First, that number is referring to the third-world countries it's currently spreading through (due to their lack of quarantine and terrible hygiene practices).
Second, even in that very article there is a video where they stress that "[even] if you sit next to someone [who's infected] on the bus, you're not exposed [to Ebola]."
unless that person sneezes or coughs and you come in contact with any of the fluids.
and of course, yes that ios in third world countries. however they have had 3300 documened cases, of which at least ONE has made it to the USA, another in france and a few others elsewhere in europe.
now take these percentages, each less then even 1/10 of a percent and figure that figure from 1.4 mil compared to 3.3k.
this is how shit gets our of control. you wishing it away isnt going to make it happen, and with our dipshit president and the other countries for that matter NOT stopping travel, we will have more incidents.
keep in mind its actually easier to keep things isolated in a third world country because people dont actually move around as much. they will stay in their villages, whereas in America or europe, people are traveling much greater distances through transit systems and even just driving to and from work.
I live in one town, i drive an hour to work and infect someone who also lives an hour away in some other direction, and shit gets spread out REAL fast.
