A quick chart to highlight the larger and smaller outbreaks and importations of EVD and Ebola viruses, respectively, that have been recorded worldwide since 1976.

I've added in the current tally of 167 suspected/probable/confirmed cases for the 2014 Guinea outbreak but this number is inflated compared to the other entries on the chart because those are reportedly based on confirmed cases; only around a third (59) of Ebola cases in the current outbreak have been confirmed to date.

Thanks to @Pawixx for steering me to the PHE page.

Please note that these numbers differ a little from the World Health Organization's Table [2]. Solving that discrepancy is a problem for another day.
