WHO response

WHO and partners are providing the necessary technical support to the Ministries of Health to stop community and health facility transmission of the virus. This includes a high-level advocacy meeting with the governments of the three affected countries to enhance coordination, information management, and communication, among others. The WHO Regional Director, in consultation with the Director General, has established a temporary function of WHO sub-regional EVD outbreak response Coordinator to directly support the affected countries. The Coordinator is based in Conakry, Guinea. In addition, WHO is organizing a high-level meeting for the Ministers of Health in the sub-region, technical experts and key stakeholders to be held from 2–3 July 2014 in Accra, Ghana. The objective is to ensure increased political commitment and enhanced cross-border collaboration for EVD response activities among the countries in the sub-region. WHO, GOARN, and other partners are also closely supporting the Ministries of Health in deploying additional experts in the various specialities (epidemiology, social mobilization, case management, data management, and logistics, among others) to support the EVD outbreak response efforts. The next cross-border technical meeting among the three countries is planned for 23 June 2014 in Kailahun, Sierra Leone.

WHO does not recommend any travel or trade restrictions be applied to Guinea, Liberia, or Sierra Leone based on the current information available for this event.


CORRIGENDUM

* In a Disease Outbreak News for Ebola virus disease (EVD) in West Africa, dated 22 June 2014 (http://who.int/csr/don/2014_06_22_ebola/en/), WHO reported 58 deaths from EVD based on best available information from Sierra Leone. The cumulative suspected, probable, and confirmed (including 3 new confirmed Ebola deaths) was 55 not 58. The new confirmed deaths were double counted. On 24 June 2014, WHO reported 34 deaths from EVD based on best available information from Sierra Leone. (http://who.int/csr/don/2014_06_24_ebola/en/) This discrepancy in numbers is a result of a change in the reporting methodology on the part of Sierra Leone. The new method did not include probable or suspect deaths and were only deaths of laboratory-confirmed cases. The reported cases in Kono and Western Area were suspect cases which have now proved negative. As of 24 June, there are no confirmed cases of Ebola in Kono and Western Area.

Going forward, in an effort to ensure clear information, a table will be presented in future Ebola reports in the Disease Outbreak News.
