Estimating the Future Number of Cases in the Ebola Epidemic: Liberia and Sierra Leone

 26 September 2014: 

"The first cases of the current West African epidemic of Ebola virus disease were reported on March 22, 2014, with a report of 49 cases in Guinea. By August 31, 2014, a total of 3,685 probable, confirmed, and suspected cases in West Africa had been reported. 

To aid in planning for additional disease-control efforts, CDC constructed a modeling tool called EbolaResponse to provide estimates of the potential number of future cases. If trends continue without scale-up of effective interventions, by September 30, 2014, Sierra Leone and Liberia will have a total of approximately 8,000 Ebola cases. 

(...) The EbolaResponse modeling tool also was used to estimate how control and prevention interventions can slow and eventually stop the epidemic. "
