Ebola virus disease outbreak, West Africa
An outbreak of Ebola Virus Disease (EVD) with onset in December 2013 is still evolving in Guinea, Liberia, Sierra Leone and Nigeria.
Gene sequencing of the virus causing the outbreak has demonstrated 98% homology with the Zaire Ebola virus last reported from an outbreak in 2009 in the Democratic Republic of Congo.
Case fatality ratios from previous outbreaks caused by this viral strain of the disease have been high.
Through both epidemiological updates and rapid risk assessments, ECDC provides updates on the impact of the disease and the risk to European public health.
