Scabies is a contagious skin infestation by the mite Sarcoptes scabiei. The most common symptoms are severe itchiness and a pimple-like rash. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline.
Scabies 是一种由微小螨虫引起的传染性皮肤病。这些螨虫会钻入皮肤,导致剧烈瘙痒,尤其在夜间更为明显。其主要传播途径是皮肤接触,因此家庭成员和密切接触者的风险最高。2009 年,世界卫生组织 (WHO) 将 scabies 列为被忽视的皮肤病,强调其作为公共健康问题的重要性,特别是在发展中国家。 Scabies is a contagious skin condition resulting from the infestation of a mite. The Sarcoptes scabiei mite burrows within the skin and causes severe itching. This itch is relentless, especially at night. Skin-to-skin contact transmits the infectious organism therefore, family members and skin contact relationships create the highest risk. Scabies was declared a neglected skin disease by the World Health Organization (WHO) in 2009 and is a significant health concern in many developing countries.
Permethrin 是一种用于治疗疥疮和虱子的药物,属于一类称为拟除虫菊酯的合成化学物质,可影响神经系统。Permethrin 的作用是扰乱虱子、螨虫等昆虫神经细胞中钠离子的流动,导致其瘫痪并最终停止呼吸。 Permethrin is a medication used in the management and treatment of scabies and pediculosis. It is in the synthetic neurotoxic pyrethroid class of medicine. It targets eggs, lice, and mites via working on sodium transport across neuronal membranes in arthropods, causing depolarization. This results in respiratory paralysis of the affected arthropod.
目前可使用多种药物治疗,包括 Permethrin(氯菊酯)、Crotamiton(克罗米通)、Lindane(林丹)乳膏和 Ivermectin(伊维菌素)。过去一个月内有性接触或同住一屋檐下的人员也应同步治疗。三天内使用过的床上用品和衣物应以热水清洗并用热烘干机烘干。治疗后症状可能持续两至四周,若仍未消失,需再次治疗。
疥 (Scabies) 是儿童三大常见皮肤病之一,另两种为癣和细菌性皮肤感染。截至 2015 年,全球约有 2.04 亿人受其影响(约占世界人口的 2.8%),男女发病率相近。年轻人和老年人更易受累,且在发展中国家和热带地区更为常见。
○ 治疗 - 非处方药
疥疮的一个显著特点是所有家庭成员往往同时出现瘙痒。部分药物(如 Permethrin(氯菊酯))可在非处方药 (OTC) 店铺直接购买。治疗应在全家范围内同步进行。
