Following outbreaks in other parts of the Netherlands, the Dutch border region of South Limburg experienced a large‐scale outbreak of human Q fever related to a single dairy goat farm in 2009, with surprisingly few cases reported from neighbouring German counties. Late chronic Q fever, with recent spikes of newly detected cases, is an ongoing public health concern in the Netherlands. We aimed to assess the scope and scale of any undetected cross‐border transmission to neighbouring German counties, where individuals unknowingly exposed may carry extra risk of overlooked diagnosis.

Q发烧：在荷兰-德国边境地区，大规模但尚未发现的跨界爆发证据，并有额外的死亡风险。

在荷兰其他地区暴发疫情之后，南林堡的荷兰边境地区在2009年大规模爆发了与单个乳山羊场有关的人类Q病暴发，德国邻县报告的病例极少。晚期慢性Q热以及最近新发现病例的激增，一直是荷兰持续关注的公共卫生问题。我们旨在评估任何未发现的跨境传播到邻近德国县的范围和规模，在不知情的情况下，个人可能会遭受额外的被忽视诊断的风险。
