y=Ce^(kt). Using August 1st as y(0)=1,603 cases, using October 1st as y(60)=7.492. K= (ln 7492/1603)/60 = 0.025699315. Setting t=365 (August 1st, 2015) we get 1603e^(k365)=18,998,720 Cases... All data from Wikipedia.
Plague is still spreading, though people in africa are starting to treat it a tiny bit serious and the international response is taking it somewhat serious. The factors have cut the growth rate hard. Despite this, we don't have it anywhere near under control. It's still a major issue, just one you haven't heard about as much due to the fact that some pant sagger got shot for robbing a store and assaulting a cop.
A much more realistic number would be closer to 100k by May, in my opinion, with borderline total negligence. 20k-30k by the end of the year, and then larger projections in a shorter time-frame. An exponential growth, but nothing like the ridiculous claims of 1.4m and similar.
So quoting myself because I was completely correct in my extrapolation. We're at about 18k right now globally at the moment (well, reported, with less than half of that confirmed) so yeah, it is still a terrible plague. Good thing I wasn't using a slide rule, or I might have fallen into Tad's trap!
Still sucks that it took so many retarded incidents in a short time frame to cut down on the threat of importing it here in large numbers.
