Ok, I think anyone here generally understands how dangerous Ebola is and could become if it continues to spread.
That being said, already this century:
Smoking has killed roughly 60 million people
HIV / AIDS has killed 20 to 25 million
Malaria has killed eight million
Diarrhoea has killed perhaps 15 million
We're a long ways yet from Ebola competing as a worst human disaster candidate. To put it in stark perspective, it could kill a million people before it's contained (100+ fold more than it likely currently has), and it still wouldn't get near the health disasters I listed. I don't really understand why people persist with inflating Ebola's stature (or downplaying the other health disasters, however you want to look at it). The only conclusions I've come to, are that Ebola has been sensationalized for years by Hollywood and the media (on-going), and its mortality rate and rapid nature are obvious fear points. I still don't see how the fear adds up when compared to millions of children dying from diarrhoea, except that these are things most people think they can't get / won't die from.
