Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Human scabies, caused by the Sarcoptes scabiei mite, is one of the most common contagious dermatoses. In HIV patients, this organism can cause “crusted scabies,” also known as Norwegian scabies, which denotes an overwhelming scabies infestation. In typical scabies, the mites cause extremely pruritic burrows, vesicles, and papules in a characteristic distribution involving the finger webs, sides of the hands and feet, breasts, waist, and groin. Pruritus is most intense at night. In contrast, crusted scabies typically affects the hands and the feet with asymptomatic crusting and does not cause significant pruritus. Transmission through infected linens or clothing is common in cases of Norwegian scabies. Risk factors include poor hygiene, crowding, and exposure to pets.
