This is the fourth in a series of regular situation reports on the Ebola Response Roadmap1. The report contains a review of the epidemiological situation based on official information reported by ministries of health, and an assessment of the response measured against the core Roadmap indicators where available. Additional indicators will be reported as data are consolidated.
The data contained in this report are based on the best information available. Substantial efforts are ongoing to improve the availability and accuracy of information about both the epidemiological situation and the implementation of the response.
Following the roadmap structure, country reports fall into three categories: those with widespread and intense transmission (Guinea, Liberia, and Sierra Leone); those with an initial case or cases, or with localized transmission (Nigeria, Senegal); and those countries that neighbour areas of active transmission (Benin, Burkina Faso, Côte d’Ivoire, Guinea-Bissau, Mali, Senegal). An overview of the situation in the Democratic Republic of the Congo, where a separate, unrelated outbreak of Ebola virus disease is occurring, is also provided (see Annex 1).
OVERVIEW

Countries affected are Guinea, Liberia, Nigeria, Senegal and Sierra Leone. Figure 1 below shows the total number of cases by country that have been reported in each epidemiological week between the start of 30 December 2013 (start of epidemiological week 1) and end 14 September 2014 (epidemiological week 37: 8 to 14 September).
