Ebola virus disease (EVD) West Africa: 24-June WHO-AFRO update...

Apart from something unexplained going on with the wording &/or numbers in the Sierra Leone portion of the report, the latest Disease Outbreak News (DON) from the World Health Organization (WHO) reports a continuing climb in the case numbers, particularly those from Sierra Leone.

The cumulative totals of suspected/probable/ fatal EVD cases, just fatal cases and the numbers confirmed by laboratory analysis. Latest data are based on WHO DON.[1] Lines use the numbers on the vertical axis on the left, bars use the right hand axis. The percentages are the proportion of fatal cases at the time point indicated.

A reminder:
The chart above, as with all on VDU, is made for general interest only. It is also freely available for anyone's use, just cite the page and me please. It may be that I have misinterpreted the language in the reports (sometimes a little tricky to wade through) or miscalculated some totals based on the way data have been presented. 
There are very country-specific differences in what gets presented to/via the World Health Organization's Disease Outbreak News which make this process less clear than it could be. I recommend you have a read and compare the data from each of the 3 countries for yourself to understand these issues. 
As I've talked about previously,[2] these numbers are all volatile for a variety of reasons, some Ebola-specific, so regard this chart for its trends only.
