Japan is currently experiencing many outbreaks of scabies, occurring mainly in long-term care facilities. Scabies burrows, the only pathognomonic lesion for scabies, often occur on the creases of the palms, and are followed by a pattern of scale reminiscent of the 'wake' left on the surface of water by a moving bird or a ship (wake sign).(1-4) The wake sign is useful because (i) it is specific for scabies, (ii) it is sufficiently large to be found by the naked eye and (iii) it points towards the location of the mite and its products. Examination of patients' palms to look for this sign is a simple and efficient way to make a diagnosis of scabies throughout the course of an infestation.
日本目前正经历许多疥疮的爆发，主要发生在长期护理机构中。疥疮的隧道，是疥疮的唯一特征性病变，常发生在手掌的褶皱处，随后出现鳞片样的模式，让人联想到移动的鸟或船在水面上留下的“尾迹”（1-4）。尾迹是有用的，因为（i）它是疥疮特有的，（ii）它足够大，可以用肉眼发现，（iii）它指向螨虫及其产物的位置。检查患者手掌寻找这个迹象是一种简单而有效的方法，可以在整个感染过程中诊断疥疮。
