In March 2014, after an increase of notifications of domestically acquired hepatitis A virus infections, an outbreak investigation was launched in Norway. Sequenced-based typing results showed that these cases were associated with a strain that was identical to one causing an ongoing multinational outbreak in Europe linked to frozen mixed berries. Thirty-three confirmed cases with the outbreak strain were notified in Norway from November 2013 to June 2014. Epidemiological evidence and trace-back investigations linked the outbreak to the consumption of a berry mix cake. Identification of the hepatitis A virus outbreak strain in berries from one of the implicated cakes confirmed the cake to be the source. Subsequently, a cluster in Germany linked to the cake was also identified.
2014年3月，在挪威国内获得性甲型肝炎病毒感染报告数量增加后，该国发起了一次疫情调查。基于测序的分型结果显示，这些病例与一种毒株有关，该毒株与在欧洲因冷冻什锦浆果引发的跨国疫情中发现的毒株相同。2013年11月至2014年6月期间，挪威共报告了33例确诊感染该疫情毒株的病例。流行病学证据和溯源调查将此次疫情与一款什锦浆果蛋糕的食用联系起来。在其中一款涉事蛋糕的浆果中检测出甲型肝炎病毒疫情毒株，证实该蛋糕为传染源。随后，在德国也发现了与该蛋糕有关的病例群。
