Number of Ebola Cases and Deaths in Affected Countries

Data are based on official information reported by ministries of health. These numbers are subject to change due to ongoing reclassification, retrospective investigation and availability of laboratory results. The fewer cases reported this week compared with the Situation Report of 29 October is due to a change in the use of data sources. In this report, the cumulative total numbers of cases and deaths nationally and by district are identical to those presented in situation reports compiled by ministries of health and WHO country offices. Previously, these totals were derived from a combination of patient databases and country situation reports. The revised approach unifies the totals presented in this report with those given in national reports.

The WHO sitrep provide updated data for countries with an active Ebola outbreak. The WHO declared Senegal, Nigeria, Spain United States of America, Mali, the United Kingdom, Liberia, Sierra Leone and Guineato be Ebola free on 17 October, 20 October, 2 December, mid December 2014, 18 January 2015, 10 March 2015, 9 May 2015, 7 November 2015 and 29 December 2015 respectively. Although not reported in the sitrep, the cumulative figures from these countries are presented in the dataset for convenience. On 14 November 2014, Liberia has fewer deaths than the last update on 12 November due to reclassification. Data are based on official information reported by ministries of health, through WHO country offices. These numbers are subject to change due to ongoing reclassification, retrospective investigation and availability of laboratory results.
