You were using the deaths from the totals column with the cases from confirmed, which is incorrect.

Total death confirmed by bodies. Hard fact.

Lab verified diagnosis of Zaire Ebola Virus count. Hard fact.

Probable and suspect cases unverified. Supposition, not hard fact.

An unknown quantity of probable and suspect cases may have contracted the ZEV and WHO identifies them as such and includes this at the end of their update.

"The total number of cases is subject to change due to ongoing reclassification, retrospective investigation and availability of laboratory results. Data reported in the Disease Outbreak News are based on official information reported by Ministries of Health."

Re-read the page and see if you can find anywhere on the page WHO;s calculation of the mortality rate.

The lower figure can only be found in the mass media who are soft-pedaling all Ebola news.

Have a good day, I'm done with you.

My explanation above walks through step by step, based on the data on WHO's web page. The Center for Infectious Disease Research and Policy (CIDRAP) has published case fatality rate for this outbreak back in June, calculated exactly as I outlined above. For annyone who does data analysis for a living this is common sense; I assumed you don't and was just trying to be helpful and explain.

Total death confirmed by bodies. Hard fact.

Yes, but a stand-alone fact. "All dead bodies" does not equal "Ebola deaths."

We can divide confirmed Ebola deaths by confirmed cases or total deaths by confirmed, probable, and suspect cases but not total deaths by confirmed Ebola cases. Well, we can. But what would be the point?
