Sarcoptes scabiei: a reemerging pathogen



Human scabies is an infestation of the skin by a mite called Sarcoptes scabiei var. hominis. Scabies is present all around the world and is prevalent in all age groups, mostly children and elderly people. This skin disease presents with severe itch and a papular rash, especially on the hands, feet and genitalia. Crusted scabies is a severe, highly contagious form of classic scabies. Delayed diagnosis and inadequate treatment can lead to worsening of the disease. The presumptive diagnosis is clinical and is confirmed by the visualization of the parasite, eggs or feces. Treatment includes topic therapy with permethrin or ivermectin, and systemic therapy with oral ivermectin. There are not many statistical reports about scabies. In Argentina, there are few case reports in the literature, but, nevertheless, scabies may be more common than reported. This article reports different aspects of the diagnosis, treatment and prophylaxis of the human itch mite.
