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 是一種由微小蟎蟲引起的傳染性皮膚病。這些蟎蟲會鑽入皮膚,導致劇烈搔癢,尤其在夜間更為明顯。主要的傳播方式是皮膚接觸,因此家庭成員和密切接觸者的風險最高。2009 年,世界衛生組織 (WHO) 將 scabies 列為被忽視的皮膚病,強調其作為公共健康問題的重要性,尤其在發展中國家。 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 是一種用於治療疥瘡和蝨子的藥物,屬於稱為擬除蟲菊酯的合成化學物質,會影響神經系統。Permethrin 的作用是擾亂蝨子和蟎蟲等昆蟲神經細胞中鈉離子的運動,導致癱瘓,最終使其停止呼吸。 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.
目前有多種藥物可用於治療,包括氯菊酯、克羅米通、林丹乳膏和伊維菌素。過去一個月內有性接觸或同住於同一屋簷下的人亦應同時接受治療。過去三天使用過的寢具和衣服應以熱水清洗,並以熱烘乾機烘乾。治療後症狀可能持續兩至四週;若此期間後仍有症狀,可能需要重新治療。
疥 (Scabies) 是兒童最常見的三種皮膚病之一,另外兩種是癬和細菌性皮膚感染。截至 2015 年,全球約有 2.04 億人受到感染(佔世界人口的 2.8%),男女發病率相近。年輕人與老年人較易受感染,且在發展中國家及熱帶氣候地區更為常見。
○ 治療 - 非處方藥
疥瘡的一個重要特徵是所有家庭成員同時出現搔癢。某些藥物(例如氯菊酯)可於非處方藥 (OTC) 購買,無需處方。治療應由全家人一起完成。
