Summary of influenza virus characterisation data reported by national influenza centres to The European Surveillance System for weeks 40/2017 to 20/2018.
Since the latest ECDC-EFSA rapid outbreak assessment published on 12 December 2017, 15 EU/EEA countries (Belgium, Czech Republic, Denmark, France, Hungary, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Poland, Slovenia, Sweden and United Kingdom) have reported 336 confirmed, 94 probable and 3 new historical-confirmed cases associated with this ongoing multi-country outbreak of Salmonella Enteritidis in the EU/EEA.
A multi-country outbreak of 12 listeriosis cases caused by Listeria monocytogenes sequence type (ST) 8 has been identified through whole genome sequencing (WGS) analysis in three EU/EEA countries: Denmark (6 cases), Germany (5) and France (1).
Ready-to-eat salmon products, such as cold-smoked and marinated salmon, are the likely source of an outbreak of listeriosis that has affected Denmark, Germany and France since 2015.
