Imported dengue into naive areas is a recognized but unquantified threat. Differentiating imported and autochthonous cases remains problematic. A threshold approach applied to Japan identified several aberrant incidences of dengue. Despite these alerts, no epidemics occurred other than 1 in Yoyogi Park in Tokyo, which was probably an unusual event.
输入的登革热对无免疫力地区是一个公认的、但尚未量化的威胁。输入病例和本地病例的区分仍然存在问题。日本采用的阈值方法确定了几例异常的登革热病例。尽管有这些警报,但除了东京代代木公园的 1 例(可能是一起不寻常的事件)外,没有发生其他疫情。
