Well the data source is the current WHO-Africa Ebola update page which makes the distinction between suspected, reported and lab verified cases.

I’m just guessing here, but probably the tallied deaths under the heading of Ebola updates are all Zaire Ebola Virus deaths. Haven’t yet come across any mention at all of Lassa or other hemmoragic disease.

I found the data set limited to confirmed lab cases and deaths specific to those cases, from WHO. 574 deaths in 1009 confirmed cases as of 1 August, or 56.8%, so very similar to my estimate. See: http://www.who.int/csr/don/2014_08_04_ebola/en/

Your data source is also correct, you have to use the deaths and cases from the same column, e.g. confirmed cases. You were using the deaths from the totals column with the cases from confirmed, which is incorrect.

WHO fact sheets for the others are on the right-hand side.
