This document consists of public data published by the World Health Organization (WHO) visualized in a variety of charts. It is hoped that this alternate way of looking at the data may prove useful. The current intent is to update this site on a weekly basis. Typically, each Wednesday data is formally released for the prior epidemiological week. The WHO considers the epidemiological week to run from Monday through Sunday.
We intend to maintain this document until the ongoing west African epidemic of Ebola virus disease (EVD) is brought under control.
The tables found in this section contain the data from which the subsequent charts are generated. Table contents are organized according to the current WHO protocol which segregates statistics of countries with widespread transmission of Ebola (Table 1) from statistics of countries with more localized transmission of the disease (Table 2 and Table 3). Each table’s totals only reflect the countries residing in the table.

1 As of 11-Jan-15, there have been 26 cases of EVD in the four countries with inactive localized transmission of Ebola. Nine deaths have resulted.
As of 11-Jan–15, 21,296 cases of EVD and 8,429 deaths are associated with the outbreak.
The primary data are published by the World Health Organization under the nomenclature disease outbreak news, situation reports, and situation summaries. Operationally, early data are contained in the publications labeled “disease outbreak news” and more recent data are contained in publications labeled “situation reports” and “situation summaries”. The disease outbreak news reports appear to be topical and intermittent. Early data concerning the outbreak were of this nature. The first situation report was published 29-Aug–14. The situation reports are more systematic and document the status of the global outbreak and the WHO’s response to it. Situation reports were originally distributed as PDF files. More recently, they are published as both web pages and PDF files. Situation summaries, the latest communication device, first published on 14-Nov–14. They provide data tables with no analysis. Currently, the weekly data release is accompanied by a situation report and a situation summary. Interim or midweekly data releases are limited to a situation summaries.
The dates referenced in these tables are the cutoff dates associated with the data in a report, not the date the document was published. The cutoff dates for all countries in a report are not always consistent. Often data from Liberia lags that of other countries. Be that as it may, we use the primary date for each data snapshot as specified by the WHO.
