我们分析了1995年至2004年期间向芬兰国家传染病登记处通报的肺囊虫病病例的监测数据，并描述了我们最近在调查肺囊虫病病例集群方面的经验。每年的病例数在18至53例之间，但没有发现发病率的趋势（平均年发病率为每百万居民7例）。只有少数病例影响孕妇或新生儿。大多数患者是患有非恶性基础疾病的老年人;其中25%死于感染。通过常规的血清和基因分型，我们发现了几个集群，感染的车辆只确定了两次爆发。至少有四分之一的鱼病病例（78/315）是由某种血清基因型或密切相关的基因型引起的，这些基因型也在真空包装的冷熏鱼或冷腌鱼产品中发现。在2000-2003年期间，芬兰消费者多次被告知对危险群体的食品预防措施。这些信息也被提供给主治医生和产前clinics.We的监测数据进行了分析，从1995年至2004年之间通知芬兰国家传染病登记册，并描述了我们最近的经验，在调查集群的猪囊虫病病例。每年的病例数在18至53例之间，但没有发现发病率的趋势（平均年发病率为每百万居民7例）。
We analysed the surveillance data from listeriosis cases notified to the Finnish National Infectious Diseases Register between 1995 and 2004 and describe our recent experience in investigating clusters of listeriosis cases. The number of annual cases varied between 18 and 53 but no trends in incidence were identified (average annual incidence was 7 cases per million inhabitants). Only a few cases affected pregnant women or newborns. Most of the patients were elderly people with non-malignant underlying illnesses; 25% of them died from their infections. By routine sero- and genotyping of the listeria isolates, we detected several clusters; the vehicle for infection was only identified for two outbreaks. At least one quarter of listeriosis cases (78/315) was caused by a certain sero-genotype or closely related genotypes, which have also been found from vacuum-packed cold-smoked or cold-salted fish products. During 2000-2003, Finnish consumers were repeatedly informed about food precautions for risk groups. The information was also given to attending physicians and prenatal clinics.We analysed the surveillance data from listeriosis cases notified to the Finnish National Infectious Diseases Register between 1995 and 2004 and describe our recent experience in investigating clusters of listeriosis cases.
