How the Speed of Response Defined the #Ebola Crisis

These charts are based on an epidemiological model created by the Centers for Disease Control and Prevention, using figures from Liberia and Sierra Leone, two of the countries hit hardest by the epidemic. In the third, Guinea, case counts have been unreliable.
Large-scale intervention did not begin until late August and early September, and the C.D.C. model suggests that was too late to stop the epidemic from killing tens of thousands of people — and perhaps many more — by the end of the year. Had successful interventions been started much earlier, the total number of cases would have remained below 5,000.
