Ebola virus disease (EVD) West Africa update for 22-June, WHO-AFRO update...

[CHECK OUT TAB ALONG TOP FOR LATEST EBOLA NUMBERS]

A new Disease Outbreak News has appeared. It shows that cases have risen by ~39 since the last report.

Total suspected/probable/confirmed cases: 567
Total suspected/probable/confirmed deaths: 350 (61.7%)
Total lab confirmations: 385 (67.9% of 567)


The cumulative totals of suspected/probable/ fatal EVD cases, just fatal cases and the numbers confirmed by laboratory analysis. Data are based on WHO DONs. 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.

Reported cases continue to rise most rapidly in in Sierra Leone as we can see from the country-specific chart below..

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.
