Pediculosis is an infestation of lice on the body, head, or pubic region that occurs worldwide. Lice are ectoparasites of the order Phthiraptera that feed on the blood of infested hosts. Their morphotype dictates their clinical features. Body lice may transmit bacterial pathogens that cause trench fever, relapsing fever, and epidemic typhus, which are potentially life-threatening diseases that remain relevant in contemporary times. Recent data from some settings suggest that head lice may harbor pathogens. The epidemiology, clinical manifestations, and management of body, head, and pubic louse infestation are reviewed. New therapies for head lice and screening considerations for pubic lice are discussed. Tungiasis is an ectoparasitic disease caused by skin penetration by the female Tunga penetrans or, less commonly, Tunga trimamillata flea. It is endemic in Latin America, the Caribbean and sub-Saharan Africa and seen in travelers returning from these regions. Risk factors for acquiring tungiasis, associated morbidity, and potential strategies for prevention and treatment are discussed.

外寄生虫：小儿dic虫病和真菌病。

虱病是在全世界范围内在身体，头部或耻骨区域上虱子的侵染。虱子是Phthiraptera阶的外寄生虫，以被感染宿主的血液为食。它们的形态决定了它们的临床特征。体虱可能传播引起trench热，复发性发热和流行性斑疹伤寒的细菌性病原体，这是可能威胁生命的疾病，在当代仍然很重要。来自某些环境的最新数据表明，头虱可能藏有病原体。本文对流行病学，临床表现以及对身体，头部和耻骨虱侵扰的处理进行了回顾。讨论了用于头虱的新疗法和对耻骨虱的筛查注意事项。gia虫病是由雌性Tunga penetrans或较少见的Tunga trimamillata跳蚤引起的皮肤渗透引起的外寄生虫病。它在拉丁美洲，加勒比海和撒哈拉以南非洲地区很流行，从这些地区返回的旅行者中也可以看到。讨论了获得眼病的危险因素，相关的发病率以及预防和治疗的潜在策略。
