Regardless of sourcing the information, the information is incorrect. According to this graph, Ebola is doubling every 60 days now -- so there has been some improvement.
Best way to keep up on this, that I can tell, is to google "ebola africa timeline wiki", and pan down to the timeline, near the bottom of the article. You'll see the graphs.
My favorite graph for keeping track is the logarithmic scale based on population , because it's easy to see where infection totality is: it used to be at 1 1/2 years, and now is about 5 years out.
Another thing of interest that I noted, though: The infection rates before a country mounts a serious response, can be as fast as doubling every 3 or 5 days. For that reason, I think our CDC's active attempts to STOP a proper response, was the worst thing they could do.
Just something to think about.
