Food-borne hepatitis A outbreak
An outbreak of hepatitis A infection has been reported in Denmark, Finland, Norway and Sweden over the last six months with 68 cases reported as of 17 April 2013, an additional two being reported this week. The source of the outbreak has not been identified but epidemiological investigations in the affected countries point towards frozen berries as vehicle of infection. ECDC’s assessment is that this is this is a multinational food-borne outbreak with a persistent common source. ECDC and the European Food Safety Agency published a joint rapid outbreak assessment on 16 April.

Influenza virus characterisation, December 2020

As of week 53/2020, only 415 influenza detections across the WHO European Region had been reported; 50% type A viruses, with A(H3N2) prevailing over A(H1N1)pdm09, and 50% type B viruses with only four having been ascribed to a lineage, three B/Victoria and one B/Yamagata.
