Identification of essential outstanding questions for an adequate European laboratory response to Ebolavirus Zaire West Africa 2014.

On August 8 2014, the World Health Organization (WHO) declared the outbreak of Ebola Virus Disease (EVD) evolving in West Africa since December 2013, a Public Health Emergency of International Concern (PHEIC). It is expected that the outbreak of Ebolavirus Disease (EVD) in West Africa will lead to increased testing of individuals in Europe for EVD. The severity of the situation in West Africa warranted a critical appraisal of the laboratory preparedness and response for EVD, with a focus on information needs for laboratories involved in diagnostics of rare viral diseases associated with the European Network for the Diagnostics of "Imported" Viral Diseases", ENIVD. Essential knowledge and knowledge gaps for an adequate laboratory response focusing on virus properties, infection kinetics, tests specifics and field performances were identified. An inventory of the laboratory capacity for EVD diagnostics among ENIVD laboratories was made.
