1 July 2014-Ebola virus disease update, West Africa

Epidemiology and surveillance

Based on epidemiological analysis conducted by WHO, three major factors are contributing to patterns of transmission, which are currently responsible for the continuous propagation of Ebola virus disease (EVD) in the sub-region. These factors include transmission of EVD in rural communities, facilitated by strong cultural practices and traditional beliefs; transmission of EVD in densely populated peri-urban areas of Conakry in Guinea and Monrovia in Liberia; and cross-border transmission of EVD along the border areas of Guinea, Liberia, and Sierra Leone, where commercial and social activities continue among the border areas of these countries.

Health sector response

Containment of this outbreak requires a strong response in the countries and especially along their shared border areas. As one of the response elements, WHO is organizing a high-level meeting for the Ministers of Health in the sub-region scheduled for 2–3 July 2014 in Accra, Ghana. The meeting will bring together Ministers of Health and the Directors of disease prevention and control from 11 African countries (Côte d'Ivoire, the Democratic Republic of the Congo, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Senegal, Sierra Leone, and Uganda), as well as partners, Ebola survivors, representatives of airlines and mining companies, and the donor communities. The objective of the meeting is to analyse the situation, identify gaps, develop operational response plans, and to ensure increased political commitment and enhanced cross-border collaboration for EVD response activities among the countries in the sub-region.

WHO and technical partners in the Global Outbreak Alert and Response Network (GOARN), including the EU Mobile Laboratory consortium, the IFRC, and national societies, Institut Pasteur Dakar, Institut Pasteur Lyon, Institut Pasteur Paris, Bernard Nocht Institute in Hamburg, Médecins Sans Frontières/Doctors without Borders, Public Health Agency of Canada, Public Health England, and US CDC, together with UN agencies, DFID, EU, ECHO, and other partners are providing the necessary technical expertise and support to the Ministries of Health to stop community and health facility transmission of the virus. WHO is closely supporting the Ministries of Health through the deployment of additional experts in various specialties, providing field logistics support, and personal protective equipment and medical supplies.
