And the interesting thing about Ebola is that while it's not very contagious it is extremely infectious. Which means that you need contact with just a few virus particles to be infected.
I would bet the deadliness of Ebola has been overstated (at least by a little, probably by a lot). Like any infection, many people who get it are probably asymptomatic, and until recently the vast majority of people tested for it were most definitely symptomatic.
