In May 2022, the Finnish Institute for Health and Welfare observed an increase in Mbandaka cases. Whole genome sequencing (WGS) linked the outbreak strain to a previously reported strain in the United Kingdom. From April 2022 to January 2023, 97 cases were reported across 18 of Finland's 21 hospital districts, with a median age of 27 years (range <1-74 years) and 61% female cases. Based on trawling interviews and national food consumption data, cases were more likely to have eaten at a restaurant or takeaway (odds ratio (OR) = 115; 95% confidence interval (CI): 52-256; p < 0.001) or consumed poultry products (OR = 28; 95% CI: 7-115; p < 0.001). A case-case study linked cases with consumption of ready-to-eat products containing chicken from a specific company (OR = 28; 95% CI: 1.9-1,361; p = 0.004). Traceback investigations identified a pre-cooked, frozen chicken meat product from a country outside the European Union as the likely source. Mbandaka was isolated from cases and linked by WGS to this chicken meat product. Our findings highlight the potential health risk of pre-cooked chicken meat containing and the value of case-case studies and product images to assist recall during food-borne outbreak investigations.
2022年5月，芬兰卫生和福利研究所发现班达卡病例有所增加。全基因组测序（WGS）将此次疫情毒株与英国先前报告的毒株联系起来。从2022年4月到2023年1月，芬兰21个医院区中的18个报告了97例病例，中位年龄为27岁（范围<1 - 74岁），女性病例占61%。根据深入访谈和全国食品消费数据，病例更有可能在餐馆或外卖就餐（优势比（OR）= 115；95%置信区间（CI）：52 - 256；p < 0.001）或食用禽肉产品（OR = 28；95% CI：7 - 115；p < 0.001）。一项病例对照研究将病例与食用来自特定公司的含鸡肉即食产品联系起来（OR = 28；95% CI：1.9 - 1361；p = 0.004）。追溯调查确定一种来自欧盟以外国家的预煮冷冻鸡肉产品可能是源头。从病例中分离出班达卡，并通过全基因组测序将其与该鸡肉产品联系起来。我们的研究结果凸显了含[此处原文缺失内容]的预煮鸡肉的潜在健康风险，以及病例对照研究和产品图片在食源性疾病暴发调查中协助召回方面的价值。
