Scabies

Scabies is an infectious disease caused by Sarcoptes scabiei var. hominis. The disease is mainly transmitted by close personal contact. The primary clinical picture is characterized by burrows at typical areas as well as severe pruritus, while secondarily a rather non-specific exanthema can be observed. The detection of mites or mite products (eggs, feces) confirms the diagnosis; dermatoscopy may facilitate the diagnosis. First choice therapy for most variants of scabies is topical permethrin. Oral administration of ivermectin is recommended for some special indications. In the following article, the current knowledge about epidemiology, biology, immunology, clinical appearance, diagnostic procedures and therapy of scabies is reviewed.
