An interesting difference between the current strain and the one talked about in that book, less than 50% of victims with the current strain "crash and bleed out". In previous outbreaks, the number was as high as 75%.
As I become more informed about ebola, I am starting to seriously doubt historic statistics on this. Setting aside the mutation issue, it seems like actual reporting of entire cases ranged from very poor to marginally bad. It seems like statistics like that should always have an added parenthetical "that we know about."
Not judging - the data defines the statistics. Poorly refined data means poorly refined statistics. Just saying that I'm not sure the historical numbers are very helpful.
