Most human ectoparasites live on the surface of their host and depend on that host to complete their life cycle. The most common ectoparasitic infestations of medical importance in humans include pediculosis, scabies, myiasis, and tungiasis. Different host factors are related, with increased risk of acquiring ectoparasitic infestation occurring among the homeless. Although these ectoparasitic infections can be found worldwide, their prevalence is affected significantly by environmental conditions in different geographical areas. This review focuses on the epidemiology, clinical presentation, diagnosis, and treatment of common ectoparasitic infestations among homeless children and their families. The most frequent bacterial infections associated with these infestations also are discussed.
