The importance of Japanese encephalitis (JE) in endemic populations and in travellers requires a balanced assessment. This disease represents an important public health problem in some endemic areas, which contrasts with the minimal risk for travellers to endemic areas. This is reflected by high numbers of infections mainly among children in endemic countries and by few case reports among tourists and even expatriates. The total number of case reports between 1978 and 2008 amounts to a risk of one to two cases per year. Nevertheless, some travelling groups may be at higher risk when visiting or working in high risk areas. A new vaccine against Japanese encephalitis will soon be registered in Switzerland. This paper contributes to the scarce data available for decision making whether or not to recommend the vaccination to tourists and expatriates.
日本脑炎（JE）在流行地区人群和旅行者中的重要性需要进行平衡评估。这种疾病在一些流行地区是一个重要的公共卫生问题，这与前往流行地区的旅行者面临的极低风险形成对比。这体现在流行国家主要是儿童中感染人数众多，而游客甚至外籍人士中的病例报告很少。1978年至2008年期间的病例报告总数相当于每年有1至2例的风险。然而，一些旅行群体在前往高风险地区访问或工作时可能面临更高的风险。一种新的日本脑炎疫苗很快将在瑞士注册。本文有助于为是否向游客和外籍人士推荐接种疫苗的决策提供稀缺数据。
