how long does ebola stay on a corpse? ISIL has organized branches well west of Sinai, so I'd guess you'd just need an infected corpse for non-Arab ISIL members to use in a suicide mission. They'd just rub it all over themselves or cannibalize the corpse like they're on Walking Dead. Idunno how many virgins their anti-caliph prescribes for that kind of hardcore martyrdom, though... at least 100, hopefully.
(I'm guessing "anti-caliph" is appropriate since it's basically a Sunni version of the HRE's anti-pope ... ETA: On second thought, I don't recall the HRE's anti-pope telling people to eat human corpses infected with ebola so they could infect as many foreigners as possible before they bleed to death from every orifice. -But history's written by the victors, so who knows?)
