I’m not doing this professionally, just out of curiousity. Yes, I was using the suspected cases rather than lab confirmed, since earlier in the outbreak it was necessary due to small sample size. Of course there is the error that you are getting some cases of lassa (and others) thrown in the mix, but from what I recall from WHO’s methodology, suspected means Ebola as the primary diagnosis so it seems reasonable. I haven’t run the numbers for confirmed cases, but if it is that much difference then the cause for the disparity would need to be nailed down.
That’s ok, I’ve done the ‘rithmatic for you.
Using the laboratory confirmed ebola cases and deaths by my calculations the mortality rate is:
Aug 01 887/1009=87.90%
July 30 826/953 = 86.67%
July 27 729/909 = 80.19%
