Scabies is a contagious skin condition caused by tiny mites which burrow into the skin characterized by intense itching that is worse at night. It also causes a skin rash on areas where the mites have burrowed. Scabies produces a skin rash composed of small red bumps and blisters and affects specific areas of the body. Mites can live for about 2 to 3 days in clothing, bedding, or dust, making it possible to catch scabies from people who share the same infected bed, linens, or towels. It may take up to 4 to 6 weeks after infection for symptoms to appear in someone who's never had scabies before. In people who have had scabies previously, symptoms may appear in just a few days.
The areas of the body most commonly affected by scabies are the hands and feet (especially the webs of skin between the fingers and toes), the inner part of the wrists, and the folds under the arms. It may also affect other areas of the body, particularly the elbows and the areas around the breasts, genitals, navel, and buttocks. In infants and young children, the rash can be on the scalp.
Caused by a mite called Sarcoptes scabiei.
