Importation and transmission of measles via air travel is a public health concern to countries, which are close to or have achieved elimination, i.e., to the majority of countries in Europe. In 2018, two measles cases occurred in Berlin residents, who flew within Europe while being infectious. In addition to contact tracing through passenger manifests, we contacted national authorities in flight destination countries or embarking countries and inquired about epidemiologically linked measles cases to the two Berlin index cases. We identified eight epidemiologically linked cases (six males, median age: 32 years) from three countries associated with three air-travels. Consequently measles was imported to Germany (Bavaria), Denmark and possibly Sweden. Our investigations revealed impediments to an effective public health response indicating the need to revisit current guidelines and methods to better control transmission of measles related to air travel.

通过航空旅行进口和传播麻疹是对那些已经接近或已实现根除的国家（即欧洲大多数国家）的公共卫生关注。2018年，在柏林居民中发生了两例麻疹病例，他们在欧洲传播而受到传染。除了通过旅客舱单进行联系追踪外，我们还与飞行目的地国家或登船国的国家当局进行了联系，并询问了与两个柏林索引病例在流行病学上相关的麻疹病例。我们确定了来自三个国家的三个与航空旅行有关的流行病学相关病例（六名男性，中位年龄：32岁）。因此，麻疹被进口到德国（巴伐利亚），丹麦和瑞典。
