Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Human scabies is caused by Sarcoptes scabiei var. hominis, a mite within the epidermal layers. Transmission occurs after skin contact with an infected individual or possibly from infested clothing and bedding. The female mite burrows into the skin and deposits two to three eggs daily. Fecal pellets (scybala) are deposited in the burrow and may be responsible for localized pruritus, often nocturnal. The pink white, slightly elevated burrows are typically seen in the web spaces of the hands and feet, penis, buttocks, scrotum, or extensor surfaces of the elbows and knees. Crusted, or Norwegian, scabies seen in immunosuppressed or debilitated patients (see HIV chapter) usually present with asymptomatic acral crusting, but can occur anywhere.
