Extremely unlikely, that it's not even an edge-case. I dare say that anybody who has seen directly or indirectly the effects of Ebola, would be more than aware of the risks and if anything, be more inclined to over-react (look at how leprosy was treated socially historically or even AIDS).
that's gotta be one the most presumptuous questions on hn I've ever seen. DRC has been dealing with Ebola outbreaks since the 60s. How do you imagine that they would be unable to comprehend? the clear implication is that they're too dumb.
