Increased migration volume and different Hepatitis B prevalence between immigration and emigration countries have changed the Hepatitis B virus (HBV) epidemiology considerably in Northern and North-Western European migrants-receiving countries. Due to the difference in migration status monitoring, the HBV infection data on migrants are not easily comparable among those countries. The study aims were: to compare the migration status indicators used by the national surveillance system in six Northern and North-Western European countries (the Netherlands, Germany, Finland, Denmark, Sweden and the UK); to determine the impact of the migration status on HBV infection by comparing the available data on prevalence and transmission routes of Hepatitis B in the migration and the general population in the six countries; to recommend sensible indicators and pertinent measures for HBV infection surveillance and control in the region.
Literature review, statistical data analysis on migration and HBV infection in the six countries; expert interviews to identify migration status indicators used in national surveillance systems.
Evident differences were found between the migration and the general population in Hepatitis B prevalence and transmission routes in the six countries. Migration status is monitored differently in six surveillance systems; immigrants from high/intermediate Hepatitis B endemic countries constitute a substantial proportion of HBsAg(+) and chronic cases in all six countries.
International migration has an obvious impact on Hepatitis B prevalence in the six countries. It is important to include common migration status indicators and to collect comparable data for HBV infection surveillance in different notification systems.
移民数量的增加以及移民和原籍国之间乙型肝炎（HBV）流行率的不同，使得北欧和西北欧移民接收国的 HBV 流行病学发生了重大变化。由于移民状况监测的差异，这些国家之间的移民 HBV 感染数据不易比较。本研究旨在：比较六个北欧和西北欧国家（荷兰、德国、芬兰、丹麦、瑞典和英国）国家监测系统使用的移民状况指标；通过比较六个国家移民和一般人群中乙型肝炎流行率和传播途径的现有数据，确定移民状况对 HBV 感染的影响；为该地区 HBV 感染监测和控制推荐合理的指标和相关措施。
文献回顾，对六个国家的移民和 HBV 感染的统计数据分析；专家访谈，以确定国家监测系统中使用的移民状况指标。
六个国家的移民和一般人群中乙型肝炎流行率和传播途径存在明显差异。六个监测系统对移民状况的监测方式不同；来自高/中乙肝流行国家的移民构成了所有六个国家 HBsAg(+)和慢性病例的主要部分。
国际移民对六个国家的乙型肝炎流行率有明显影响。为了进行不同通报系统的 HBV 感染监测，纳入共同的移民状况指标并收集可比数据非常重要。
