定义
人疥螨对皮肤的高度传染性疾病。当被引入学校和疗养院等机构时，可能会导致流行病。螨虫钻入皮肤，喜欢四肢、生殖器和婴儿腋窝。丘疹性皮疹的特征是广泛而强烈的瘙痒，主要是由于宿主的反应，而不是直接由螨虫钻入造成的。免疫抑制或虚弱患者没有这样的反应，螨虫不加控制的增殖会导致结痂性疥疮。其他哺乳动物如狗的疥螨可能会引起短暂的瘙痒爆发。
A highly contagious infestation of the skin by the mite Sarcoptes scabiei var. hominis. It may result in epidemics when introduced into institutions such as schools and nursing homes. The mites burrow into the skin, favouring the extremities, genitalia and, in infants, the axillae. The characteristic widespread intensely pruritic papulovesicular rash results largely from the host response rather than directly to burrowing by mites. Where such a response is absent as in immunosuppressed or debilitated patients, unchecked proliferation of mites results in crusted scabies. Sarcoptic mites from other mammals such as dogs may cause a transient pruritic eruption.
人疥疮螨（人型疥螨）侵染皮肤，通过密切皮肤接触在人与人之间传播。螨虫钻入表皮，从而激发宿主的免疫反应，限制了侵染程度，导致剧烈瘙痒性丘疹的广泛炎症爆发。这些丘疹经常因表皮脱落而二次感染。在未能产生免疫反应的个体中，螨虫可肆意繁殖，形成含有大量螨虫的大面积结痂（结痂型疥疮）。
