This study aimed to describe the demographic and geographic patterns of campylobacteriosis in Denmark, Finland, Norway and Sweden during 2000-2015. All infections notified to national authorities in the four countries during the study period were included. Background data for each notification consisted of patient age, sex, geographical location, presumed origin of infection and date of sample taken or date of sample received in the laboratory. These data were analysed in order to investigate annual trends, age group and sex patterns, as well as variations in the geographical and seasonal distribution of infections. During the study period, a total of 164,001 infections, excluding travel-related cases, were registered, representing a mean annual incidence of 42.3 cases/100,000 population (ranging from 28.5 in Norway to 60.4 in Denmark). The incidence increased significantly from 2004 onwards in all countries, apart from Denmark. Males had higher infection rates in general. The highest incidences were observed in 0-4 year olds and those aged 20-29 years, apart from in Finland where there was no peak of infections in children aged 0-4 years. Seasonality of disease was distinct in all four countries, showing peaks of infection between July and August. In Sweden and Norway, incidences of campylobacteriosis were significantly higher in municipalities with high degrees of coastline or inland water.
本研究旨在描述 2000-2015 年期间丹麦、芬兰、挪威和瑞典的弯曲菌病的人口统计学和地理模式。所有在研究期间向四个国家的国家当局报告的感染均包括在内。每个通知的背景数据包括患者年龄、性别、地理位置、感染的推测来源以及样本采集或实验室收到样本的日期。对这些数据进行了分析，以调查年度趋势、年龄组和性别模式，以及感染的地理和季节分布的变化。在研究期间，共登记了 164,001 例非旅行相关病例，平均年发病率为 42.3 例/100,000 人口（范围从挪威的 28.5 例到丹麦的 60.4 例）。除丹麦外，所有国家的发病率从 2004 年开始显著上升。总体而言，男性的感染率较高。除芬兰外，发病率最高的是 0-4 岁和 20-29 岁的人群，在芬兰，0-4 岁儿童的感染高峰并不明显。所有四个国家的疾病季节性都很明显，感染高峰期在 7 月至 8 月之间。在瑞典和挪威，沿海地区或内陆水域比例高的城市中弯曲菌病的发病率明显更高。
