Courtesy of Reddit and user c0mputar, here are the 4-day daily case totals of reported Ebola cases going back to late August:
With all the caveats regarding "official" reported numbers vs. actual cases, and noting that this includes periods where nations added - and subtracted - thousand-plus numbers into short periods, what's notable is that since late August, this outbreak hasn't been below 100/new cases day. It's also never gotten as high as 200 cases/day.
IMHO, that points to this range being the maximum number of tests that can be run in one day, and/or the maximum number of people who come forward for testing, versus any approximation of the actual number of people infected in any place or period.
Which explains everything else about supposed flattening of the growth curve.
The fact that it isn't going anywhere, up or down, is proof that there are always (for the last nearly 4 months) at least 100 people so sick with Ebola that they'll finally drag themselves to an ETU - or collapse in the street - for isolation and testing. (It's more than that, but a notable number of them die before testing, which opts them out of the process with some finality, while simultaneously letting those nations elect to not count them in the death stats, since the cause of death is thus "unknown". How convenient. Shovel, shut up, and keep the news cheerful. QED)
So what this tells us is more like a tachometer than a speedometer of the infection: it tells us how fast the labs are cycling tests.
It doesn't tell us what gear the infection is in, if you will.
It might be fair to think things were winding down, except for recent note that burials are humming along everywhere, while stacks of unburied bodies are being discovered all over Sierra Leone, while in Guinea, the spread of the disease simply refuses to taper off. Liberia seems mainly to have mastered the use of pencil erasers to solve their statistical problems.
